Service was very good. Because I use a cane, I was allowed to use Priority Boarding. Biggest problem was extremely limited leg room in Economy class seats. For airplane food, it was alright.

Service was very good. Because I use a cane, I was allowed to use Priority Boarding. Biggest problem was extremely limited leg room in Economy class seats. For airplane food, it was alright.

Was late but that airport/storm fault. Flight was full but comfortable. Food quite nice. Unfortunate that I had a rather miserable attendant, others were much friendlier

Experience was good. Could have been better if we didn’t have to board an hour before the flight to ghana and miss relaxing time in the lounge. That process was very stressful

I was charged fees for check in bags at the airport by British Airways. It was supposed to be no charge but Kayak messed up my booking apparently and I had to pay for check in bags. I paid $175.

Flight delay and can’t much help passenger do the change connecting flight.

The seats in airbus from LA to London are uncomfortable. They are too narrow. I am a slim person but felt cramped. The way the seats are laid out really hinders privacy. You are forced to look at the person next to you which is awkward, Also the entertainment on the same leg was limited. The crew was excellent and attentive and the food was decent. The seats on London to Delhi leg were way better. The crew again was very attentive and polite.

British Airways canceled my flight and I had to fly on Lufthansa the next day. What a garbage airline 🗑️

The whole experience was great. The only improvement would be the entertainment selection

It was good overall. Entertainment was ok, one of the TV screens had issue. Bit old plane but leg space was good. Overhead luggage had good space. The worst part was experience at Heathrow airport, it was total chaos.

Flight was delayed. Thankfully I wasn't in a rush. The airport experience (shops, amenities, ample restaurants, coffee shops, seats with charging) was very good) was very good as was the boarding which was orderly and organised. The flight was short so whilst there was no entertainment I thought that was ok especially in the age of smart phones and kindles. It would have been nice to have usbc charging supported at my seat but again it was a short flight so no drama. Overall a positive experience flying from London to Edinburgh with BA.
