BA's IT stinks. It's something out of the 1960's. They can't reissue a ticket that's had changes without sending it to their ticketing department which takes several days to do something with it. In my case, they keep trying to charge the additional amount to an expired credit card rather than the updated one. I don't know of any other airline that can't reissue a ticket within a couple of minutes, if that. No other airline where if there's an amount due you can't go to their airport ticket counter and pay with a credit card (can't do this at LHR T-5). Does anyone in top management at BA care or even aware? They can't even issue a boarding pass with reasonably correct information. Flew BA267 last week in Club World. Departs at 3:40 p.m. Boarding pass stated boarding begins at 2:40 p.m. (a hour before !). Got to the gate at 2:30 p.m. and not a BA agent in sight. They eventually showed up at 3:00 p.m. and boarding started at 3:10. Why would a boarding pass state boarding begins an hour in advance when it doesn't and probably never has? It's just insane how this airline is run.
