Here's a tip for making your experience flying in an airplane more comfortable: just wear sweatpants for the trip.
This was something I never thought up myself, but I saw a co-worker on a business trip doing this, and I realized the genius of it. Who are you trying to impress when you are flying? The pilot? The stewardesses? Your fellow passengers? That attractive woman you saw during a layover who was going to a different destination?
Wearing something comfortable just makes things easier.
