I have about $75 in Ticketless Travel Funds I plan to use for a trip in October. These funds expire in January '06. If I book tickets for the October trip then the prices goes down and I rebook, earning new travel funds, when will these new funds expire? I believe I have read that these new funds would also expire in January, but it seems to me that any credit you have should be used first and then new payments applied, making the new credit good for a year from when I book the October trip. How would it work? Thanks!
