Furloughing a bunch of air traffic controllers has a pretty easy-to-predict effect on air travel: It causes delays.

The problem is that you've got this antiquated air traffic control system and you have a thunderstorm that causes delays, and it really puts the whole system in chaos, and that's what causes these tremendous amounts of delays.

A world with a sudden limit on air travel would be tremendously different from the one we live in now.

Because it's cheaper and easier to fly than ever before, air travel is becoming democratized.

Technology doesn't address everything - for example, air travel still sucks.

There are few places you can find silence. Air travel could be the last fortress of solitude.
