For those who have had problems getting AA to refund: the reservationists do not have the authority to refund. Go online, scroll down to Contact us, and then to Compliments and Complaints. Fill out the form, explaining the situation and requesting a refund (or whatever it is you want). Our flights were for November 25 thru December 9. I explained that our unit would not be available for us, and I asked for either a full refund or a credit to be used at any time in 2018, with no change fees. I received notice today that my purchase price will be refunded in full.
