Airline reviews
Pros: "The move choices were good. The food and wine options were decent."
Cons: "The boarding process was confusing. Once boarding began, there was no attention paid to distancing guidelines. I heard the crew make announcements about mask requirements but never saw anyone being directly reprimanded or corrected for not wearing a mask or not covering their nose while boarding or walking around the cabin. Even though I only counted fewer than 20 passengers for over 100 seats, upon boarding, three solo passengers were assigned to sit in adjacent seats, with me in the row directly in front of them and another passenger in the row directly behind them. There was no precaution to space out passengers whatsoever. I had tried to choose my seating during check in but the online app was difficult to understand what seats were actually open or taken. Once I boarded it was clear the online information was incorrect. With so few passengers, the gate crew could easily have taken the time to review seating and re-seated customers for improved health and safety. This was my first time flying during COVID and I had thought airlines were doing more to instill trust in customers to keep customers flying but I will not be flying again until COVID is over as I did not see precautions keeping customers safe."

Cons: "None for now."
Cons: "Too warm in the cabin"
Pros: "Amy was absolutely amazing! She was attentive, knowledgeable, and friendly! One of the best flight attendants l have ever met."
Cons: "Seat didn’t recline..."
Cons: "Seats are thin so 9 hrs sitting becomes a pai in th b... Litterly. Both out bound and in bound the audio did not work well out bound not at all so 9 hrs not top notch"
Cons: "Daylight savings. Wrong time. Missed flight. $450 to rebook new one-way. What a nightmare!"
Cons: "The configuration of seating in business class allows for no privacy and my connecting flight just had food and front seats for business class. Our three across seats were the same as everyone else."
Pros: "Actually was British Airways and not another airline. Service was great."
Pros: "Despite all the “delays” it actually arrived on time."
Cons: "First it was on time (this morning t-12 hrs) Then it was delayed (delayed incoming flight) Then the plane changed and was on time Then something weird happend, departure was on time, arrival was delayed by 2 hours. Of course, officially there was no delay as departure was still on schedule - but “departure” just means everyone is boarded and plane door is shut, you could still be sitting on an empty stand on the tarmac for two+ hours. Complaints ensued. Captain rerouted plane. Back on time. Arriving at LGW is ridiculous - only 3!!!! THREE! Border nazis manning passport desk for entire south terminal, there must have been at least 700 people queueing. So that delay of 1 hour plus still occurred just within the airport. #ThisIsBrexitBritain #BrokenBritain #PeopleJustDoNothing #NothingWorks #AlexCruzIsACunt"
Pros: "It was a short flight but everyone was proper and professional, as I like!"
Cons: "Nothing really"
Pros: "Nothing. Delayed. Waiting around a lot. No satisfactory explanation."
Cons: "Delays. Poor communication. Disappointment that you can now count on BA to be worse than just about all other airlines."
Cons: "Computers were working very slow on check in creating huge lines. We were not offered even a tap water for free on this flight."
Pros: "The food was good and there was a great movie selection."
Cons: "I felt like a sardine. The seats are very tiny and there are so many of them."
Pros: "Spacious. Great movies. Funny safety instructions."
Pros: "Boarding"
Cons: "Seats spacing, food"
Pros: "nice employees"
Cons: "for the second time on this flight, the onboard devise for credit cards would not accept mine. this is the same card i used to book the flight. i complained to british air last time but they obviously haven't fixed the problem. there seems to be a problem using american credit cards these flights. is is a problem because nothing is free. luck;y a flight attendant did feel bad about it and gave me a glass of water"
Pros: "It got me to where needed to get to. First flight in 12 months that wasn’t delayed."
Cons: "Poor value for money. The food & drink selection (that you have to pay for) is abysmal. UK Border is a joke, 20+ passport desks but only 2 are ever occupied, ePassport gate DOESNT work (won’t eork if you have kids). Zero f**ks given. #BrexitBritain #BrokenBritain"
Pros: "Clean plane; friendly crew..."
Cons: "BA charges for everything on the plane, even water!"
Pros: "Safe, comfort, reliable"
Cons: "Food was NOT good at all. Go with theBeef & Potatoes"
Pros: "The flight was pretty standard in most ways, nothing too great/too bad."
Cons: "The food service was horrible. After dinner service, that was it. I didnt see anyone in the aisles with water. But the worst was in the am (this was the Chicago to London flight) there was nothing offered before landing. My experience is that there is usually tea/coffee/a light snack. But not even water was offered. I have told this to a number of people to get their opinion. Everyone is surprised. On the flight from London to Lisbon, nothing but tap water was free."
Cons: "no air vents over seats"
Pros: "Pleasant and efficient"
Cons: "Flight delay - but that is not always under airline control."
