AA just canceled my flight for mechanical reasons. I was planning a one-night, one-day trip, but now I am flying to a connecting airport tonight, then completing the rest of my trip tomorrow morning. I will be able to make my afternoon appointment at my final destination, so the trip in not ruined, just less pleasant. I'm not asking AA for a hotel voucher, (which I think normally I would receive) because I plan to stay with friends who live near the connecting airport. However, I booked a pre-paid nonrefundable hotel room at my destination, and now I will not be able to use it. Is there a process where AA could refund my hotel expenses? Is that an appropriate request? Who would I contact?
