Cancelled flight minutes before boarding. Rescheduled flight was two days later

The flight attendants were EXTREMELY personable and appreciated the service, lights going off after dinner (probably the norm, but I haven’t flown evening overnight flights in a while). Thank you!

Business class seats were very dated on my plane. Very little storage, charging ports were not easily accessible, tv screen kept flopping away. Vegetarian food was disappointing: hardly any protein and severely under-seasoned. Crew was lovely.

The food was ok, but not great. They delayed boarding in Portland and did not enforce group boarding. But the crew was excellent, went above and beyond.

The food was pathetic. There wasn't much leg room and recline space for such a long flight. No tea/ coffee for a 2-3 hour connecting flight without purchasing! Really!?

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
