I purchased premier economy seats but I was seated one row off and was sitting in economy my bottle of water and cookie did not compare to the menus handed OP it in premier.

The flight was ok. The seats are so small. The free wifi for members was not an option on this flight. The one flight attendant, older woman with straight white/grey hair, was very rude. The gentleman next to me asked about the wifi since he was a member as well. He stated, accurately, that the option to enter the idea number was not available. Her response was, "I don't know what to tell you" and walked away from him. The rest of the staff was wonderful. I asked another flight attendant about the wifi, she said the free wifi was not enabled on that flight (true or not- at least she was friendly). It was also pretty dirty. When I opened the tray table it had mushed crumbs and there was a dirty used pair of ear buds in my seat pocket. Lastly the air vent above my head was working but stuck so I was unable to move it to face me when it got warm. I fly American often but this really was not a great flight.

Cramped seating but standard in all smaller aircrafts today no matter what airlines. Crew very helpful, friendly & attentive so makes up for that.

I like everything about British Airways. Excellence. Perfect. Exquisite service.

Ohooo it's fantastic 👏 I love it 😀 😍 ❤️ it's on time ⏲️

First time on BA but will fly with them from now on! Everything about the flight was superb!!!

Just fine. Could have done with a bigger snack - was just too mean to pay for one!

Changed the gate at the last minute but still very organised and lots of communication.

Was diverted to Aberdeen, then had to take a three hour bus ride to Glasgow. No one met us when we arrived here and I never received a hotel.

A nice quick and easy flight. Crew was friendly and it was comfortable.
