Cons: "No USB charging point working and I had purchased on board wifi"

Cons: "No USB charging point working and I had purchased on board wifi"
Pros: "The selection of movies was great. Boarding happened super fast and plane departed early."
Cons: "Plane was incredibly cold! Touch screen didn’t work well. Breakfast was lame. Flight attendants were super loud during breakfast service even though the lights were still dimmed."
Pros: "The price point."
Cons: "Service was terrible, staff was rude. For an international flight they provide you next to nothing. Only 1 meal and soda or water. They didn’t even have coffee or give napkins with the meal. The seats were smaller than usual and uncomfortable. In addition they lost our luggage."
Cons: "Poor customer service"
Cons: "Customer interaction is a joke"
Cons: "It would have been nice to have a free drink and snack on the short flight. We would have taken some with us on the plane if we would have known that we had to pay for everything. Just something we have never experienced on any international trip before"
Pros: "Not much"
Cons: "Our bags were lost, no apologies (in fact, the phone was put down on me twice), when the bags were returned after 24 hours, one was damaged and had to be replaced at my expense....no chance of a refund. My family and I will NEVER TRAVEL WITH AER LINGUS AGAIN....the worst airline in the world"
Pros: "On a 7 hour flight you want comfort. It was so smooth and easy. Watched movies, read, just relaxed. I've flown with Aer lingus before and it was just as amazing. I will ALWAYS use Are Lingus when I fly to the UK or Ireland and Shannon is a Gem of an airport. Most amazing airport I have ever been to!"
Pros: "Food was excellent and the movies were free."
Cons: "Our seats wouldn’t lean back. Other people’s did however."
Cons: "Aer lingus uses double prong headphones which dates the whole experience earphones are uncomfortable and volume is bad. You have to pay for booze in economy for international flight, seats aren’t that comfortable but the selection of movies and tv is good. I will probably look elsewhere next time"
Pros: "Crew helpful and friendly."
Cons: "Announcement could be clearer. Sometimes gabled and indistinct."
Pros: "Great equipment. Decent entertainment, sparsely filled cabin. Seat change to isle request before boarding readily made with no fuss. I noticed that passengers could actually make out pa announcements both at PDX and in flight. Doesn’t bother me anymore when I can’t but can be very concerning to anyone who rarely flies. Never understood going to the trouble of making announcements both pre-boarding & on-board pre-flight, that no one can even make out. That was not an issue here."
Cons: "Better lumbar support is always appreciated, adjustable lumbar would be very nice and could make or break an entire flight. No seat on any flight should ever be even the slightest ill repaired. Again, this equipmemt all seemed great. Lastly, since I prefer to always have a water, coke or coffe and or snack in front of me during entire flight, a bit of self serve (grab a water, coffee or snack yourself without having to make staff work a simple task would be nice on every flight. The flight from SEA-DUB was basically great and equipment is always of the utmost importantance."
Cons: "Flight was about an hour late taking off"
Pros: "Not a lot"
Cons: "The flight was delayed for 6 hours due to a mechanical problem. For 6 hours the passengers were told little or nothing & were eventually given a voucher for $10 to redeem on plane. Mechanical problems can of course occur,but how the airline,Aer Lingus,dealt with this was appalling."
Pros: "N/a"
Cons: "my seat wouldn't stay up, kept sliding back seat27a."
Pros: "Lots of entertainment. Spacey seats and plenty of bathrooms."
Cons: "The food wasn't great and I wish they would have picked up the dinner trays way sooner"
Pros: "I loved that they had blankets and pillows available, and the seats overall were comfortable. I also loved the in seat screens so we could watch movies. The select was a little limited compared to other airlines, but they still had some brand new releases. They also fed us two meals and a snack, and the crew was super nice."
Cons: "The boarding process was a little confusing. It was done by row numbers but not very well announced, so I wasn’t actually sure when my row was supposed to board."
Pros: "Flight was excellent as well as the,crew."
Cons: "Plenty of food snack etc. Entree taste mediocre at best"
Pros: "Plane was half full."
Cons: "Food was terrible, and if you’re white and your significant other is black you may have to request things for her because she won’t get them even when she asks"
Cons: "The flight was nearly an hour late taking off."
Pros: "Quick organized boarding, friendly staff, much better flight than I expected. Food was even pretty good...Customs in Shannon was MUCH easier than Heathrow would have been, so thankfully, I went through customs in Shannon."
Pros: "Crew remained civil under duress"
Cons: "Flight delays going over and coming back"
Pros: "The leg room was smaller some of the other airlines. The seat was so uncomfortable to sit on for the flight."
Cons: "Seat"
Pros: "On time flight"
Cons: "Made me check my carryon bag then it was opened - why - don’t know - and items missing along with my luggage strap. Will NEVER use Aer Lingus again"
Pros: "You lost myluhgage. I have no clean clothes to ware"
Pros: "Fast efficient boarding. Short flight so no issues."
