I did not care for the entertainment options.

Flight was 2 hours late leaving which was uncomfortable as the seats in the waiting srea are too hard

Extremely comfortable flight. Business class seats were very comfy. The layout of the cabin is a bit funky but it works very well. I would definitely fly BA business class again.

Don’t like paying for 1 checked bag and for seat assignment prior to check in. If you don’t pay for a seat assignment you end up in a middle seat on the wing!

Seats were awful offering very little room. Really not healthy to be so crowded!

This was my first time flying with British Airways and I wish every airline was this smooth. I checked my larger suitcase for free and boarding was on time. The plane is spacious and the food they provide is very good. The staff was very friendly and attentive. This flight was also the smoothest I have ever experienced during take off and landing. Definitely looking forward to fly with British Airways again!

Sullen, unsmiling, impolite passport and security staff at BWI. Unacceptable.

Breakfast is horrible...still frozen and never defrosted in time available to eat. Happened twice in a row now.
