Pros: "Crew was amazing, someone had found my passport and turned it in to a crew member."
Cons: "Nothing"
Pros: "Check in was a breeze with all so helpful. Cabin crew very pleasant. Very comfortable on time flight."
Cons: "2 hour delay on an hour flight"
Pros: "When I finally settled into my seat on the British Airline and that Hostess came around and offered me a couple of free drinks that was the best thing that happened to me all day."
Cons: "For an older couple like us did not like having to climb the steps up into the Plane and being out in the rain did not help. However that was not the worst part of the arrangement between getting off the Aer Lingus plane and with so little time to reach the gate for our BA flight to Denver it was a total disaster. Due to a minor problem my wife had with her foot I had asked for a wheel-chair to be available when we got off the plane at Heatrow. Good job that I did because with out their help we would never have made it in time for your flight to Denver. Between up and down in elevators, running along the corridors, in and out of a bus and I myself trying to catch up with those poor attendants. I was sorry that I did not get a second wheel chair for my self. Only for the flight was delayed by about 20 minutes we would have missed the flight. Who ever was responsible for making the arrangements of just allowing a time of 1 hour and 10 minutes between flights needs to figure out a better time schedule before people of our age ends up getting stressed out and end up with a heart attack. Very stressful indeed, believe I will never let this happen to me again. Fly/Us you need to fix this."

Pros: "took off early once they had accounted for everyone, and arrived a little early too."
Cons: "While I didn't have to check my bag on the first longer flight, I did have to check it on the connecting flight which delayed me somewhat in getting into the city of London. Not awful, but strange... Free-for-all when boarding, not nearly as organized as it was at JFK."
Pros: "The efficient flight but no drinks or snacks w/o purchase"
Cons: "Paying for inflight drinks. All US airlines provide FREE complimentary drinks and snacks. Seemed in poor taste to charge for such things made the airlines appear cheap."

Cons: "check-in desk couldn't check me through to my connecting flight with Virgin Atlantic so I had 15mins once landed in Heathrow to get through passport security and checkin at Virgin Atlantic desk.... I'm young and fit so was able for the dash but elderly or familys would not have made the connecting flight in that time"
Cons: "Paying for beverages seemed a bit much."
Cons: "Bags got delayed by a day."

Pros: "Crew, speed, ease of security at Cork"
Cons: "The lady in 1C who turned her phone on as soon as we hit the British coast"
Pros: "Crew polite. Seats comfy."
Cons: "One person checking boarding cards at gate led to a ridiculously long queue for a nearly full flight and made it late getting us all on the plane and passengers were getting annoyed. Then whatever machinery Aer Lingus use to push the plane back from the gate actually got stuck on the plane cone leading to another delay. Knock on was we were made to wait for a take off slot and made to wait for a landing slot at Heathrow so late arriving."
Pros: "Reilly dolly"
Cons: "The other trolley dolly"
Pros: "Loved being on a flight for holiday, and knowing I wasn't being overcharged for needless frills."
Cons: "I don't remember if they served a drink, I know things were for sale. But that seems to be the European way."
Pros: "The British Airways portion was exceptional! The Aer Lingus portion was not!"
Cons: "On Departure for Dublin, waited in long line to check in at Aer Lingus only to learn it was co chaired by British Airways, so Aer Lingus would not service us at all. We had no way of knowing since it was sold by Aer Lingus and had an Aer Lingus flight number. Tried to check in on line, but was unable. Waited for Aer Lingus customer service on telephone customer service for more than one hour and finally just gave up. Aer Lingus has no Customer Service at all. Do not deal with Aer Lingus under any circumstances. British Airways met our needs!!"
Pros: "We left on time and landed a bit early. Only 1 1/2 hour flight, so no food, drink or service, but it got us there."
Pros: "The personnel involved with wheelchair services who took us to our gate was very helpful and engaging. We thank them for this service. The gate personnel and flight attendants were helpful to get us on the flight earlier that was helpful with my husband" visual disability."
Pros: "Efficient staff and timely I would book again for sure"
Pros: "We landed safely."
Cons: "Mobile check-in not an option. Seats not available until check-in without paying. Nothing is complimentary on a rather expensive flight."
Pros: "Crew was friendly. Boarding was efficient."
Cons: "Hard landing."
Pros: "Comfortable Clean"
Cons: "Food/drinks a little expensive"
Pros: "Our return trip from Shannon to JFK was the best flying experience we have ever had. I requested an aisle seat for my 6'5" husband and we were given the emergency aisle. The flight crew was outstanding- Ashley and Hazel could not have been nicer to us. My TV set was broken in my seat but I did not care as I had a lot of reading to do. It was an outstanding return trip from a wonderful time in Ireland"
Cons: "Very uncomfortable!"
