Umm the airline unless you bought a transfer/refund ticket is NOT going to allow you to sell your ticket to someone else. I tried to transfer one, so my other sister could come cause my middle sister couldnt make it, and they said that ws NOT allowed unless I purchased a ticket of that type as they do not allow name changes once it's in your name. They stated it would be close to 2000 dollars for her to get a ticket I guess meaning buy a new ticket on a days notice. You will need to call the airline you bought the ticket through cause with stricter policies now they have made it hard unless you are willing to pay big bucks, or have already paid the extra amount for that sort of ticket.
