Ours definitely booked into M (LHR-AUH-LHR).
Manage my booking offers to upgrade us with either cash or avois- there are WT+ seats available in both directions which we’d happily take, particularly for the return.
Has as anyone has any luck upgrading online? After payment authorisation it comes back saying can’t change online and to contact BA...
In case it makes a difference, I’ve got my QF frequent flyer number applied and my partner’s got their BAEC number, would that impact it somehow?
