Usually I fly an evening flight ex-SEA on t-giving day to catch the VT/UVA football game that weekend <grin> but this year I'm flying the day before via-ORD. I'll see you outside the RCC if you want to come in as my guest :-D
Looks like you already took my one piece of advice for flying the day before a holiday: Get yourself in F! The Mr.Chicken and security lines will be much longer than usual. (In SEA for some reason 1P doesn't get to use the elite security line any more, just 1K and F.)
