Airline reviews

Pretty bad. Food was awful. drinks were scarce, as if drinking an extra drink would ruin the airline. attendants were not very helpful. likely Dutch "directedness" (I cannot be bothered). Crammed flight. Entertainment in very minimal dosage. Almost all old movies and series with 1-3 episodes only. Very limited number of options available. Jesus!! it seems you need to bring your own entertainment these days even of flights that are 13 hrs long!! I would and I will avoid in the future!

The flight was again delayed for more then 2 hours with some lousy explanation regarding the reason of the delay. Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

Seats are fair enough for medium tall people. Good food all the trip. Fight attendances are warm

I thought KLM was the best airline but the Lima - Amsterdam was 1 hours late, the Brussels - Amsterdam was 2.30 hours late and the Amsterdam - Lima was 30 minutes late

no issues at all... Kudos to the food. This time was really really good

The food was ok. The crew seemed like they were cranky. I had one guy get mad at me for passing in between the storage area to get to the other toilet. I can understand if it's not allowed but reprimanding me like I'm a student saying "This is the last time!" was not appropriate. During my meal time, there was a French family around me. No problems there but when we usually have meals, they are supposed to put their chair in the upright position. These people did not do it and the steward did not tell them to raise their seat in the upright position. However, I was told to do so! So, me and another person next to me had to eat with the monitor almost touching our faces. Furthermore, a lady in front of me was putting her feet up and preventing another elder passenger from putting her seat back. To make it worse, she was continuously hitting her back into her seat, shaking my monitor while I was watching a movie. A crew member did speak to her about it but then she accused me of pushing her seat forward! The crew member gave me a death stare and told me to stop pushing the seat forward. I did not even touch her seat at all, if I did, she would know it. Her boyfriend also stood up and tried to push her seat even further past the maximum decline to no avail. None of these people were reprimanded but the steward, some bald guy, was extremely friendly with them and did not even try to instruct them to do anything until it was time to land. I resisted the urge to really argue with them because I would have obviously been seen as the aggressor (I have no idea why). I hardly said anything on this flight except "more wine please" and "sorry" if I bumped into someone accidentally. Overall, it was an annoying flight and I had to resist the urge to yell at the steward and the people he was overly friendly with. The happiest moment of this flight was leaving it.

The worst airline. Cancelled flight 30 min before boarding and rebooked on flight after 3 days.

The flight itself it was great nice food the crew were very nice and helpful, Checking in from Birmingham wasn't great long queues for bag dropped, And I had my hand luggage case taken away from me even though I requested to have it with me as I had breakables items. I was told I can not because of the length of the flight with no explanation at all no options was given for me to take my fragile items out of my case it was taken away with hold buggage I find the staff member who was checking me in very unpleasant !! Can we please be advise if the rules have changed about the the carry on hand luggage it will be easier to be advise on booking your tickect if we not allowed to take the hand luggage with me. Overall I had a good flight .

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

Great customer service. Frequent updates from the pilot. Smooth flight. Good entertainment. Meal service.

The flight got us safely from point a to point b and on time. For a transatlantic flight that isnt nothing. Flight crew was kind and professional. The seats are super uncomfortable (worse than domestic budget airlines) and the cabin was DIRTY.

Long unexplained delay, uncomfortable back row, long waits for trash collection.

Great service on the plane and by ground staff. great prices. I was able to change seats on the plane. The allocated seats cannot be changed when checkin in online. They have to be done at the airport if you check in at the airport or on the plane by asking a stewardess / steward.

Plane could have been cleaner. There were many crumbs and crud around the seat mounts.

I fly to the USA every 6wks on Ave and 99% of the time I fly Aer Lingus. If I fly BA I’m always disappointed. My only criticism is the food. I’m vegan and over the last year it’s got slightly better these last couple of flights but on the whole it’s not good! Salad and fruit salad for breakfast and that’s also the starter and desert for the lunch/dinner and the main is usually rice with fried veg 😳the pasta is pretty good though. That’s been the last 2 meals…. Everything else is fantastic.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

Flight staff very friendly and helpful where possible. Late flight and travelling with young child, cabin lights remained on for the duration of the flight which was a little disappointing considering the time of the flight. Overall very happy to travel with Aer Lingus.

Short flight so not much to rate. Surprised I had to pay for a soda.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

A bit disappointing. Our business class seats were not cleaned from previous flight. They were also missing headphones and bottled water. Dining options were not always available.

The flight from MAD to LIS was absolutely horrible since they didn't allow me to board the flight I had paid for. It turns out TAP has a rule hidden deep in their terms of services that if I miss any of the flights in my multi-city plan they will automatically cancel all the remaining flights. I don't know if this is unique to TAP or common practice, but it seems quite ridiculous that I pay for a flight plan and due to unforeseen circumstances miss one leg of that plan that all remaining plan flights be terminated.

The flight was delayed causing me to miss my connecting flight

they canceled the flight. I was at the airport a total of 8 hours. had to fly out the next day. No compensation so far.

They took 8 hours and eventually cancelled the flight. Compensation has been very lackluster and communication has been slow and terrible.

Flew Business with a forced upgrade. dint like how the bidding went . Then at the airport the seat was less than I paid. Not fair The flight crew was great, friendly and very kind. The plane felt like a bucket of bolts. The meal was the worst ever. Ive had better on tap . this was the most disappointing leg of our trip

The flight to Lisbon from Paris was quite pleasant. However, charging several Euros for each item of food left something to be desired. Further, there seemed to be no complimentary drinks, even water.

