I'm fairly new to AA. I need to buy a round-trip ticket, but I don't know my return date or even if I'm returning within the year, but I will eventually return. Is it possible to book the way over as a discount fare and the way back as refundable? My next question is, if I cancel the return portion of the ticket, how much will be refunded? The full value of the return ticket or some "residual" amount based on the price of a one-way? Thank you!
