Gonna be tough. I was in England when flights resumed on Concorde last week. British Airways and AF were putting out half price specials on Concorde to get people to fly. According to the news reports it is really oversold until March or April. So I don't think they will be offering many reward trips.
Good LUCK! I hope you get it though! I flew Concorde on BA about 6 years ago and it was totally awesome. You have to do it if feasible it was the experience of a lifetime.