Pros: "We got to Berlin quickly..."
Cons: "Could not choose seats Could not check in online Was not informed of the correct departure terminal Had to pay for drinks onboard Long distances between gate and terminals, seemed like the flight was 2nd class in terms of airport gate locations...."
Pros: "Tail winds shortened the flying time by 45 minutes"
Cons: "seats... no space menu.... skip it movie choice ... fair at best"
Pros: "I like the comfort and reliability of this airline in my experience."
Pros: "Easy check in, one free bag, and helpful flight staff"
Cons: "Absolutely no complaints. Great and easy flight."
Pros: "Nothing."
Cons: "First time I flew with Aer Lingus and can't say I will do it again. Didn't realize I was flying across continents in such a small plane. The flight attendants were barely civil; the bin above me housed supplies and on more than one occasion an attendant with visibly wet armpits leaned over me without nary an excuse me."
Cons: "Early boarding.. wondering could this catch me out on another occasion?"
Pros: "We had an excellent experience flying with Aer Lingus! We had a little trouble in the beginning due to my husbands CPAP machine. We did not realize you need a doctor’s note in order to fly! The first girl, Ajla, was sweet and just doing her job as she explained to us that we needed the note. My husband and I were upset, but she remained calm and kept a smile on her face. She got her supervisor, Ismail, to help us with our situation. We were able to resolve our problem with his help and check into our flight. Sean P helped us check into our flight and got us all situated. Ismail was amazing and upgraded our seats AND escorted us through security to make sure we would get to our flight with extra time to relax before we boarded! After our rocky start at check in Ismail made everything all better!! I highly recommend this Aer Lingus team at Logan International Airport!"
Pros: "On time. Reached early"
Cons: "No compliments of drinks"
Cons: "My issue has more to do with after the flight, than the actual flight. My luggage was lost somehow between Heathrow and Shannon. The lack of communication I received from Aer Lingus, and the length of time it took for me to get the luggage was a bit ridiculous. I was never told what happened to the luggage and I was given the timeline to receive my luggage within 24 hours. Well it took over 48 hours to get the luggage. I was given specific timeframes to call the Shannon Airport Aer Lingus luggage desk, which I followed. Had to leave a message every time, and not once was it returned. The only communication I did get was calling the Shannon Airport directly and working with their employees. I could tell they were frustrated with me, which is completely understandable, because they weren't the appropriate people to communicate with. I was just very disappointed in the customer service."
Pros: "I missed the flight, and was put on a scheduled one for the next day. Also, I love the fact that I can do customs before arriving stateside."
Cons: "The air conditioning on board was FREEZING. It took three tries to get a blanket."
Pros: "The effort made by the flight crew to find someone who was willing to switch their emergency exit seat with my cramped seat."
Cons: "Seating was really a disgrace. Being 6'3" made it unbearable. Seats are way too narrow and leg room non existent. Especially if the person in front of you reclined their seat."
Cons: "A/c was not working and is not the first time that happened on aerlingus....my question is do you do maintenance on aircraft??????"
Pros: "Flight attendant was delightful."
Cons: "See above"
Cons: "No TSA precheck Confusing check-in based on counter location and inexperienced agents."
Cons: "We froze the entire trip each way as we had the exit seats"
Pros: "The in-flight staff were also very helpful."
Pros: "Caring staff"
Cons: "Plane was so cold I kept loosing the feeling in my fingertips!"
Cons: "The food was not tasty. Poor flavor. I had the Shepherds pie. And although I was grateful to have a meal offered, this one was a little off in flavor."
Pros: "Everyone is so nice!"
Cons: "My food request was ignored. I requested vegan meals and the crew told me they were not notified of this and it was not available"
Pros: "The crew was incredible!"
Pros: "Service"
Cons: "Not enough leg room.."
Pros: "The food and the crew totally good"
Cons: "Maybe the toilets, need to be clean at least once in a flight"
Pros: "The leg room was really great!"
Cons: "Difficult finding room in over head bin for carry on bags."
Pros: "Crew was super nice"
Cons: "Airline to be more user friendly with connecting to free entertainment"
Pros: "Crew was efficient and pleasant making for a good experience."
Cons: "Nothing"
Cons: "Flight attendant seemed tired."
Pros: "Smooth operation"
Cons: "WiFi is horrible"
Cons: "The staff at the Seattle airport were very rude. The AAInflight wifi doesn't work at all. The Starbucks at Seattle had horrible service. I ordered a grande frappuchino and the cashier said it was a grande. When I got it it was a venti and I got charged extra and the woman who gave it to me was very very rude and sounded bored. She had blue hair. There was a woman who worked there who should be fired you couldn't understand a word she said and got the orders wrong."
Pros: "The amount of people on the flight was nice,for everyone was able to spread out on the entire plane."
Cons: "The turbulence during the whole flight was terrible."
