Food options limited and quality wasn’t very good. I was I was in premium economy and the people in front of me pushed their seats back to fully reclined position which made it difficult for me. My seat wouldn’t recline at all. I suggest that BA restrict the recliner more. Also, the audio in my headset didn’t work unless I held it in all the time. Entertainment choices were good. Customer services is excellent. Thank you to BA team.

Horrible, the plane is just old and junky...Filthy restroom, seat was as hard as rock. The food, mystery side dish, inedible..geez..just Horrible. Never flying BA again

Club Europe is always lovely. I really enjoy everything about it. One thing that has changed in recent years though, is the swap to Prosecco from Champagne in the lounges. This is really disappointing. I really don’t like Prosecco, and always looked forward to a lovely glass of champagne in the lounge. Is it possible to change back? It does make the whole experience a little more of a luxury experience.

the service on Business class should be improved to be at par with industry leaders like Cathay Pacific and Singapore AIrlines. A lot of room for improvement.

The crew on the flight were not particularly pleasant and fluid restriction was an issue. I was not allowed to fill my water bottle. Crew didn't check on passengers other than meal service.

You will pay for everything and feels like the airplane is old

The luggage problem I previously mentioned was actually this flight

The flight was delayed due to snow in Frankfurt. There wasn't much information from BA or the airport, but Kayak was great and kept me informed of the delay and gate changes.

Late takeoff, but on time landing. Lost bags, 3 days to find them, still in transit to my location. Power outlets broken, Wi-Fi not working, so much for working on the long flight.

Good. For a long flight. The comfort of the seat could be better. Also, the food was « normal » plane food. Not indian plane food unfortunately! Everything else was smooth and great.
