I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

Terrible. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets

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

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

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.

Not sure if the crew were experiencing something unknown to me,but the service of passing water was non-existent.In addition,please take consideration when providing yogurt as alternative for breakfast as some of us, could be lactose intolerant.. thanks

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.

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.