Pros: "entertainment (movie) selection was good. would nice to have subtitles available"
Cons: "one flight attendant didn't seem very happy, not very nice serving drinks"
Cons: "Our original flight was delayed then cancelled. After assigning to another flight, it was delayed and gate changed about 10 times and was finally cancelled after it was boarded and left gate after 2am due to engine problem. We had to cancel our trip since it was a short trip for a funeral and we had missed it. AA offered no compensation and no apology (not during the whole night of delays and cancels)."
Pros: "They were rude and disrespectful."
Cons: "They were rude and disrespectful."
Pros: "The flight got me there"
Cons: "WiFi was too slow to be able to watch anything. Seat small and uncomfortable. Flight attendants not friendly."
Cons: "Boarding could be improved if they would start boarding from the back of the plane to the front after boarding 1st class and Priority this way people would not block the passage when putting their luggage in the top compartments. The crew was not very helpful because I almost went into a hypothermia condition because the air in the cabin was extremely cold. When I ask for a blanket one of the stewardesses said that AA would no longer have blankets in flight which I prove it wrong when I saw in the flight Mai-SDQ blanquets all over the cabin. The soliton they gave me was that they would ask the crew to raise the temp in the cabin, I had to make the request three times and I had to tell the stewardess that if not raising the temperature in the cabin I could have gone into an emergency hypothermia crisis. I had to take another shirt from my carry-on to put it over my shirt to warm me up."
Pros: "On time and the staff was great"
Cons: "Nothing"
Cons: "Boarding was delayed due to maintenance on top of arriving late. No entertainment on board. Only option for snack was salted pretzel???"
Cons: "Flight was delayed for whatever reason. Did not give us a reason why. Also boarding was very haphazard. They just boarded all groups at once to try to make up some time. Almost did not make it to our connecting flight in time"
Cons: "The Crew Tried to take us from our seats so they could sleep in our seats. They tried to relocate us to the last row where the seats don't recline.they were very abusive and rude, we have it all on a body Cam and we'll lodge formal charges against American Airlines once we return to the States. Worse Trip EVER."
Cons: "Not enough time in London to change planes. We missed the flight"
Pros: "For this flight I was seated in first class (I scheduled it this way; it wasn't due to a last minute upgrade) and the flight attendant was very personable and attentive :-) Service was wonderful and the meal was great! Of course, the flight attendant made sure to keep our beverages topped off as needed. It was a wonderful experience"
Cons: "The boarding process for just about any airline is nearly identical. It always seems like it takes longer to board than expected even if, in reality, it's not an unreasonable amount of time. The only think I didn't care for was that overhead storage in the area I was sitting was just about full by the time I was seated which meant that I had to store my carry on a few rows behind where I sat. This meant that during off-boarding I needed to go against the flow of people to get back to my carry on. All in all, it was a minor inconvenience."
Pros: "Our pilot was great. Kept us informed, was pleasant and got us in early. I appreciated the extra information he provided regarding expected turbulance and arrival updates."
Cons: "There wasn't individual entertainment unless i used my own device."
Pros: "Nice entertainment options."
Cons: "No free WiFi for message."
Pros: "seats comfy, seemed like a newer plane, crew was lovely."
Cons: "usual complaints about domestic flights - not having free headphones and not having free snacks."
Cons: "We are letting too many people with the flu, travel. This in turn is spreading it to other places and getting too many people sick. We need to control this more. I don’t have an option after spending all this money on if I can stay healthy or not, and that is not ok."
Pros: "Great service!"
Pros: "I would like if for my return from Paris to Chicago, Chicago Seattle I would be greeted by the personal and offered to flight first class without extra charge to compensate for the bad experience on my way going in. Thank you"
Cons: "I was told I would be able to choose the seats only 24 hours before the flight by going online. I tried to choose the seats online but could not have access to the site. I then called the number provided to ask for more help, and was told that I could then only choose the seats at the check in time. I was at the airport 2 hours before the flight schedule to book my seat and was told them that I could only choose the seats at the gate. Once I got at the gate I asked the person to please give me a seat at the aisle for medical reasons but after waiting until the boarding process had started I was giving a middle seat. Not only I was treated as a stand by passenger that had not purchased the tickets I was put nt on group 8 and at the moment of boarding the gate personal aggressively grabbed my carry-on bag because they insisted there was no more spaces in the compartment above heads. Once I got inside of airplane I saw many empty compartments available for carry-on luggage. I wish I had not purchased my ticket with Iberia Airlines operated by American Airlines. It was not a good, pleasant experience and do not recommend. I wil certainly avoid in the future and not travel this way another time. Thanks"
Pros: "Like the clean, comfortable seating. Great crew service and in time!"
Cons: "n/a"
Pros: "loved having a movie to pass the time. Super friendly attendants."
Pros: "love it!"
Cons: "b/a"
Cons: "Flight was delayed because of weather. No fault of carrier."
Pros: "Flight was ok, staff was professional and friendly. A good cleaning would be great. I'm average height and light build for a woman but I find the seats really are snugger than ever."
