Does anybody know if international buddy passes are refundable once the trip has commenced? I gave a buddy a pass to a friend for travel to Europe. Problem was that he had problems getting back and had to make other arrangements to get home. As such, he never used his return portion of his buddy pass.

Reading the refund policy is specifially says that "domestic" tickets may be refunded for 1 year or expiration of the pass. On international it says that something to the effect that the ticket can be reissued for up to a year, but says nothing about refunds.

What's the deal? Is my friend out of the return portion of his buddy pass?
