Fear and airplanes

Why do people rush to get onto long flights--even when the plane isn't full?

It's not so they can get their carryons stowed... I notice that even people with no carryons push to get on.

(then they push to get off, at the end).

Even though they paid for the flight, it's not the flying they paid for. It's the getting there. And getting there means anxiety for some people. I think getting on and getting settled and not missing the flight no matter what are all steps that people take to reduce their anxiety.

Just wondering if that might apply to what you sell...
