Both AA and QF are selling the same flight but I purchased it thru Qantas therefore it is coded as QF309. But I see it as AA72 when I log into my AA account. I called AA to apply the SWU and they told me they cannot take hold of the Qantas ticket, so I guess Qantas is indeed imposing the restriction. So, I am wondering, can I try to call the EXP number within 24 hrs of flight departure to apply the SWU? I know I will be pretty far down the waitlist but worth a try.
