Scott, thanks for the info. It's great to know these kinds of things are on your radar screen
As for the food comment... I think unless you are guaranteed to be in First, the way things are today you should always plan on hitting McD's, PizzaHut, Joe's popcorn stand - or whatever floats your boat - on your way to the gate. I was so far down that stand-by list from DFW that I didn't think to run and get a carry-out, but was "fortunate" enough to get a bag of chips and a candy bar from the AA cart for just $6(!). Dinner of champions.
PS - I wasn't offered any free peanuts either!
