Disliked having to wait a little longer to disembark from the plan when we landed in London

Disliked having to wait a little longer to disembark from the plan when we landed in London

Food should be better quality. Video screens have poor resolution and the library of movies is poor. The other airlines are much better.

The trip was smooth but the crew were very abrupt, snatching things before finished and being quite snappy when asked questions.

My wife and I love to travel, so we fly a lot. We've already logged 381,075 miles and with practically every major airline. But this flight was very disappointing. It started off well, with no delays and a new plane. But when lunchtime approached, all that good impression was ruined. Instead of white tablecloths, we were offered small, dark placemats, which, as it turned out, were perfectly adequate for the food. All the food offered—and my wife and I only took fish, and the meat—was not just bad, it was downright disgusting and not heated enough. The same applies to the appetizers. This was the first time in many years of traveling that we've been offered such disgusting food.

Lost luggage stuck no clothes and no word after 2 days leaving on cruise no stuff or clothes

Don’t know they cancelled the flight day before I was to leave. They sent a email at 9:00 pm at night saying they cancelled. That is the smooth way to say we don’t want your business! I think they didn’t have enough people booking so they cancelled the flight! It’s all about the money anymore there is no honesty in business.

The flight was canceled 3 hours after original take off time

Pathetic check in experience at JFK. Everything is self check in. Not enough staff present to help with when the check in process or the kiosk gets stuck. Staff present not welcoming or pleasant at all. On the other hand the NY based flight crew was great. Courteous and friendly throughout the flight. Special meals leave a lot to be desired. Kids meals should be made available when kids are flying and same goes for special kids meals too.

Flight was full, and would have preferred an aisle seat, but due to getting a late ticket ,the seat I had was adequate. The flight crew were very help full and hard working. Food and drink were excellent for the 11hr flight. Overall I was pleased with flight, and would recommend British Airways again.

The chicken adobo was a little too spicy but good otherwise. My personal opinion. Movie selection could be improved, too many horror movies. Could add a few more chick flicks! The flight was bumpy at times. We arrived a little early too! Flight attendants friendly.

The seats needs to be comfortables, at least please add more padding to the seats.

My flight from Dublin was delayed two hours which ment that I missed my connecting flight to Phoenix. American Airlines provided a hotel room and rebooked my flight for 7:30 AM the next day. I didn't get to the room until 11 pm and I had to be at the airport the next day by 5 AM. The airlines did their best but the schedule was challenging for an 81 year old.

Fast and sensible boarding was absolutely amazing. But extortionate wifi and seats that barely moved, making me unable to sleep, didn't do a lot of favors.

I liked the front row seats. A lot of leg room. The check-in window needs to be longer

We were very satisfied and would fly with Aer Lingus again in the future.

My flights with Aer Lingus were very good and I will definitely fly with them. Again in future trips to Ireland and Scotland.

Too hot. Asked for an extra glass of water and was ignored. Asked to sit in empty seats that were open because it was so hot and crowded and was denied and the seats were empty the entire flight

Terrible leg room - I’m 5’3” and my knees were touching the seat in front of me. When the person sitting in front of me leaned back, there was about 15 inches of space between my head and the TV screen which made it awkward to view movies. Last year they had decent food, but this year the only tasty item on the trip was dessert.

The flight was delayed leaving Philadelphia due to “catering” and consequently arrived in Dublin some 75 minutes later than scheduled. Consequently this caused me to miss my connecting flight to Glasgow and I had to spend the night in Dublin.

The flight from Cincinnati to Philadelphia was satisfactory and uneventful.

Flying on the Boeing 787 from Seattle to London was everything that I expected. Every thing was great.

Seat pitch is not enough to eat comfortably. When seat in front is reclined, your screen comes closer to your face. Ryanair seats are actually more comfortable.

The leg from Portland to Heathrow was great for a business class ticket. The BA leg from Heathrow to Lisbon was terrible. Basically coach seating with an empty seat between you and next passenger. Absolutely no leg room. Should not have been charged for business class and it was a 3 hour flight.

The flat beds. Other than that, the place was not clean.

Moved me away from my family and refused to fix it.

I have always been pleased with their service. Would not change a thing

Seating and food was the worst we have experienced in 35 years of traveling for both personal and busines .

Economy seats felt more cramped than other flights we have taken.7 hr, painful sitting hours 6 and 7. Web site difficult to deal with. Originally put in for 1 special meal due to type 2. Meal was awful. Tried to change selection to standard for return flight, on app and website, unable to complete that action.

I was sleeping during dinner service, no one bothered to offer meal later, I remained hungry….until I got a morning sandwich!

Need to offer Better food from LAX to London Service from London to Delhi very delayed after take off.
