Late like always. Harassed over the new luggage policy even after paying for our bags. Online check constantly badgers you to buy bags, buy the perks, and book extra things like cars and hotels. Don’t bother unless you are traveling on a day trip. After luggage fees you pay more than Southwest with terrible service and always late.

Tried to check in online as per usual - what a nightmare. Couldn't change my seat, tried 16 times and was rejected from process at change seat screen every time. Ended up having to phone BA at 5.30 am in the UK on my mobile from the US as was automatically allocated last row non-aisle seat - the worst place on the plane. On hold with executive club for 25 mins - I'm dreading the charges. Executive club customer service also couldn't change the seat (no reason given) but could see a free seat was available and would put a note about seat change for the airport check in staff. Got to airport - told no note on system and that UK BA executive club customer service staff had 'lied' to me by check in staff at san diego End up sitting next to toilet with constant noise all night. I will not fly with BA again (other than to try and use up existing avios). Virgin are now giving way superior service on my transatlantic routes and swiss air for my short hauls. This flight was confirmation that ba no longer offers good value or service.
