I asked for a window seat and when I got on the plane 24A did not have a window so was very not happy, but good and entertainment was good and the staff was very good, so the only complaint was the seating.

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.

My seat was in a good row. In our section it was the first row. But it was difficult tooperate seat entertainment features > table, screen, even though I often fly.

Better and more attentive crew and more food options. Leg space is very tight.

We left our sons tablet on the British Airways plane And we can’t get a hold of anyone to try to locate it. I have to call multiple numbers.

Sitting in the plane for an extended period of time was very hot and uncomfortable. Very late arrival happened to not affect me but many others probably missed their connection because it also took a long time to get to the terminal.

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.

The boarding to Gatwick was a breeze but the boarding from Gatwick was a nightmare. The onboard service to Gatwick had a lot to be desired but the onboard sevice from Gatwick was amazing ! Very nice,friendly and funny ! Would I recommend BA to anyone.? ! Yes I would!

Really quick check in and security at Heathrow Terminal 5. Staff on board were lovely and very friendly. Could have provided a few more drinks on the flight but they were available at the back of the plane.

Flight boarded and took off late for unknown reasons. Crew insisted we check our hand luggage due to full flight, which it was not even close to full. Then had to wait almost an hour a and a half for the hand luggage to come onto the luggage belt since it was loaded last. This came after many hours of traveling pregnant with my 6 year old daughter. Really didn’t appreciate the unnecessary delays. What the hell?
