Taking off and landing were smooth. I didn't have anything to complain about.

The sad case is that BA is often late. I missed my connection outbound and then was rebooked in another biz class seat some 10 hours later. I opted to change to economy (no compensation refunded of course) that was only 5 hours later. On the return journey, once again changing planes was very challenging. This time we landed only a little bit late, but deplaning took a long time so the connection was very much in doubt. Some serious running and sweat later, I managed to make the connection but my luggage did not. No messages about the missing luggage, so I had to wait until the entire bag return process was over before seeking out an agent. There was only one and well over 50 passengers waiting to speaking with her. She was quite pleasant, but it took 1 hour and 45 minutes from touchdown to leaving the airport.

First time flying with BA and I will do it again. Staff at airport and on board were very nice and helpful

BA charged me 70 euros for one bag on my return after having recognized my frequent flier status and charging me nothing for the same bag on the outbound. Their employees are not well trained and rules are inconsistently applied.

I couldn’t select my seat until I checked in at the airport. Extremely difficult to talk to a customer service representative. Also, the gate announcement doesn’t appear until less than an hour before boarding.

They over sold the flight and I was not able to board. Had to buy two tickets so I would not miss my connection.

Wonderful service and very comfy in the bulkhead in Economy Plus! Delicious food.

On the flight from Venice to London even it’s short, 2 hours 20 minutes and mostly people are on vacation, it’s ridiculous to change money for the cup of tea or coffee. Also it’s to much to charge 80$ for 1 piece of luggage

Flying economy is like being packed into a sardine can.

The BA team at Sky Harbor is deplorable, full of unnecessary attitude and poor communication. It seems like every member of the team was looking at another to solve the problem, instead of taking agency to do so themselves. I saw no less than 6 altercations with the same gate agent where he threatened to revoke the passengers boarding pass for asking a wildly reasonable question, something as simple as where the cue to board was. I’ve complained to BA before but it seems this isn’t an issue for them, which is very disappointing
