What's the worst (or best) thing about air travel?

We’re flying this week. (I’ll tell you where we went when we get back.)

I’m ok with being on a plane. The combo of several anxiety inducing things should be hell for me, but they somehow converge into some sort of zen-like state of chill while we’re in the air.

Airports though. Airports are hell on Earth. TSA. Lost souls. Stress everywhere.

I loathe it.

What’s the worst part for you? Or the best?
