Flight was fine, food much better than anticipated, and flight attendants were helpful and friendly!

No entertainment and the seats are well worn.! To the point it feels like your sitting in a bowl

Excellent except for checking in at Madrid Airport. Waited in line for over an hour and a half. Not enough ticket agents available and they were moving those with earlier flight times up in order to get them through. People were not happy. Staff did their best to explain, but just not enough to meet the need.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

I am 70 with carry on bag. Was told to go down two flights of stairs the had to climb stairs at rear of plane. Skywalk to front of plane was not offered. I was in row 26

CVG to London was a good flight . Thank god the plane was not full . Seating was tighter than any international I’ve taken . We arrived in London 10 minutes early. Had it not been for handicap assistance I would have missed my connection. Had it not been for the extra 10 minutes because we landed early I would have missed my flight . 3 hours and 10 minutes from plane to plane as they were boarding when I arrived . None of that is the fault of British Air but the understaffed and confided security at LHR. Because of this I will never use British Air again unless I don’t land in London . Not the airlines fault but I never want to miss a flight because of the blunder in London . The worst I’ve ever encountered in international travel . Sorry British Air but your home needs better management.

Very disappointed late takeoff led them to rebook me on American and United. The latter was cancrllrfg

Flight was on time. The half sandwich offered doesn’t compare to the full meal offered by Egyptair. With BA there is no entertainment whilst on the Egyptair flight you get to choose form a range of movies and the flight map which I quite enjoy.

The flight from Porto was delayed by 3 hours. Arrived in the US late at night. Exhausted from all the waiting. And staff did not communicate well with customers.

If I have to decide again definitely I will pick another Airline…..British Airways NO MORE.
