AA sent me paper vouchers as a refund for a booking. I used them to pay for a flight at a ticket counter, but the (pretty clueless) agent returned one to me, worth $170. I called CS and asked if they have any way of looking up to tell me if it's been spent, the agent said no and said further that if I've got it in hand, I can use it.
Does anyone know if this is accurate? Is there no tracking of these things in their system?