Pros: "The seats were comfortable and roomy."
Pros: "Nothing. Not one redeeming thing to say. What a shame."
Cons: "Everything. Massive delay, but not that much as it was JUST before the threshold (by 5 minutes), cheats. Radio failure was the excuse, followed by crew change - yeah, right, not buying that one - more like radio was fine, but crew wanted to chip off work early and avoid last flight (common tactic for a demoralised/unionised workforce). Border is still broken at LGW. THIS is Broken Brexit Britain."
Pros: "The journey Bengaluru to London Heathrow was very comfortable with sufficient leg room. However the journey London Heathrow to San Diego was not comfortable. This is because the seats are so designed that the Seat mounts come in the way of stretching your legs. It is improperly designed which can be checked out with any expert in ergonomics."
Cons: "The flight was delayed and on the arrival we have to stay inside for sometime."
Cons: "The union bull"
Pros: "Everyone was very pleasant to deal with. And I even got upgraded"
Cons: "The crew didn't even offer me a drink or food for purchase The baggage allowance fees were ridiculous -- I hate to pay despite being executive status and when I called several times prior to flight there were not helpful and referred me to airport who charged me a lot of $$! I willl be writing a note to customer service. In addition they are cutting back I was told and closed the ticket counter in Faeo Portugal -- not flying them again"
Pros: "Very courteous staff. Food was good. Flight was fast. No problems."
Pros: "Everything"
Cons: "None"
Pros: "Good on time arrival for a no hassle connection."
Cons: "n/a"
Pros: "Flight was good"
Cons: "Easirent The car rental company that I got from kayak Total disaster waste of time did not end up taking the car I got an excellent rate and then they try to rip me off on the Insurance You should not do business with them"
Cons: "Not really friendly. Nothing to drink. My chair was broken so I couldn't really lean back."
Cons: "Plane was extremelly cold.Came back with bronchitis, missed day of work.Attendent claimed they do not have blankets, but at least came later one with one. Seat could have been broken was uncomfortabe sit on,"
Pros: "Well organized, taken care of for connecting flight when plane was delayed 2 hours."
Cons: "HEATHROW IS A NIGHTMARE, Not the fault of BA"
Pros: "Good inflight entertainment system"
Cons: "Somehow my seat wouldn't recline at all. Not great for an overnight trip costing close to $3000"
Pros: "Choppy Flight. Amazing Pilot"
Pros: "The crew were awesome-very polite, friendly and helpful! Food was also excellent."
Pros: "Boarded easily plenty of room for bags"
Cons: "All snacks and drinks cost money! Paid for extra legroom row but my knees still touched seat in front of me. Exceptionally poor aircraft configuration - business class had center seats blocked. Remove those rows and make business class 2x2 and I will consider buying it."
Pros: "There was nothing I liked!"
Cons: "I couldn't do online check in and was at the airport 2 hours before the flight but they said they cannot give me a seat number and waited there for 25 min to get a seat number. The seats were really uncomfortable (compared to airlines as Turkish airlines and American Airways).The flight attendants were not there to make your flight better, one of them was sulking and was afraid to smile to you but when he was with other crew was able to laugh! Also food was really bad!"
Pros: "Better seats and space"
Cons: "New M&S menu, makes service too slow and the items are mediocre."
Pros: "great selection of in flight entertainment."
Cons: "At JFK there was a long wait for the luggage, which ended up not being delivered to the carousel, after we had waited for almost 2 hours. Granted, there was some snow and some technical issue since the fire alarm system was flashing the whole time, but still, there were only two announcements made during that time, and the second one to let us know that we'd have to arrange for delivery of our luggage on the website. By that time, it was past 11;30pm and everyone was dead tired, when the flight had been supposed to land at 7:25pm. I think the blame is to be laid on the JFK installations. Everywhere I travel in Europe, airports are in brand new condition, and not only departure areas like in the US. No wonder baggage delivery was a mess after just a little snow/"
Pros: "The crew was great. The food was surprisingly good. The passengers were mostly British, a pleasant surprise considering (my fellow) Americans are such inconsiderate jerks."
Cons: "No place to charge cell phones. The entertainment choices were limited."
Cons: "Flight landed late and I had to catch another flight what was supposed to be a 13 hour trip turned into almost 24 hours. Very uncomftorable seating."
Pros: "on time, friendly staff, helpful with babies"
Cons: "less and less legroom on BA! think about tall people"
Pros: "Friendly crew! Comfortable seats...great food"
Pros: "Nothing."
Cons: "Nothing"
Cons: "A working ladder and door"
Pros: "Bought a seat 3 hours before check in and had a row to myself"
Cons: "Excellent Ryanair flight. 75% full. Very friendly crew."