All of my clothes were completely soaked and wet when I got to my destination. The airline was careless and left my bag on the runway during a rain storm. Very disappointing! On the connecting flight in Lisbon we were made to wait on a bus crammmed in for 20min and standing. Unacceptable Very poor experience and most of my belongings ruined!

It was disappointing to have to pay for soft drinks/ water. The sandwich I wanted was not available. Servig happened to late in the flight.

Not good. Long lines for checkin. Cramped seats. Would only give one tiny cup of water. Had to use people movers. Won’t fly TAP again

It was fine. Communication was great as we were delayed

We arrived at the airport by taxi so as to be there two hours ahead of take-off. On arrival I received a message stating that the flight would be 85 minutes later than planned. An hour later another message stated that it would be a further 20 minutes late. There was no mention of the almost 2 hour delay once we boarded. Needless to say, they didn’t trumpet their “arrive-on-time” signal. At least we got there eventually.

Terrible experince. The flight was delayed for 4 hours and we had to sit in the plane for 30 minutes without AC. At least they shouod have given us complimentary bottles of water but no one had to buy them.

I haven't had a ok flight with Ryanair in so long!

Flight was delayed which happens but walking 15 mins to one gate to be then told it’s now changed to one 15 mins back then other way was frustrating

Long delay. Terrible airport - too busy, not enough seating or food/drink outlets.

The seat could have had more cushioning. My backside was sore after 30 minutes of the flight

Seats very uncomfortable for a 4 hour flight, what entertainment? Food overpriced. But sure it’s Ryan Air, what else would I expect?

The distance between seats was narrow. So my recommendation is to increase it

The flight departed and arrived on time. A member of the staff at the gate was awful. She asked me to get the duty free purchases out of the hand luggage to see if it would fit inside their box, which it did. It was the embarrassment in front of the other passengers and the hassle of getting my stuff out of the bag and back in again that was totally unnecessary. They try to squeeze every single euro they can get out of their passengers. The seats were uncomfortable with little space in between them. The flight was quite noisy with lots of announcements trying to sell food, drinks, gifts and souvenirs etc.

Usual friendly BA crew who were helpful and so kind to the kids. New business class cabin combined with 787 makes for a really enjoyable experience.

You were not able to check in online. Was not able to select a seat. The flight was delayed, so missed my connecting BA flight. Flight was rebooked, but to a different airport luckily for the same day. My friend that I was traveling with her flight was rebooted 24 hours later. Very disappointed.

Crew was great. Food definitely top 10% for airline food. Seat was comfortable and legroom was good, BUT the seats were too close together and I was touching arms with the guy next to me the entire flight. Also, I had an aisle seat, and although my arm was pulled right up to my side, I was bumped by passengers and crew at least 6x. I'm looking into business class next time. One last note: the whole British-AA airlines partnership thing was confusing. In 2024 this should be seamless, and passengers shouldn't need this # for BA and that # for AA. There should be a single unified way of messaging from the airlines and checking things for the passengers.

we departed 5 hours late. Instead of 10pm it was after 2AM and the business lounge thew us out at 1AM and everyone was standing around the boarding gates. When we did board, the crew was nice, served dinner and then was not to be seen again until we landed. No breakfast (which is not great for diabetes)

All fairly good as usual. Tried business class for the first time and enjoyed the inclusive champagne and good food. No entertainment as a less than 4 hour flight.

Horrible check in process. The app was unusable and the website very confusing

Lost bag on an hour and a half flight with no connections - ridiculous!

My worst flying experience so far. This flight was delayed a total of 42 hours and diverted to New York before it was finally cancelled. It was delayed 4 and a half hours in London. As we were scanning our boarding passes at the gate they advised that the flight was being diverted to JFK since the delays caused us to missed the open hours for Charlotte international customs and immigration. We were assured multiple times by airport personnel, flight attendants, and the Pilot that we would land at JFK go through customs and immigration and then reboard the plane to fly to Charlotte in the same night. When we landed in New York the pilot advised us as we were retrieving our carry on luggage that we were delayed till 10am the next morning and to see guest services to get a room for the night. During this time I had to purchase a room for a family member in Charlotte which drove over 4 and a half hours to pick us up from Charlotte. This could have been avoided if American Airlines had been up front about the delay. Then after standing in line for over 2 and a half hours at guest services we were taken by taxi to a hotel 30 minutes out of the way. Luckily I looked for other flights that night and found one at 8 am to get on. The initial flight which we were scheduled to fly to charlotte in was delayed 12 more times and was finally cancelled 42 hours after it was supposed to land. I am unaware of what happened to the guest that were supposed to fly on the flight after we were placed on another flight but 42 hours in delays for a direct flight is absolutely ridiculous.

Liked that my American Airlines status seamlessly transferred to BA so luggage check was free. Flights were on time, boarding quick. Wish they didn’t assign connecting gate so late at Heathrow.

Great!!! The first flight was a little painful because the chair wasn’t reclining and my back was destroyed by the time I got in London. But the second flight was perfect!! Super comfortable, the food was amazing, the crew super polite and helpful. Overall, I had a good experience
