I cancelled an AA flight booked using $300 Cap1 credit. I was issued a flight credit, however this flight credit cannot be used online on AA.com and can only be used by calling Cap1, which every time resulted in pricing tickets much higher than AA website. Is there any way to use this flight credit directly with AA? Like by calling AA or even by paying a reservation takeover fee to AA or any other way or trick that? Anybody has any experience resolving this?