Cons: "AA didn't notify me of their change to my itinerary so I missed my flight, they cancelled my return flight from Europe, and only offered to refund my ticket when I spoke to a supervisor. I drove 5.5 hours to another city to catch a flight to Europe, believing my return ticket was valid as AA first told me, only later to learn they cancelled it. Thanks to AA, I currently I have no return ticket. Others on this flight and on my later Iberia flight were cursing AA loudly so I don't think my issue is an anomaly, but is more likely AA's new standard of conduct."
Pros: "On time for both flights"
Cons: "N/a"
Cons: "We haven't left yet"
Pros: "Got me to Dallas"
Cons: "Delays, felt like a hurded cow"
Pros: "The flight was on"
Pros: "On time"
Pros: "Kind and attentive crew"
Cons: "Was a bit delayed"
Cons: "The flight being delayed & then cancelled at the last second"
Pros: "Entertainment"
Cons: "Too many levels of passengers"
Pros: "Very efficient boarding, comfortable coach seats, good crew"
Cons: "No food! except pretzels and sandwiches for purchase. I didn't purchase a sandwich but the two guys next to me did and were both vocal about their disappointment with what they received for $9. And they were strangers who didn't talk to each other the rest of the time, so I think they meant it. Also, entertainment: they had a movie on the pop-down screens, and 4 free movies to stream to your device using onboard wifi, as well as 2 tv shows. So maybe I'm being harsh. But it was a transcontinental flight and they didn't have headrest screens loaded with movies. Is this only for international flights? The movies were bad, or at least not appealing to me ('Keanu' and 'Zoolander 2'). It was possible to pay for additional movies, but who wants to do that? It was sort of the EasyJet model, where you get good basic service but pay for everything additional that one gets for free on Delta. Maybe that was reflected in the price I paid for the ticket, but I was expecting that AA would be in the same league as United and Delta. One nice perk: free wifi for T-Mobile customers, including me."
Pros: "On time. No issues. The last two times I have flown Delta I've had issues. Smooth sailing"
Pros: "On time. Friendly crew. Good price."
Pros: "They switched my flight promptly when I missed my connection."
Cons: "I missed my connection for no apparent reasons. When asked for compensation they said there was nothing they could do and cited reasons Regarding the boarding and deboarding of a special needs passenger."
Pros: "It was great!"
Pros: "Seats were fairly comfortable"
Cons: "No in flight movie"
Cons: "My flight was delayed 2+ hours which made me miss my connecting flight & not make it to my destination until the next day ."
Pros: "I know AA and Alask are same company but I bought Alaska ariline ticket and everything I need to deal with is AA. It's too confusing."
Cons: "Too confused!"
Cons: "Fat constantly moving man next to me"
Pros: "free entertainment"
Pros: "Help that I received from check in through security to the gate was awesome. The person who checked me in offered me a wheelchair as it was a pretty long distance to the gate. I don't think that I would have made it all the way without her for thought and help! Same goes after the flight when we landed in Philadelphia. From the plane to gather my luggage and then to the place where my ride could pick me up. Awesome service. The stewards were also very helpful to keep me supplied with ice for my dogs. They get very stressed and tend to overheat. Thanks to a couple of the staff, especially, my dogs stayed very comfortable as well. Other then the fact that they got too warm a couple of times. Will definitely keep American in mind for another flight."
Cons: "I have not got a background in flying. I read the literature in the seat in front of me but I would like to have known sooner that I could turn a knob to help get cool air on my dogs. They were getting very warm and I spent a great deal of time fanning them when I could have just let the air do it's job."
Cons: "They boarded group 1 all at once. I was group 2. They boarded all of us all at once. It was a cluster!. I haven't flew in 6 years. But when I did they boarded by so many rows. Not all at once . Boarding was horrible. It was like a cattle drive."

Departed 3 hours late. Missed connection and they rebooked the convention but didn’t announce that in the cabin. Crew seemed stressed. Polite but not friendly. Cabin service in economy didn’t offer the usual water, soft drinks, coffee or tea, only offered things for sale. Had a roasted veggie sandwich that sounded so good but it was shrink wrapped, with cold, soggy bread, and a minuscule amount of vegetables. It was awful.

Flight on an 80 passenger plane was overbooked by 10 people. Next and last flight also overbooked, so that I had to overnight in Seattle and catch a flight the following day. Although my ticket had been purchased from Air Canada, it had been purchased by a third party, so the airline refused to pay for my overnight hotel. The gate agent was polite and did her best to get me on, but she could not do the impossible.

Cons: "The flight was delayed by 3 hours making me late for the next two flights and ultimately costing me an entire day longer in transit. While I understand these things happen, Air Canada's response to me asking for help was abysmal. Ultimately, they didn't care and told me it was my problem. Sadly, one of the first people I talked to really did want to help and arranged flights that would have gotten me back on track but he was prevented from confirming the changes due to management. I will never fly with Air Canada ever again."
