I'm looking at a flight that's F0 A0 J4 R4 D1. Would prefer to redeem BA OB points for first class travel (booking in A). But don't want to lose the chance of travel on this flight in business class (booking in D).

If I redeem into D, is there a fee to change to A? Would that be viewed as a cancellation and rebooking, even if passenger name and route and date are the same? http://www.britishairways.com/travel...s/public/en_gb is not clear at all.