Pros: "Very polite and helpful."
Cons: "Unknown"
Pros: "The planes were comfortable and the online and airport check-in process goes smoothly."
Cons: "Not even water is available to passengers. And flight attendants must shill to SELL food perfumes and merchandise during the entire flight. It seemed very unseemly that professional flight attendants were forced to behave in such an unprofessional manner. Sell, sell, sell is their job on Aer Lingus."
Pros: "We were late for our connecting flight because of a plane issue and no one from the Air Lingus did anything to help us get to our next flight out of London to Munich. We asked several times and they said follow the signs ."
Cons: "We were delayed by 2 hours and we missed our connecting to Bangkok from London. Which resulted in queuing with two small children for 4.5hours then we luckily were given a hotel, but we missed a day of our Thailand holiday."
Pros: "Nice crew"
Cons: "I booked my flight in March (for travel this June) to make sure I got a window or aisle seat. When I checked in (on this flight and on my flights to Dublin) my seat had been changed to a middle seat, and there was no way I could change it back. Also, I was not able to check-in online the night before, like I have been able to do on some other flights in the past."
Pros: "From the ticket counter rep to the flight attendants, everything about this airline represents professionalism and excellent customer service."
Cons: "Nothing."
Pros: "Friendly efficient service and complimentary late flight snacks with beverages a nice touch you don't get on other transatlantic flights"

Everything was great

You have to pay for food; disembarking was super long

Aircraft was late, then back to on time, then late again. Food is just a cereal bar and water. For 200 euros.

Pros: "Nothing it was delayed by over an hour and there was ZERO on ground or in air rebooking support or information at all! Ground crew were useless and rude. No one was there to navigate us through a delay that you all caused. We were traveling with 5 children and there was zero sense of urgency. We missed our connecting flight as a result as did the 100+ other passengers on this flight. How could BA not notify it’s partner AA to delay the connecting transatlantic flight as a result of its 1hr long delays? Horrid!"

How could BA not notify it’s partner AA to delay the connecting transatlantic flight as a result of its 1hr long delays? Horrid!"
Pros: "The people from British airways were incredibly helpful."
Cons: "British airways pushed the flight time which made the original connection flight from Heathrow impossible. They notified justfly the company who we used to book the flight and told them the reservation would be cancelled. Only justfly never did something about that. They did not notify us about any changes and when we arrived at the airport the lady at the counter told us we don't have a reservation even though justfly happily took our money. If it weren't for the BA staff who rebooked is through Air France we probably wouldn't have made it."
Pros: "The BA staff on the plane were excellent, given the horrible way we arrived to board the plane. They went above and beyond to help mitigate the treatment before boarding the plane. Also, our vegan that we requested via American Airlines on the phone back in September didn't appear on their list, so they made the best out of a bad situation."
Cons: "Our first BA flight was late leaving and therefore we arrived to our 2nd flight 20 minutes before the flight was to leave. The check-in staff were completely rude, telling us to run and threatening to not let us on the plane. It was not our fault the plane left late from BCN to LHR. Once we were actually let on the plane, we didn't push back from the gate until 5-10 minutes after the scheduled departure time. There was absolutely no reason to have treated us that way, so we promptly submitted a complaint to British Airways."
Pros: "Comfort, friendly staff"
Cons: "Paying for food and drinks"
Pros: "Nice aircraft! Very modern."
Pros: "Not much. Eventually got to where we were going."
Cons: "I can't remember a more cramped and uncomfortable flight. Missed connection on way Paris and we arrived 6 hours late. It took British airways 3 days to get our lost luggage to us. Delayed on way back, adding 4 hours to our trip because the first plane was not "serviceable" and they had to get a replacement. They arbitrarily decide who has to much carry on luggage and force you to check it last minute at the gate while letting others with same size bags take them on the plane. Certainly no better than bargain flights and possibly worse. Why pay extra? No more British Airways for us."
