Someone help me please.. I am trying to book AUS-SFO for 17th Jan night using my Avios. I can see the availability on AA but not on BA.. I called BA customer care, but even they can't see the availability for that particular flight, but AA is still showing it.. the tax difference is HUGE, otherwise I would have booked with AA..
Is there anyway to solve this issue and book it through BA Avios..???