Pros: "Cancelled 30 minute flight up to Vancouver which reaulted in missed flight to Australia. Air Canada the refused to put us on another flight. Went round and round for 5 hours with Air Canada until they finally put us on 3 separate flights getting to our deatination almost 48 hours late.Horrible"
Cons: "Notify passengers if short flight has more than 20% chance of being cancelled. We could have easily driven to Vancouver. If flight is cancelled, then own up to it and put people on next flight."
Pros: "N/A"
Cons: "Boarding in the rain is definitely not a good experience! The flight delayed so long that some of us who had connecting flights had to run from gate to gate (including clearing Canada customs) within 20 mins. Last but not least, Taipei Taiwan should NOT be listed as China."
Pros: "Boarding was easy and efficient"
Cons: "We paid an extra $100 for each ticket for premium seating, supposed to be a step above the basic coach ticket with more leg room (my partner and I are 6'+), but our seats were no different than anyone else's. In fact, the seating chart the agent provided for selection when on the call to add this was not for this plane, as it turned out. We will be requesting a refund!"
Cons: "Unreliable flight, always late, not staff at the check in terminal"
Cons: "Food was mediocre, I’d expect a bit more for the price paid."
Pros: "Nothing"
Pros: "Nothing"
Cons: "Took 3 hours to get our drinks. Completely out of inventory with food and snacks. Very hot on the plane . WiFi didn’t work/ they charged for headphones which i haven’t even heard of. My tray table was completely crooked , i had to place my drinks on my husbands table. Overall, just terrible."
Pros: "Nothing"
Cons: "I was unable to board because I didn't have an ETA - I was unaware of this requirement until check in. I was only transiting thru Canada - the ground staff were horrible."
Cons: "2 hour delay. Missed the connection in Vancouver in which crew could not be found and were not helpful. Ended up using another airline's counter for help to catch another flight out. Luggage was left in Vancouver. Eva Airline helped with luggage location and shipping to final destination."
Pros: "Wifi was great with very little disruptions. Service on the flight was expedient and frequent. In seat entertainment was excellent"
Cons: "I had the only seat on the row with no power for devices. All seats have USB power, but I was working on a laptop and had no AC power. The other seats did. This seems to be the case for the window seats on the right side of the plane and the aisle seats on the left side of the plane."
Pros: "Air Canada's airplane cleanliness is second to none in my book. That's why I always fly with them... Or rather flew..."
Cons: "The unending stream of excuses and explanations failed to convince me that this was anything but mismanagement that caused a delay of 5 hours. We'd be told something, and told the exact opposite, or a contradicting statement 15 minutes later. You botched this one bad Air Canada."
Pros: "the crew was very kind with getting those with close connecting flights off first."
Cons: "it was an hour late."
Pros: "None"
Cons: "Better luggage Service"
Pros: "movie selection on international flight was great."
Cons: "Had a serious delay, which was not acknowledged in anyway. We just waited near the gate for a long, long time. Also, for one of my flights, my group number was never called. I asked the flight attendant about it (when I passed through the gate after most other customers had boarded) and she flippantly responded with something like, "Yeah, maybe I didn't call your boarding zone. I don't know. Whatever." This left a terrible first impression on me."
Pros: "Nice plane."
Cons: "WAY too hot."
Pros: "Nothing. NOTHING."
Cons: "It took two hours to check my bag at the airport. The plane engine needed to be jump started, and I missed my connection flight to Paris. I had to spend an entire day stuck in Toronto, sick from terrible Hotel and airport food, cheap vouchers for terrible food, I missed my traveling companion who made the flight to Paris. I left my hat on the plane after the terrible flight in which they refused us any basic courtesies for the numerous passengers who were about to be stranded, and then the grooming crew kept my hat instead of turning it in to lost and found. Best part? Customer service told me that since I booked via Kayak, that I was not a valued customer and that they would not extend any courtesies to me for destroying my work trip itinerary."
Cons: "Took forever to board"
Pros: "Friendly service is so important to me - and the staff and flight crew at Air Canada met all my expectations. I had the displeasure of flying United on the way to Seattle and I must say the service at Air Canada is far above!"
Pros: "Short, comfortable seats"
Pros: "The seats were fairly comfortable for such a small plane."
Cons: "There was no meal on an international flight of more than four hours."
Cons: "Flight delayed again and again. Waited for hours at the airport until they cancelled the flight."
Pros: "Movies"
Cons: "Food was terrible especially for Prem economy. Chicken dish very bad. Difficult to get a second glass of wine with main meal."
Cons: "Numerous people had oversize carry on luggage that should have been checked. The passengers like me had smaller than regulation carry on but there did not seem to be room in the overhead compartments."