Pros: "Sort of on time"
Cons: "Buy on board menu poor Both sandwiches contained cheese Of the meat dishes all except one containing pork No indication of halal dishes Also several nut dishes The of the four confectionary offerings, three contained chocolate"
Pros: "Courteous and friendly staff"
Cons: "Outdated ife and unpleasant buzzing noise from the headphones"
Pros: "Efficient processes. All went to plan"
Cons: "Tight seating. Old plane. Entertainment screen sub par"
Cons: "The plane was actually about to fly off when it suddenly skidded to a stop. We weren't informed about the reason, but all of a sudden, the plane couldn't take off for over two hours. My family and I ended up missing our connecting flight home. BA tried compensating with food vouchers and rebooking us onto another flight, but our family got split up in the process and we were all assigned to different middle seats."
Pros: "Nice crew"
Pros: "Wine fantastic, crew fantastic, comfortable seats in biz on A380. Food selection diabolical"
Cons: "Food was awgul"
Pros: "Not much"
Cons: "Food was horrible"
Cons: "We had a carry on and were flying business class. They made us check in the bag but it was clear that it could fit. They said it was a busy flight so we had to give our bag up to check in. We arrived on the plane and there was plenty of space to put our luggage. It was not a friendly experience especially paying the premium to fly business. They were very direct and non forgiving. Crew on board were nice though!"
Pros: "comfort is really good the seats are big"
Cons: "nothing"
Pros: "Polite staff professional"
Cons: "Delay."
Pros: "Plane had to be de-iced which delayed departure time and then wait for landing slot."
Cons: "Heathrow need to build more capacity to reduce emissions and delays."
Pros: "Staff were great, classy even, making the journey pleasant"
Cons: "On checking in I wasn’t given the option to add a bag, meaning I had to pay over double the rate at the airport. Trying to add one online or on the app failed. Calling the support helpline was a waste of time and money; spending 10mins on hold before being told there was nothing to be done."
Pros: "The flight went really easy and smooth. The cabin crew was very efficient doesn't disturb you during the fligh with sales therefore you can focus on your things."
Pros: "On time"
Cons: "Group of men walked about and talked to each other rather than sitting in their seats."
Pros: "How efficient, professional and pleasant the captain As well as cabin crew were."
Pros: "Great crew members and boarding was immaculate."
Cons: "Good flight, however I could see that not only my children were bored after an hour into the flight. Entertainment would be beneficial for BA to introduce asap."
Pros: "The crew was very polite and friendly, making this 7-hour flight enjoyable."
Cons: "There was nothing I disliked."
Pros: "Certainly not the female airline attendant from Johannesburg to London on 1/4/2018."
Cons: "I boarded the plane and made a mistake by sitting in the wrong seat and placed my hang-up bag in the overhead compartment. When I realized that my actual seat was 10 rows back on the very last row, I moved, leaving my hang-up bag near the first seat. As time passed, I heard a woman on the intercom say something about a lost "jumper". After learning that a "jumper" is a sweater, I asked the nearby airline attendant if the sweater was a navy color, like the one that I had left in the overhead. A female airline attendant came to me, carrying my hang-up bag with my sweater and repeated 4 times that I was lucky because she was about to put my "jumper" and hangup-bag off the plane and leave it in Johannesburg since no one had responded sooner!!!! I was so stunned that I could not say anything. I only kept wondering why would anyone go into the overhead and start pulling things out? Why would someone take such extreme measures and not walk down the aisle, asking every person on the plane, including the people on the back row? This type of thing could happen to anyone. Since I did not have a name tag on the bag and I live in the US, it would have been near impossible to ever find my bag again if left in So.Africa! Plus, the woman went on and on in a very rude & condescending manor when all I could do was sit in shock, wondering why she would take the time to go through the overhead and look for a hang-up bag that does not have a name tag!!!!"
Pros: "Nothing"
Cons: "Everything"
Pros: "Crew were good , food was ok."
Cons: "Flight delayed again so both flights to USA and return were delayed... not a great experience . Entertainment took a cou0le of hours to sort, they had to keep resetting it"
Pros: "Excellent flight. Staff very helpful and professional."
Pros: "Pleasant staff, trying to put a brave face on standards they know are slipping"
Cons: "No breakfast, no snacks, tired seats, poor entertainment , dreadful food (and I LOVE airline food!)"
Cons: "I paid 100$ because I had to cancel my request. It was a technical error of your reservation system which unexpectedly changed my return from the 5th of November to the 6th of November. The fine was unfair and you're required to refund me."
Pros: "Crew, funny safety instructions with Gordon Ramsey"
Cons: "Delays"
Pros: "Bigger plane than I was expecting. Had I known that I would have upgraded to a better seat. I was just expecting a tiny puddle jumper so this was a nice surprise. Crew were nice, offered food/drinks but I didn't want to buy any."
