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.

The flight was half full and I presume that the next few days are even less busy not sure why they are still charging a premium to change a flight.

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

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

They should. Heck planes more often not when they are suppose to be leaving causing delays

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

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.

This was one of the best travel experiences we've ever had with Ryanair. The flight boarded on time in Dublin, departed on time, and arrived on time in Split, even though the flight was full. The aircraft was clean, and all members of the cabin crew were both friendly and efficient. Even our fellow passengers were well behaved! So top marks to all concerned!

Good, everything went straight forward and on time, I am satisfied

Due to long security check and no last call announcements from Gate staff, my family and 12 other passengers missed the flight.

Perfect timing, perfect departure, lovely crew on the ground and in the air.

Good flight. Take off a little late but make up the time

Everything’s went straight forward, no issues, good service and friendly crew

Left on time and arrived on time both ways, thank you

Ryanair is the worst airline in Europe and easily one of the worst in the planet

The flight was 45 mins delayed but the crew provided water and necessities like tissues

Flight crew were pleasant. I was switched out of the seat that I paid for and got placed to the back of the plane without being told. British airways should at least refund me the seat purchase for that flight.

Our seats were moved by ticketing agent at Chicago, so we thought we were getting an upgrade. Turns out we were put next to 4 children 2 of which cried or screamed for the entire 7.5 hour flight. It was a terrible experience for us.

The aircraft left 5 hours later than original dipartire time They let all passengers board and sit for 3 hours in a hot air plain with no A/C. Than they made all passengers leave the air plain due to some issues to the engine. Passengers received 1 glass of water the entire time . Than they boarded everyone again and took almost another hour before they took off. I bought these tickets for my 74 years old mother, Julianna Horvathne Kas and my nephew, Balázs Kelemen. Definitely going to request for a compensations!!

British Air ways was good - American Airlines not: waited at gate for “mechanical issues” and stood at gate.. plane delayed, … staff at desk rude, had to check my personal carry on item, toilet not working… “please use the working one sparingly- it will overflow in the cabin”

Food is just horrible, by your own. There is no leg room and I am 5' 2" and I was struggling by the end of the 7.5 hours flight. There is no good music selection, I was looking for more classical music to listen to.

I realize it almost has to happen, but giving up one carry-on is difficult. With the standard one in the overhead and one under the seat, I believe it could have worked. We chose British Airways because of its baggage allowance, but giving up on carry-on is a major negative in choosing BA in the future. Again, it is understandable. Everything else is top notch. Thank you.

The flight was excellent with very attentive and friendly staff. Food was delicious and amenities were nice. Only trouble was the 1 hour and 20 mins I had to wait for luggage. Guess there was an electrical problem at the gate.

Economy class has no legroom so if you have the money worth to upgrade! Food was absolutely horrible! The crew was super nice!!!!!

the crew was very friendly. The check in staff was a different story. I was flying club and when I arrived at the check in desk the two people behind the desk waved me to another person. They were too busy chatting. This person checked me in and said to walk to the gate immediately. At it was 1h12mins before the flight, I asked if I could use the lounge. No, he said. Straight to the gate. Obviously it was crowded, uncomfortable and irritating as the flight was delayed and a herd of people were standing in front of the gate, hoping to get in first

Flight canceled two hours beforehand, BA reticketed us so that we would have had to leave from Edinburgh instead of Glasgow, where we were already at the airport. We would have arrived in Boston too late to get home to Vermont. Instead with some pressure we were reticketed from Glasgow on Lufthansa, which avoided Heathrow, a great benefit after our horrible experience at Heathrow when we arrived in Britain three weeks earlier. (Kayak assebled an itierary that did not leave adeqate time for the connection at Heathrow, where thousands of people were trying tio get through inadequate and badly staffed security and staff did not know the slightest details about where and which lines we should get in.) The British Airways travel experience is not to be recommended these days.
