Just got back from 4 hours of flying today and I was tooting it up the entire time! I think it might be because I was thinking about this thread, but it was really bad today.

I've also decided that airport/airplane food doesn't help. I don't think those stupid nut mixes and/or the cheeseburger and fries with a Sam Adams from Chili's in the B concourse of ORD really helped.