Pros: "Not much"
Cons: "I was too tall for the seats and the person in front of me was unable to put there seat back, they wanted me to trade with someone else but the. I just would have been a problem for someone else. The steward made me feel as though I was at fault because I should have payed the extra 100 to have emergency exit seating, they tried to get me to sit in the very back row of the plain and sit sideways across the two seats which means I would not be able to sit next to my fiancé. The whole thing was embarrassing and very rude, maybe people of 6'6" should be charged for emergency exit!!"
Pros: "I was not charged overweight for going over by 2 pounds since I had a Business Class ticket connection to my final destination."
Cons: "For an almost 4 hours, 400 USD international flight I would have expected to have at least a snack to eat a one luggage to check in on the price. I am an international traveler which doesn't have a choice but to carry a suitcase. Not to say that once on board I was requested to check in my carry on because there was no room on the plane and that I had to travel with my personal item on my feets since there was no available room at the over the head compartiment since I was identified with Zone 5 boarding."
Pros: "Service in the cabin was great."
Cons: "Can't think of anything"
Cons: "Flight was delayed 3 hours"
Pros: "Comfort. Individual screens"
Pros: "Superb experience all around....comfortable, clean, good entertainment, on-time, good food curteous crew!"
Cons: "Nothing- we will definitely travel with you again!"
Pros: "The flight was on time"
Cons: "This was an overnight flight and we had our seats changed to the back row without being told. The seats would not recline and when the seats in front of us reclined for the entire flight, the screen and chair were about a foot from our faces. This was hands down the worst flight I have ever had. The flight crew Wulf not move us as the flight was full, and despite there being more than half of the first class seats available, they would not let us sit there. I will likely not fly air canada again given this experience."
Pros: "Food was good, service good in business cabin"
Cons: "We left late, and despite it being obvious we were going to leave late, all the information posted at the gate and on the web said on time. Why is it that airlines don't tell the truth about departures and arrivals times?"
Pros: "Didn't have much good with air canada. Some of the worst customer service I've experienced. Flight was fine."
Cons: "Boarded an hour late, made us miss our layover even though they said they were holding our following flight to Tokyo. The both of us along with 10 others on our flight got to the gate 10 minutes after the flight was supposed to leave and they wouldn't let anyone on. Missed the first day of our honeymoon trip along with unrefundable hotel fees. I travel a lot and never had an experience like this before."
Pros: "I accidentally left my tablet behind when I disembarked. The crew located it and brought it to me speedily while I waited in the baggage area. I'm truly grateful and impressed. All of the flight crew were delightful and thoughtful."
Cons: "The flight from Vancouver to Seattle on the 31st of July was delayed by two and a half hours, the return flight on August 5 topped that by one hour resulting in a delay of more than three and a half hours and a missed connection flight to Port Hardy. I had to stay in Vancouver over night and my husband had to pick me up in Campbell River. This meant a car drive to and back Campbell River of six hours instead of one hour to Port Hardy."
Pros: "The flight was less than an hour. So I don't expect anything."
Pros: "Crew was great!"
Cons: "Why is there no TV?"
Pros: "NIL"
Cons: "40 min flight delayed for 1 and a half hours. Missed connecting flight. Staff was extremely rude to the hordes of people inquiring about missing their connecting flight, and were given different instructions."
Cons: "You"
Pros: "That the plane didn't crash."
Cons: "When I flew to Toronto the plane left 15 mins late but arrived an hour an twenty min late. No turbulence or trouble, just late. I stepped off that plane to my connector to Paris when boarding was suppose to start but that plane was on an hour delay. The food is just horrible, anyone who has flown knows this, and on both flights first class was the only priority. They got to everyone else when it was convenient. This was my first time flying with Air Canada and will certainly be my last. I'll happily pay a little more for the other airlines. So if you fly with them, good luck to you."
Pros: "New plane lots of comfort"
Cons: "Canadian airport very confusing got lost twice even with directions."
Pros: "Normal economy flying, you get a seat and line to the bathroom. I am thankful we are not traveling the old ways. I am over expecting too much when you don't pay much for it."
Cons: "Paid for breakfast but did not get it. However, I did not say anything to the attendant."
Pros: "Nothing"
Cons: "When I arrived in London my bag was not on carousel. I went to help desk to find out my bag was put on the next flight for some reason. No explanation given and no real accommodation given except telling when the flight would arrive. I guess I luckily only had to wait an hour, however it shouldn't be that way to begin with."
Pros: "I never could take this flight as Air Canada, with its unwelcome policy, needs a transit visa to change flights in Toronto. The sad part is, vayama and Air Canda (mis-spelled on purpose - deserves even less respect) do not even offer a partial credit if I want to cancel. Never am I going to use any of these or perhaps visit a bass-ackwards country like canada"

Never am I going to use any of these or perhaps visit a bass-ackwards country like canada"
Pros: "Air Canada has the best food, most leg room for economy class and super efficient. I will be using Air Canada often in the future."
