That is what AA is saying, and the most likely scenario. If it ends before, then can change it, if not, push it further down. In any case, what happened to you was every flyers worst nightmare (but this is a never before seen event, all countries closing borders....). I understand that airlines are doing what they can, and in some cases that is not good enough. Good luck trying to get your money back, I hope it works, or at least the insurance covers you.
