The seating has become ridiculous… like a contest to see how narrow and short they can be made- forcing anyone over 5’1 to pay more to not be twisting oneself into a pretzel. Really insane- would have thought BA was better than this. Frankly- it cancels out a lot of the positive aspects.

The seating has become ridiculous… like a contest to see how narrow and short they can be made- forcing anyone over 5’1 to pay more to not be twisting oneself into a pretzel. Really insane- would have thought BA was better than this. Frankly- it cancels out a lot of the positive aspects.

flight was delayed from BWI to London - missed my connecting flight & then connecting flight (also British Air) was delayed - food is awful, TV & movie selection is great

Super tight economy class. My knees were hitting the back of seat in front of me (I'm only 5'6"). My small backpack (sized according to their required dimensions) would not fit under the seat in front of me because there is a box (is that the life jacket?) in the way. Over all, extremely uncomfortable. I forgive the tasteless food, but the tight seating was torture

Didn’t fly with them as someone had cancelled my flight

Online check-in 24 hours in advance something seems not so easy to check in to pick seats and to print a boarding pass

I like the crew, very welcoming. Food can be better. The seat arms don’t go up so. I could use the empty seat next to mine to relax better. 3hrs delay 😠

Boarding was efficient and quick, crew was very attentive, seats were comfortable.

Everything was very good! I personally struggled with the heat in the cabin for the first 2 hours

Very caring crew on board. Didn’t have dinner as I was sleeping. Was seating in the emergency row so I had comfortable leg room

Had a nice little suite although I couldn’t close the door (but I didn’t ask anyone to help). 5K is a nice seat and very private (you look in on first class). Enjoyable flight and nice crew.