Cons: "Delayed for almost 2 hours but keep saying just 50 minutes late"
Pros: "standard short hop flight"
Cons: "Check in was ridiculous. I went through al the on line procedures and was even able to print out my luggage tag at the kiosk... but then had to wait in line for 45 minutes just to drop my luggage! I came more than 2 hours before as instructed, but the agent at the "baggage drop off" (really the all-round agent for both checking in and baggage drop off) did not show up until less than 90 minutes before the flight, and then there was only one to handle what had become a very long line."
Pros: "Price"
Cons: "I booked a seat to be seated right next to SO. However, upon check-in, they changed the seat without telling me. Fortunately, we were able to exchange seat to be seated together."
Cons: "ran out of the food i wanted. poor selection of food... screen on "tv" was too dark to see details"
Pros: "Nice, normal flight."
Cons: "Pilots not there on time, arrived perhaps 30 minutes late, didn’t say why."
Pros: "No complaints about the flight or the crew."
Cons: "Delayed repeatedly. 3 hours behind schedule and no clear explanation was offered."
Cons: "All went well."
Pros: "The crew did a great job."
Cons: "Food!!!"
Cons: "Almost a 5 hr flight and there was no food or snacks given and water by request only. It was a full flight and the crew had just an attitude. Never had a flight like this one before. Horrible just horrible"
Pros: "Staff was professional"
Cons: "Flight was delayed 50 minutes"
Pros: "Seat was comfortable but little leg room."
Cons: "Difficult to find outlets between seats."
Pros: "Cabin crew was very efficient and polite"
Cons: "Baggage folks were not helpful towards anyone. There were a lot of problems and the agents seem to just ignored most everyone."
Cons: "Lost bags and every time I called to find out where they were I would get a different story. I was told it would be on the next flight for the next 5 flights."
Pros: "at check in - check baggage was quickly serviced"
Pros: "Gates for connecting were close and even with delay, I made it on time."
Cons: "Flight delay, that made the short connection even shorter"
Pros: "Poor internet going. No internet or streaming returning."
Cons: "Poor internet going. No internet or streaming returning."
Cons: "Gate crew didn't help much with seating or connecting flights. Staff almost never smiled, and when boarding the plane instead of a, "hello" or "good morning", there were two attendants staring at their phones. They looked up when I greeted first, but seemed put off a touch. They also switched the seating without telling us ahead of time, so my husband and I had to sit in middle seats, apart from each other on our anniversary trip. Very unhelpful and unfriendly when I inquired to change."
Pros: "On time, courtesy"
Cons: "Seating space, cramped"
Pros: "They had blankets waiting on our seats for us, which was really nice!"
Cons: "The seats were horribly uncomfortable and hardly budged when "reclined". It made for a miserable red eye experience."
Pros: "Quick and friendly staff"
Cons: "Uncomfortable seating"
Cons: "No leg room very uncomfortable seating"
Cons: "Great flight"
Pros: "Not anything in particular, this was a pretty aweful flight. They at least gave out connection flight information and told passengers which flights would be missed and set those people up in hotels."
Cons: "Plane was fully boarded and as the crew was preparing the cabin, the pilot realized there was a mechanical issue. An hour and half of sitting on the plane with few updates and grumpy people and crew, air being turned on and off as they fixed the issue and no indication when we would actually take off. They should have offered some water and snacks at least and gave more frequent and better updates."
Cons: "Now Sherry in any documentation I received did it say that my flight was operated by United airlines. I waited at ANA check in until within the 2 hour window and went around and asked someone at United who confirmed that they were partners with ANA."
Pros: "View"
Cons: "Over an hour delay"
Cons: "The seating was the worst I've ever had in my life and I've traveled my whole life. After I finish this trip I will never take United again. Everything else was wonderful"
Cons: "The flight was canceled because of the weather and then I have to wait more hours in the airport for the next flight.."
Pros: "Smooth flight"
Cons: "No problems"
Cons: "flight control forced us to miss my connection to Kansas City so had to spend $150 on a hotel in San Francisco and wait an entire day to get home."
Pros: "This new ticket where you have basic economy and pay for everything is ridiculous. You can't take a high end airlines and make it a basic economy people don't like that. Is this the worse version of Spirit airlines?"
Cons: "Just feels Cheap. Baggage claim took forever"
Cons: "The seats and headrests in particular were most uncomfortable for a 4+ hour flight. I was most uncomfortable on the flight and ended up with a pain in the neck!"
Cons: "Delayed getting on our way I think because they were late getting in and had to do all the plane checking. Captain said safety checks. Seat space felt tight and I am short."
Cons: "One of the crew members was late to arrive, so boarding was delayed. However, The gate crew was amazing, very communicative and apologetic. During the flight the attendants seemed very agitated, I think a smile would go along way to improve the attitude of everyone. I also work with the public, I get that it is challenging, but I do believe that the simple gesture of a smile sets the tone."
