So if one finds oneself in the situation of the OP, booked on a 2-4-1 in F that has been oversold and they start bumping people, what is reasonable to expect / ask for as a resolution?
The downgrade to Club and £500 (cash?) seems OK to me in the context above.
If it reasonable to ask them to move both passengers to another flight in F (and pay an accommodation costs accrued if it is the next day)?
I admit I have a vested interest as I have a LHR-IAD-LHR trip in F coming up, booked using a 2-4-1. Outbound is F5 A4 but inbound is F0 A0 and all seats show as selected on both EF and BA such that I can't change my seat. Can I be confident that with F0 A0 they are not selling more, or could that 15th someone already bought a ticket and not got a seat?
Would also be interesting as a data point to know if the OP / Companion were status-holders with BA?