Cons: "The plane had inseat screens but they said that licensing agreements prevented them from offering any video, games or news selections on a 2.5hr flight. The Pilot said he would turn on the in-flight navigator but it never did work, so I'm not sure what happened there. No internet connection in their fleet yet either. Clearly, this is a first world problem and I would still fly BA. But it's also 2017 and these features aren't "new"; I remember having in-flight entertainment back in the early 2000's on Delta flights in the US, so I'm not sure why it's taking more premium airlines so long to catch up."
Pros: "British Airways rescheduled our flights. The BA website was easy to find out how to claim additional costs incurred from the rescheduled flight."
Cons: "The flight was rescheduled within 18 hours of departure. We were in Spain on vacation which meant attempting to figure out how to get home with Iberia at the Madrid airport, who helped but was super agitated with us the entire time. When we asked for advice on how to proceed, as this has never happened to us before, they just kept telling us it was British Airways fault and that they had no answers for us. This took about two hours plus an additional hour back at the hotel to cancel our reservations in London and figure out how we were going to get reimbursed for the extra night at the hotel and additional costs. It would've been nice to get all of this information in an email, with the new ticket and instructions on how to claim the extra costs instead of us running around and taking time out of our vacation."
Pros: "I liked arriving safely at my destination despite a delay due to atc strike. Thank you BA pilots for doing a great job. Not to mention politely letting passengers come view the flight deck during the delay to ease the boredom."
Cons: "When kindly asked a question by me, one of the staff didn't understand and instead kept insisting we didn't need a landing card (we did). Tried to rephrase the question and she persisted without trying to understand, rolling her eyes and swearing under her breath. Oh, and did I mention the part where we had to pay for our checked bags again? 75€ per bag. For me and my wife, that's the equivalent of a third ticket for our flight. May as well had our luggage fly next to us. So rude staff and exorbitant pricing for things that somehow weren't logged through third party. Cheers! (Sarcasm)"
Pros: "I had purchased an upgrade to economy plus --- it was great--- much more expensive than I had thought, but I was tired and wanted to try to rest. There I was greeted with champagne, a warm wash cloth and fabulous service by the two male crew members!!! Truly the best! I am almost 70 and I wear hearing aids--- one helped me with my chair and answered my questions .... I felt VERY taken care of/- I was just one row after the business class with the wall ahead on right side of plane, nice leg room and a nice seat mate I am happy for the chance to respond as I was happy I had decided for the upgrade------------even though I had purchased an upgrade for my flight over to Barcelona only to find out on the day of check in that my flight was cancelled----- but that is when I called British Air and a lovely representative named Beth Duncan spent over 2 hours on the phone with me---- finally getting me on Iberia in order to get to my family reunion------ So....... on two occasions during this trip to my sister's house British Air was just wonderful and I thank you very much------- at the end of our flight one of the men made arrangements for me to get to go upstairs and look at the upper deck as I had never done that before------- as as retired teacher that was fun to see Thank you so much!!!"
Cons: "The woman who worked the British Airways desk in Helsinki and checked our bags is not suited for a customer service position. The screens on the British Airways long haul planes are tiny and difficult to operate. A 2,5 h flight where you can't even get water complimentary is appalling. Honestly all of your competitors offer a snack and beverages complimentary even if the flight is only 45 min. The boarding for London to Dallas flight was very confusing and could have been made easier with grouping the boarding instead of tons of people piling up to rush in at once."
Cons: "Leg room/space BA offers is calculated for short and small body frame passengers and it is on not acceptable. It feels like cattle Wagon. BA should show consideration for real passengers not some sort of statistical average. I am 6'4" and sitting in your plane's cabin inflicts hours of body pain. The space given is sufficient for children and teenagers. Also sitting in the hot cabin for extended amount of time is extremely uncomfortable. Why there is no cooling and proper air ventilation right from the beginning?"
Cons: "The check-in personnel refused to allow us to check bags until 90 minutes before the flight, then delayed that time three more times. This caused a real scene with nearly one hundred people standing around the check-in counter waiting to put their bags on the conveyor belts. The flight, which was delayed multiple times--once due to the ground personnel at Orly not turning in the paperwork for the flight--eventually took off, but the cabin crew seemed confused the whole time. We asked for Landing Cards, but they told us we did not need them, when in fact we did. That extra delay at immigration caused us to miss our connecting flight! Since half of the plane was connecting in Heathrow, why didn't the crew suggest that those staying in London wait on the plane until the connectors had a chance to disembark?"
