Service was very good. Because I use a cane, I was allowed to use Priority Boarding. Biggest problem was extremely limited leg room in Economy class seats. For airplane food, it was alright.

Service was very good. Because I use a cane, I was allowed to use Priority Boarding. Biggest problem was extremely limited leg room in Economy class seats. For airplane food, it was alright.

Terrible. A 6 hour delay and no one could be bothered to communicate or help change routes to avoid unnecessary delays and frustration

Was late but that airport/storm fault. Flight was full but comfortable. Food quite nice. Unfortunate that I had a rather miserable attendant, others were much friendlier

Changed flight terminals/gates twice. The staff and hospitality was good.

Boarding was efficient. Flight left on time. Wasn’t full so we could spread out a bit. Food was ok.

Used to be my "go to" airline but would be my last choice these days. I think some of the cabin crew believe it would be a great job if it wasn't for the customers.

I love travelling with British airways because everything is supper goog

Not that great. There were no entertainment screens, internet, or any way to track the flight path. The seats were fixed in order not to recline at all. The crew and the staff at the check-in counters were the only nice thing.

Experience was good. Could have been better if we didn’t have to board an hour before the flight to ghana and miss relaxing time in the lounge. That process was very stressful

my flight was canceled and rescheduled for two days later
