I'm traveling to Orlando from Chicago via Southwest with a party of twelve 12/16-12/21. I usually stand back and play the last minute deal game, but I'm concerned about the gamble because I've never flown at Christmas time. Would it be wise to purchase tickets soon or do you think they will sell out on the very few non-stop flights offered? It's killing me to have to pay the fares offered right now. Any inside scoop on traveling close to Christmas?
