'There is nothing to do in an airport or an airplane.'
I get this, but I've also met some interesting people and sometimes found myself deep in honest conversation for hours at a time. I'm saying this as someone who is usually reserved to the point of being anti-social.
There is nothing to do in an airport or an airplane. It’s like solitary confinement. All you can do is eat, drink, maybe buy a shitty book from the local duty free shop, and wait out your sentence.
A terribly uncomfortable experience.
