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!

Is it American Airlines or British Airways? This is so confusing. I got it from Portugal.

Appreciate free wine and entertainment plus good meals. Also leg room

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.

I like the food this time compared to my departure. I’m seated at the isle so it’s comfortable but I have to pay $124 for seat selection

Flight delayed an hour due to plane maintenance issues after getting in line to board. Issue was plane galley ovens which eliminated hot meals for overseas flight. Cold selections were limited due to availability. Drink and meal service (already an hour delayed) was very slow. Upon arrival in Nashville, had to sit at gate for about 15 minutes before disembarking with no explanation. Local police then boarded plane as we were disembarking so maybe that was the issue.

Boarding good. Seats uncomfortable when lie flat. Food was awful. Tasted stale and chicken was dry. No live tv or flight map. Had to pay for internet.

Poor technical details on this plane. 1) There was no WiFi on an 8 hour long-haul flight. So no work could be done. That's below the standard expected for airlines these days. 2) The power outlet at my seat was busted and not working. 3) The headphone jack was loose and I had to keep adjusting my headphones to get good reception, or when it slipped out. - The flight was delayed to due mechanics. Sometimes this can't be avoided, I understand, and it's a big inconvenience to arrive that much later when traveling across time zones (then arriving at 4am from the prior time zone). - Also unique to this flight, the northern lights were visible on the right side of the aircraft, but I only found out after we landed (b/c again no wifi). I understand there are considerations about people being out of their seats to look, but I feel extremely disappointed and resentful that I wasn't told so that I could have a chance to look at this probably once-in-a-lifetime cosmic event from a view in the sky. - Flight crew was otherwise friendly and helpful.

I would have preferred something lighter for the second meal. Maybe a small sandwich .
