• Call up BA later in the day once the UK call centre is open to have the two return tickets 'moved' to the 2-4-1 booking. This results in a partial Avios refund and a recalculation of the taxes payable (since there is now a return booking, rather than two one-way bookings).

Does anyone have any experience of having made this work?

Thanks in advance
