Your argument is not with us, but rather with AA, who hasn't issued the waver. We can not do anything to force AA to issue a waiver, but we can give you advise on how to proceed and what to do for future travel. At this point the options are to postpone travel to future date in hopes that a change occurs thus allowing you to cancel trip for full refund free of charge. Bite the bullet pay the fee and move on. If option to bite the bullet, you might ask AA to see if they can reconsider the fee seeing that CX has issued waiver.