Pros: "Checking in online 24 hours prior to departure I received up-dates thrice regarding the delay of the flight which was very convenient. I had also learned about the protections that I enjoy as a passenger checking in online. The flight caught up in terms of timing as I had to catch a connecting flight to the continent from London. I was very pleased, also with the courteous flight attendents, the food, the entertainment selection and sufficient leg room in economy class. Overall a lovely experience, indeed!"
Pros: "I require a wheelchair for getting around the airport. When I first checked in at LHR, they claimed to have no record of my wheelchair request and my seat change, despite my very clear notations of who and when these were made. They did have a record of my paying for one suitcase. The agent at LHR promised to make these corrections so I would not have the same problem when returning to London. Furthermore, to turn this into a humiliating situation, at the gate I was informed that the jetway was broken and they would have to find some other way to get me onboard the plane. I cannot believe that British Airways has no contingency plan for a situation like mine. After many discussions between BA reps and ground crewmen they decided to bring me down in a lift at Gate 34, though my plane was at Gate 32. I was then loaded onto the freight platform of one of those food delivery trucks and driven over to my plane. The truck backed into place and again I hoisted up to the plane. However the plane door was locked and we had to bang on it for them to finally open it. To my great embarrassment I helped down the aisle to my assigned seat, looking back at the curious looks and glares from all those passengers who had no explanation for the delay and humiliating scene. Officially the flight was listed at 28 minutes late, when in reality it was 40 minutes till we taxied away from the gate My return flight from Brussels was little better because the changes that were supposed to have been entered at LHR never were and so I had to go through this whole routine again costing me over one hour in delays. Fortunately I was able to board the flight through the jetway and did not have to be hoisted up again, and delivered like freight. How would you rate these flights. I had problems with every single British Airways flight!!"
Pros: "The check-in process at the airport in Chicago was efficient and the person who helped us was friendly"
Cons: "-I was unable to check-in online and I think it's because my name got messed up in the reservation system even though I entered it correctly -Compared to other airlines, BA does not stop by frequently to offer beverages. Food and beverage service provided by BA faded in comparison to what was provided by American Airlines on the way back. - Our flight was delayed due to weather, but we also sat in the plane for a long period of time with no explanation. -We appreciated that BA automatically re-booked us on another flight (although it was not the next flight), and provided 2 meal tickets for 10 euro each. There was no other compensation for the incurred delay (about 2.5 hours)"
Pros: "Entertainment system"
Cons: "The width of the seats in economy are so narrow they don't fit my back. I am not a fat person. 6 feet 170 lbs and fit. No legroom and the tray table is not deep enough to support the food tray. Breakfast after an 8 hour flight consisted of a Kellogg's snack bar in a wrapper. I am used to Southwest Airlines which allows more than one peanut bag so I took two breakfast bars and the stewardess scolded me and said only one and made me return my extra. Not everyone in my roll even took a bar. They treat you like dirt in coach."
Cons: "Crew was not helpful at the end of the flight when we had a very short turnaround time due to delay and my girlfriend had to run to catch the other flight and she has recently had hip surgery. The crew was asked 3 times for help and their response was "you will be fine". We were not fine also the security crew at Heathrow was incredibly slow and there were 3 standing around talking and one very slow very rude lady going through bags which caused us also to be delayed and have to run to catch connecting flight to SF just barely made it - totally unacceptable."
Cons: "We arrived at the airport more than 2 hours in advance since this was an international flight. There was NO British Airways staff available to help with obtaining actual boarding passes which were NOT available on the BA mobile app. Although we made the flight with enough time, that was only because the security line was short and the passport control line was short as well. British Airways should have staff available to process passengers and boarding passes, luggage checkin, etc. earlier for their flights."
Cons: "The flight time change (one hour later of etd) one week before has not been motivated. It has been only 2 / 1 day before. The change of policy of food onboard.....flight tiockets especially with ba are not cheap and onboard you have to pay for everything!!! only tap water is free....incredible!"
Pros: "Crew was fantastic, food and drinks were of a very decent standard."
Cons: "Boarding was in a cramped corner so a bit confusing, no enetertainment at all on a (very) old plane."
Pros: "Inflight crew was good and polite."
Cons: "Made me go in economy class que to enter the aircraft inspite of I having paid the 3 times more expensive business class ticket. Business class seats were too small and uncomfortable compared to the other airlines. Loos and facilities were not in accordance compared to the other airlines."
Pros: "The staff are always pretty good. On the Japanese side side they were brilliant."
Cons: "The flight out out was 40 minutes late leaving and the return flight was an hour late getting off the ground."
