Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.

Very Stress free Lounges were superb. Crews were caring. I loved it.

The FA told me that the dinner was vegetable curry which turned out to be vegetarian (tofu) which I don’t care for but that was the only disappointing part of my trip.

Entertainment catalog certainly needs an upgrade to include better and latest content. Food was not good at all - they need to cook something edible. Five starts to the crew and on tim performance of British airways though!!

Very cramped seats in economy, difficult to get comfortable with your legs and feet and back. The seat width is ok but I’m average size. Food is HORRIBLE. Crew is friendly. Delays and very tight connections made it tough for navigating. We would have missed our connecting flight if it wasn’t delayed too. The terminal transit was slow and normally every 10 minutes before 8pm, after 8 pm is every 30 minutes!!!!! No free wine or drinks!! Below average attitude.

The flight was nearly empty so we were welcomed to spread out and relax. There was some turbulence but nothing too scary. The crew was lovely!! They engaged in conversation and were very friendly! The food is terrible!!! Horrible wooden utensils, they barely pierce the food or cut anything. I sat in basic economy and was very comfortable. Customer service at the desk was polite and helpful.

Leg room was better than expected. Lavatory’s were easy to access.crew was grea!

Horrible seat allocation. Boarding was slow. Food was average and so was entertainment. The TV terminal didn't work and so had to use remote.

Lost one checked bag.and wasted 30min waiting and filing missing baggage report. Very unsatisfied.