Pros: "The flight"
Cons: "The time"
Cons: "The fact that I was stranded in Colorado due to weather and they would not refund my ticket even though I had purchased insurance. They wouldn't even give me a credit. Will have to think twice about doing business through KAYAK and United from now on."
Pros: "The flight attendants were nice and helpful"
Cons: "Got a migraine because two ladies sprayed perfume"
Pros: "When it was over."
Cons: "Had to wait, probably 5 minutes, while holding my bags right outside the plane for an employee to do something. The attendants were unfriendly, unknowledgeable, and not available. Crammed 3 of us in the seat before emergency exit row seats, about 1" from my knee to back of seat in front of me and a 90 degree angle back, although there were many, many rows with only 1 person in them. One woman had enough room to stretch out and sleep across all 3 seats. Our seats didn't recline but the row in front of us did which made it even more cramped. Tried to ask attendant to move but couldn't find one for over an hour. Tried to ask an attendant but he just walked by me. Pushed call button and he says oh you want to move? There's​ a seat over here, before I could see where, he walked away. Moved myself to a row with 1 other person who was angry she now had to share "her" 3 seats. She typed angrily all flight and kept putting her legs and personal items as close to me as possible. She used both trays to hold her laptop and spread herself out so I'd be uncomfortable. Could've been prevented if the attendant had talked to the woman first then moved me. Had to wait when getting my drink because the attendant turned to help others, 4 times, after she'd already asked me what I wanted. She got food for someone while I waited. She made change for someone while I waited. She walked away to do something for someone while I waited. She served someone else while I waited. Asked attendant where the electric plug in was and she said the plane didn't have one, I said the sticker says the plane does, she walked away. Worst experience ever. Won't fly this airline again because of this experience."
Pros: "Comfortable seats. Easy connection to movies."
Cons: "Nothing"
Pros: "Nothing"
Cons: "Will NEVER fly United again. Going home to advise EVERYONE I know not to fly United. They straight suck. Starving people on long flights with hot food for a third of the plane?!?!?! Then telling me I'm wrong for expecting a meal on an almost 7 hour flight?!?!?! &, even better, the reason my son & I starved all morning, day , & evening because EVERY single flight (all 3) were late, one so much so that we almost missed the connecting flight. Wow, is all I can say. After I still have United a chance after assaulting that poor man. Beyond highly disappointed."
Pros: "The flight was smooth"
Cons: "The air hosts were in friendly and didn't say goodbye. The cabin was improperly pressurized and hurt my ears going up and landing. My ear is still popping."
Pros: "Good flight and good crew."
Pros: "Boeing planes are very comfortable. No pressure Really nice experience"
Pros: "Crew was nice, competent and amicable"
Cons: "seats were uncomfortable,ended up with back pain"
Pros: "Nothing"
Cons: "Customer service at united was rude on all ends phone and counter. Plane was delayed five different times and delayed for both flights. still at airport actually waiting on plane to take off when it was suppose to at 834 pm now it's 1142 pm so three hours later. I don't know who is running united airlines but it's a joke and should be shut down. There is so many people upset right now, horrible airlines."
Pros: "The crew was nice. That's about the only nice thing I can say."
Cons: "First of the seats are awful. Paying for the upgrade is hardly worth it. I'm sure first class is nice but the standard and business are not. Secondly the entertainment is a joke. You have to pay for everything. Only one flight had the TV sets on the back of the seats. The rest were paying for wifi and using your device. I bought the wifi and then it wouldn't work. It was a big waste of $10.00. Thirdly while I know the airline can't do anything about the weather, but they should schedule their flights with more of a layover. I was stuck in the air due to a storm for an hour and my layover was only for an hour. Luckily I was able to make the flight as they were closing the door. All in all just a bad experience."
Pros: "Fast clean boarding and unboarding."
Cons: "Missed the fact that I selected a red eye flight with a three an a half layover"
Pros: "Flight attendants were good. Pilot kept folks updated when there was an initial delay."
Cons: "Seats on United seem to be even smaller than other carriers. I'm 5'5'' and 110 lbs and I was still quite cramped."
Pros: "Good flight, good crew"
Cons: "People in group 5 don't have a chance to get their carry in bags in the over head storage."
Pros: "Typical flight. Crew was fine, nothing great or memorable. Free movies on devices are nice - although it would be nice for gate agents to mention it prior to boarding so guests without cell service could download the app on the airports wireless prior to boarding if they didn't already have it."
Pros: "My other passengers in First Class. Your crew was also very kind and well mannered."
Cons: "I spent over 150 for an upgrade for a red eye for a flight I already spent over 500. Your crew lacked attention in service and one specific crew member (male) woke me up twice due to the loudness of his voice. Disappointed in the quality for the amount spent."
Pros: "I'm never traveling with United again."
Pros: "overall the trip was pleasant, i dont like my 1 carryon be selected to not go in the overhead when groups like couples or families get to take on a few - but i did receive my carryon in a timely fashion considering we were not let off board after 15 min of landing"
