Something you may want to consider....credits expire after 1 year. There are only a limited number of reward seats on any given flight. You may not able to get 3 reward seats on one flight. I believe you can get the voucher right before the credits expire and then have a year on the voucher, but that's just what I've heard and don't have firsthand knowledge. Rewards on Orlando flights in April are EXTREMELY hard to get. I would do the math and find a way to use the rewards on the Dec. flight as those seats will be made available first and are probably easier to get. You might be able to get 2 seats in Dec. and 1 in Apr. It's been my experience that the Dec. reward seats are gone before the Apr. flights are released. You sure don't want to end up eating your rewards vouchers! Be sure to check the blackout periods!! If you're travelling around the holidays not all dates will be offered and anywhere close is going to force you to be vigilant about schedule releases and be the first request in line. Hope this makes sense. Also keep in mind that if your first trip isn't scheduled until Jun of 2008 there's no guarantee that the gc program will still be in effect when you're ready to buy.
