Our flight was cancelled while we are on our way to the airport. So, no notice. We were rescheduled to another airline with a 2 hour later takeoff and so arrived at our destination on time. We pre-paid American Airlines $190 to upgrade our seats. No refund. So no use for AA or Kayak.

Our flight was cancelled while we are on our way to the airport. So, no notice. We were rescheduled to another airline with a 2 hour later takeoff and so arrived at our destination on time. We pre-paid American Airlines $190 to upgrade our seats. No refund. So no use for AA or Kayak.

Terrible, horrible, disappointing- without telling us they changed planes and moved and separated our seats to opposite sides - said they changed seats putting us together - got to airport to find no, they did not - we sat opposing sides of plane - food overly salty to inedible, never saw stewardess but once - it was terrible

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

This particular flight wasn't very full at the back, so there were three seats available for spreading out and getting relatively comfortable

Original flight delayed several times and finally canceled at 2:30 in the morning. Staff at the gate was not very helpful in resolving problems or communicating why there were delays. I spent 34 hours at the airport before I could leave, they couldn't book me on another early flight even after canceling my original flight. Next flight available after my original flight was canceled was 22 hours later. I will never fly American Airlines again.

It was good, the staff was friendly and it was a typical flight to Europe.

First leg of the flight was delayed by 2 1/2 hours with very little communication. We scrambled trying to talk to airline people at the airport about our connecting flight and received all different answers and no help. We ended up at our destination almost five hours when we were supposed to arrive. We ended up missing an afternoon that was already paid for due to the delays.

Flight left 2 hours late as it had to wait for luggage from American to be loaded. This cause me to miss my flight to Athens. The USB ports were broken so by the time I arrived in London my phone was out of battery.

Our 9:00 pm flight was cancelled on our way too the airport!!! No reason was given too us!!! So stressful!!! I couldn’t believe it!!! Thank goodness we arrived 6 hours ahead of time. We were able too get on an earlier flight. Than everything was great!!

Lady next to me was coughing profusely the entire flight, other lady moved seats because of it, 8 hours of that during an overnight flight is a bit much.

The seats are extra cramped if you are taller than 5’8! Spring for the extra legroom seats for sure if you have a long flight!

Very disappointed with British Airways. It has been over 24 hours and I still have not received my checked baggage or any proper update. Customer support has been unresponsive, making the situation even more frustrating. Poor baggage handling and lack of communication seriously impacted my travel experience.

Cancelled flight and re booked seats were a downgrade. British Airways said the upgrade was t available but when I checked it was but then they wouldn’t make it right

Overall ok. Best part has always been the sundae dessert.

Very good staff members with sincere passion and responsibility in their job.

Boarding was efficient and quick, crew was very attentive, seats were comfortable.

Had a nice little suite although I couldn’t close the door (but I didn’t ask anyone to help). 5K is a nice seat and very private (you look in on first class). Enjoyable flight and nice crew.

More Indian vegetarian food options would have been better Availability of seat selection free of charge 72 hours before departure would be great

A little better than outward journey but mild chaos at the boarding gate because some people with boarding cards from connecting flights had cards which weren't recognised
