First time AA flyer here and would appreciate some advice. I'm flying LHR - LAX -OGG on two separate itineraries, the first leg with BA (redeemed with BA companion voucher) and the second leg with AA (AA redemption with CX miles). The BA leg covers baggage while AA doesn't. Just called the AA helpline and was told I will not be able to prepay the AA baggage fees and only option I have is to pick up my luggage at LAX and check-in again 'normally' and pay the fee at the AA check-in counter. Do I have any other option? She was able to link up my itineraries but it really defeats the purpose if my bags are not checked through to my final destination. Any of your expert advice would be greatly appreciated!
