Pardon my ignorangce but I need some help with this, because I'm obviously missing something
I am flying AMS to LHR BA0433 on October 7.
The seating plan in MMB says the aircraft is an A320 - the seating plan is also corrupted (see pic below).
As a Gold member I have assigned seats 1A for my wife and 1B for me however all the plans of CE on the A320 say 1B does not exist.
I spoke to BA reservations and they say 1B is correct - how is this so?