Pros: "Nothing because I wasn’t allowed to board"
Cons: "Everything"
Cons: "It was late. Usual hearding us into pens like cattle . Hurry up and wait"
Pros: "good to have bag drop-off ,flight on time but an older plane"
Cons: "Queues at security at Manchester always a nightmare! .Foreign airports do not have that problem"
Pros: "Price"
Cons: "Better seats too tight"
Pros: "Great crew. :)"
Cons: "Landing a little bumpy this time but overall a good flight."
Cons: "On arrival at Dublin Airport we had to wait outside for a period while they arranged to open a door to enter the building"
Pros: "flight on time"
Cons: "priority passangers can board first, but must wait half an our standing up in the corridor. I do not understand this and what the advantage is. next time, I will wait in the chairs until the last ine, because you already have your seat number."
Pros: "Crew was helpful."
Cons: "On the check in process we fell force to pay for our seats, we bought the tickets (my wife and myself) in the same transaction and paid with the same card, the check in was made from the app, both at the same and they put us apart (row 6 and row 33) when in both cases were free seats next to us."
Cons: "Plane was late as most Ryanair flights in the afternoon are expected to be."
Pros: "While the movies choices were limited and the quality not that great, the price was not large either."
Pros: "It was short"
Cons: "Ryanair website and use of cookies is designed to confuse and extract as much money off what should be a simple process. At the point of booking after inputing card details the price went up £208 pounds. Removing cookies and rebooking was over £300 cheaper. There's so much more to say"
Cons: "Boarding"
Pros: "Safe journey and on-time"
Cons: "There are too many announcements, always advertising something or other, it is an invasion of the ears that cannot be ignored."
Pros: "The crew was kind and respectful."
Cons: "Ryanair hides a lot of hidden costs and inabilities through their site. I had to pay extra for the luggage that I didn't know about."
Pros: "The crew and the timeliness of the flight."
Cons: "The level of comfort. Pretty terrible airplane seats, but are tolerable if you’re doing a short flight."
Pros: "Quickness with the site. Easy to use"
Cons: "1) my first issue is that my card was charged 2x before having to run it a 3rd time to guarantee my flight. I guess Kayak and Ryanair do not communicate as easily as other carriers. 2) I was charged $50 Euro at the counter for NOT checking in. I attempted to check in numerous times, but it was not allowing me to check in. I received a booking confirmation, but never received a confirmation ID that would have allowed me to check in on the flight. I would appreciate if Kayak would have a response to this?"
Cons: "Late, dirty and not properly stocked..."
Pros: "Nothing"
Cons: "The landing was dangerous and rough."
Cons: "Booked 3 flights all on Ryanair for a trip inside Portugal. The booking agent, Gotogate.com, and Ryanair left me deserted. Some error occurred and I received the same flight booking # for all 3 the flights. I discovered this when trying to retrieve my boarding pass for the second flight. Neither company fixed the problem and I could not board the flight. I ended up having to rent a car and drive to Porto (6 hours away). Neither company have anyone that can assist with these issues on the weekend. The worst experience I could have had on my birthday vacation."
Cons: "We attempted to cancel our reservations more than a week before our trip because my husband was hospitalized. Not with the flu or a broken arm, but a major and serious life threatening illness we are still dealing with. We provided numerous documents as proof of the absolute dire situation and they denied the request over and over again. I get that the tickets were "non-refundable" but at least offer vouchers, credit, or be totally a stand-up company and refund the tickets. It wasn't buyers remorse, trust me, we would have preferred to be in Portugal, rather than sitting in a hospital hoping and praying for his recovery."
Pros: "You get what you pay for. No issues"
Cons: "The queue on the tarmac waiting to board but I realise they are trying to keep to schedule"
Pros: "Cheap cheap cheap!"
Cons: "I find it incredibly ridiculous that a flight is half full and I’m deliberately seated away from my husband just so Ryan Air can make an extra £4 per seat. I get that they want to make money but that’s pushing it too far. I sat next to someone who was also traveling with someone else. That lady’s companion came back and told her the seat next to her was empty. By then everyone was already settled in. Is it really worth the £8 for two people? I’m sorry but that’s just petty."
Pros: "The crew were all friendly and welcoming"
Cons: "Nothing"
Pros: "Great trip, right on time, plane was clean, colors are a little weird, guessing some one is a Michigan football fan"
Pros: "It got me home"
Cons: "Boarding was slow, seats not together unless you pay, uncomfortable seats, park up in poor location meaning you have to go up and down steps. Not good with push chair"
Pros: "Not alot,crew was pleasent and staff in London were lovely"
Cons: "Small seats, uncomfortable,over priced drinks and food terrible landing.delayed"
Pros: "The flight boarding was delayed by 45 mins originally, which was added 15 mins onto then half an hour when we were then we were all very badly moved to another area when I say very badly, we were given poor instructions and me and some other passengers almost ended up on the wring flight. After we finally got to where we were supposed to be half hour was said that came and gone then another 15 mins when we were moved back to boarding area. Another half hour finally got boarded then and after this was the usual great Ryanair experience."
