Reserving BA Biz Class Seat
New to the BA game. Booked an AA award tix from LAX-LHR-CDG for next year. the LHR-CDG leg is on BA. BA won't let me reserve my seat now for free (lowest cost to reserve now is $28). BA says i can pick it 24 hours before flight for free, but I worry if I'm not quick enough, all the biz class seats will be spoken for and I'm stuck. Any helpful hacks or am I gonna have to wait? Thanks!
