As no headphones/ ear pieces in back of seat for entertainment system, would have been to been offered rather than asking & waiting a long time. I know we are in economy but cost of ticket was high.

Flight got delayed due to a technical issue, but they were quick to find an alternative airplane.

Seriously, not displaying departure gate until very last minute is awful. Specially when you have to take an elevator and then transport to go to the sub-terminal. That’s awful in such a busy airport as Heathrow. And I cannot choose seat on this flight because it’s run by British Airways, even entering locator code.

Somehow I got “offloaded” even though I had my boarding pass and was in transit Food is horrible Staff were nice and cheerful No headphones were provided on 11 hours flight

Same basket of unhealthy prepackaged snacks (junk food) which was depleted by the time it got to my row!!

The staff were very helpful with lots of refreshments on offer. The toilets were clean. The seats were comfortable and entertainment was good. No complaints, it was excellent.

The main flight was OK but the second flight was chaotic with delays

amazing! they were so kind and allowed us to sit on empty seats so we could stretch our legs and sleep good. Food is amazing as well plus dessert in the middle of the flight!

I had purchased a ticket that allowed one check bag yet I was still charged for my bag! the lady at the ticket counter was rude and condescending.

All the British airways staff were very helpful and friendly. Every thing was very smooth running from checking in boarding and arriving 40 minutes early. Which is a brilliant start to your holiday.

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 .

They cancelled our flight the morning of departure at 4:30am.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

The crew was very attentive and kept busy serving a variety of treats!

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.
