My flight BA1489 GLA-LHR 1545-1710 on Sunday 2nd June 2024 was cancelled at short notice - I received the cancellation email at 0419 on the day of the flight. Thankfully I was able to rebook onto an earlier GLA-LHR flight. Is anybody able to help me find out the reason for the cancellation, or is it too late - i.e. do these things need to be found out on the day?
