24 hours ago around the time that check-in opened I upgraded my cabin online, paid the upgrade fee and then went back to manage my booking to check in. When I tried to check in or select a seat I kept receiving error messages so I called up and was told on several occasions that it was just an error with the website and if I waited it would resolve itself shortly.

As you might imagine the errors never resolved and I was not able to check in online or select a seat.

When I arrived at the airport at check-in I was told that I had been placed on a standby list for the upgraded cabin because there were no seats available and that I would only be offered a upgraded seat if someone did not show up. In the end there were no free seats and I had to go back to the lower cabin, in a seat which was newly assigned to me. In the end, I was in a worse position than before the “upgrade”. None of the call centre operators were able to tell me what was happening which was quite frustrating because if I had known I was on standby I would’ve cancelled the upgrade and retained my old seat.

Not entirely surprising given BA’s IT is from the 1950s but wondering if anyone else has had a similar experience and if so how BA dealt with it?
