I'm American and knew what day it was. I didn't think it would do in a flight and would have been a nice one. OTOH, total crap day at DEN with only the Sun after Thanksgiving usually worse. My son is a Denver firefighter and I leave the country at Thanksgiving so he can work and/or pick up overtime with no guilt. London is often my choice because it's already in the Christmas swing of things I can overdose on concerts and theatre.
