Congratulations on finding the low fare. would NOT wait to book for the day after Thanksgiving....many of the cheaper fares are already sold out for that weekend...it is the busiest air travel weekend of the year. I would book on an airline with a reasonable change policy (like SW) so if per chance the fares go down you can get a credit for the difference....but I would NOT expect to snag any significantly discounted fares for that weekend. Don't know when you are returning, but you might do better there finding cheaper rates, but almost all discounts are blacked out for Thanksgiving weekend.
