My first check in at my origin checked my visa for my international flight but it needed to be checked again. While this is understandable, I had to wait in line for 2 hours to get this second check. More agents are needed to process travel issues in Heathrow. There were times during the 2 hour wait that there was only one person servicing the long line (I don't know where the others went). There were many agents milling about but not working the desk so it seemed as if there were plenty of people at work that day. I attempted to use the automated kiosk but because I had a new visa (not one in my passport). Again, most of this was understandable travel delays but the queue processing time was just horrible.

Online check-in not available from Istanbul to Las Vegas. The check-in process at the airport was extremely and inefficient period. Took us over an hour to check in. Besides that, everything else about British Airways was good

My screen didn't work for the first 9.5 hours of the flight. The crew could not resolve. I don't watch much media so I had been really excited to relax and watch a BBC special but couldn't. Then I tried to use the online streaming on my devices - that never worked but I do have about 7 charges on my credit card that I now have to dispute with BA. Pretty annoying. Also, they ran out of meals and they served meals that had a serve by date of 1/26. But the staff were all very friendly and helpful when they could help.

Very bad check in service. They hardly spoke of any English - at least in a way to communicate. Downgraded from Business due to seat malfunction. Could not even allocate a seat in economy with an empty seat next to me. So called manager at check in was a total waste of time

My flight from Zurich to London was delayed 2hours and 45minutes. It was awful.

Not enough food for a 4 hour trip…Lack of entertainment and with no WIfi accessibility I didn’t figure it out how to access free WiFi

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.
