One of the worst experience given the middle seat even asked for the change no one honored,boarded at the end and overall one of the worst experience

It was good although our flight to the UK was cancelled and rescheduled for two days later. This was after we were already seated on the plane. We missed the first leg of our trip. BA did put us up at a hotel and paid for our meals but we lost our hotel costs in Glasgow.

The crew was very nice and pleasant. We were very reluctant to book our flight with British Airlines because we had bad experience with their flight attendants on the previous trips, they were rude and not helpful.

I am a 25+ years American Airlines member. British Airways is simply above and beyond in every customer satisfaction category.

The seat pads are past there sell by date now and are uncomfotable. Also, with screens in the back of the seat, the seats shouldnt be able to recline as this puts rhe screen in your face.

1. The website didn’t allow me to checkin from London as I have Bangladesh passport with US permanent resident card. This pushed me to sit with my wife in the middle of two aisle seats, terrible experience! 2. BA should allow within 24 hours to checkin with other passport holders to choose better seats. A 2nd verification of travel documents can be done at the desk about immigration status. 3. Food options were poor for vegetarian passengers, try to introduce healthy options avoiding carb-dense food ingredients.

Cabin crew lovely and accommodating and I'll always fly BA in the future

It was perfect. The service was exceptional. I would never want to cross the Atlantic in anyone else's sardine tins.

As I have said it sucked, the ticket counter to have to find and pay for another airline to get home. Now I understand this happened over the weekend but they should have someone there to talk to us instead of throwing the regular crew under the bus.

Everything excellent except for bag drop off. We started at the D area and that was so slow that it was eventually closed just as we were about to go to a station. We then went to F. We got one suitcase checked and then the screen showed that the station was no longer operable. There were long lines everywhere so we had to ask if we could butt in to the next station to finish. Again, this was the only incident, otherwise it was an excellent flying experience
