I'm booked for BKK - LHR on 11/01 - not had a notification email yet, but like you I can see that it's not possible to buy any BA metal seat all the way through until the end of October 2022!
Question, so I'd be happy enough to be booked on Qatar, but do you think I'd be able to change the date too? Just I'm considering not going at all now, so if there was the option to move the dates to say April and with Qatar, then I'd like to do that, as I can't see any Avois availability on any airline between now and back end of next year (unsurprisingly).
Cheers