Cons: "The flight boarding was delayed by 45 mins originally, which was added 15 mins onto then half an hour when we were then we were all very badly moved to another area when I say very badly, we were given poor instructions and me and some other passengers almost ended up on the wring flight. After we finally got to where we were supposed to be half hour was said that came and gone then another 15 mins when we were moved back to boarding area. Another half hour finally got boarded"
Pros: "Seat ok"
Cons: "Delay with no information.this is an airline that although cheap has no interest in customers"
Cons: "From Bournemouth to Faro and Family,when do you start again? Sincerely. J. Tavares"
Pros: "Nothing."
Cons: "Flight was an hour late without notice. I payed for selected seating and was not seated with my husband, I payed more for my luggage than the air fair, had to pay for water. Pushing for product sales. The most unrelaxing ride I have ever been on. And complicated checkin online."
Pros: "The helpful, friendly, happy crew. The fact you get a choice of food and the crew are not run off their feet serving everyone food that is included in the flight price. Very efficient shuttle bus service between airport and destinations, again with helpful and friendly staff."
Cons: "Cramped seating. High cost of booking hold luggage."
Pros: "There is a large lounge at the gate at Gatwick that the passengers could have been checked into prior to boarding commencing, but this was not used. Instead, A large queue was in place for over 40 minutes and once boarding commenced, as many were checking cabin bags into the hold, boarding took about 30 minutes, delaying the flight by 30 minutes"
Pros: "Nothing"
Cons: "Ryanair boarded the plane only for us to be stuck inside a dirty stinky tunnel with no plane at the end of it. Crying children, moaning kids, no air conditioning, for about 1.5 hours. Ryanair as a company KNEW they'd be delayed, yet they board us into a disgusting tunnel to sit on the floor with no toilets no water nothing. We then board but at this point I was deathly ill and Ryanair didn't take care of us at all with any free refreshments like they should have for being late. Disgusting service. Won't be flying with them ever again this happens way too often."
Pros: "We paid for our seats but the staff decided to move people that were separated due to Ryanairs booking system to move with us who had paid for seats. No good"
Pros: "Prompt take-off, good in-flight service, landed 30 minutes early."
Cons: "Had to pay 36 euros to get printed boarding passes."
Pros: "Very unorganized and discretion about what was a carry on bag differed. I was charged an extrodinary fee while others did not."
Pros: "I needed a glass of water as soon as I boarded to take some tablets as I was starting to feel unwell. The crew accommodated this immediately and were very pleasent."
Cons: "Why people don't just pay if they want to sit together. It is that way now so go with it rather than main and play chess on the plane, asking people if they will change seats. Sort it out your adults. Surely you can cope for a few hours?"
Cons: "My wife and I was split up and ended up in middle seats of different rows and neither of us had people to either side of us. This is Ryanair trying to get you to pay for guaranteed seating the next time you travel. Ridiculous!!"
Pros: "Sometimes this airline would offer good deal, even though the one I booked was just a normal price. And it's pretty clean and comfort too."
Cons: "A bunch of hidden charges after you paid the air ticket, including luggages and check-in fee.."
Pros: "On time flight"
Cons: "Walking through endless sales & loud music to get to airplane"
Pros: "Everything"
Pros: "Most of the crew were hard working, pleasant and the flight came in slightly early"
Cons: "There was a cabin services director (or whatever his title was) who clearly liked the sound of his own voice. He kept going on and on about how bad the weather was in London and how sunny it was in Portugal. He mentioned rain and snow in London and suggested that people booked a return flight to Portugal in the twenty-five minutes available to them in London after the plane had landed. One joke about the sun versus the rain might have been acceptable but to raise it again ad again just became irritating and an abuse of the PA system. He shouted Halleluja amongst other things when trying to get money out of people for the Ryanair charity. If he wants to be a professional comedian he should change his profession as he was just annoying people and he stopped the flight from being relaxing,"
Cons: "Flight delayed by 7 hours"
Pros: "Plane was late and no reason given until we were sitting on the plane."
Pros: "Speed of boarding"
Cons: "Ran out of tea and coffee after first 3-4 rows so most of us had none."
Pros: "Used rynair few times now easy to book great value"
Cons: "Cant say there was anything negative ."
Pros: "Not much"
Cons: "We were stuck on the plane for about 40 minutes after takeoff with no AC because they couldn't start the engines? I am not really sure if that was the reason they gave us zero communication..."
