I have a return ticket to NRT on AA. It's booked in Y and I've upgraded the outbound to J using point/miles. Unfortunately the return upgrade is not available, and I'm sitting on the waitlist. I really don't want to take the long flight back in Y so I'm prepared to simply use points for an award booking for a one way flight back from NRT, and as it happens the same return flight has availability for an award in F.

My question is, without canceling the return sector of the initial (paid) ticket, what would happen if I redeemed miles for an award in F on the exact same flight coming back? Will my two reservations be cancelled (one in Y one in F)? Or will something else bad happen? I am willing to phone up AA and cancel the return (paid) flight, but only once I'm in Japan, otherwise presumably they'd want to charge me the one way fare? But I'd be booking the return award separately before I leave for Japan.

Thanks for any advice you can give me!
