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.

One of the flight was cancelled. My experience was poor.

THe flight, crew and service was good. The only problem was the long delay and that the Captain's announcment about the delay was only in English on a BUDapest Hungary flight.: And no one spoke Hungarian from the flight crew.

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