Gates were changed at Heathrow with nothing show on the board about 200 plus people needed to take a tram to another section of the terminal. At JFK airport, we had to wait 1 hour(!) on the tarmac after a 7 hour flight to get a gate to deboard!!

Horrible experience. They broke the handle of my checked in suitcase and then refused pay for damages

I had a great experience on this flight! The crew was extremely helpful and attentive. Seats are very comfortable and the in flight entertainment was excellent.

The onboard service was fantastic, really in a class of its own

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

Our flight was delayed by over 6 hours. We then had to deplane, stay overnight in a hotel then fly out the next day, 23 hours late.

Never got on this AA flight since British Airways delayed my original flight 29 hours

A heated chicken pie as a snack was terrible and could not be eaten. It should never be served. The crew took a long time in cleaning up after meals

premium economy was comfortable. Service was nice and crew were pleasant. However, mid flight the bathroom was not clean. It would be nice if people learned to clean up after themselves.

It was one of our best flight experiences. The crew was fantastic, the service was top notch with a genuine smile on everyone’s face. Would highly recommend British Airways.
