Thanks. That's what I thought. Not sure I understand the logic though. Im my case, I originally made reservations in April for a flight in September. I've had to change it a couple times, and also changed it when the price dropped, so I have about $100 in credits. I just don't see why they should expire in April and not September. I think they shoiuld expire based on the original TRAVEL date not the original booking date. For instance, my credits should be good for travel through September 2010, 1 year from my original travel date.
