Opting Out of Air Travel

TNC, with his usual eloquence, explains one of the reasons why he's choosing not to fly these days:

Finally there is the fact that, as much as possible, I should avoid supporting airline travel in its current American iteration. As I said before I don't do this expecting any kind of policy change--but The God of Policy is not omnipotent. I expect an end to that sick feeling I get whenever I see passengers arbitrarily herded into full-body scans, or stranded on runways for hours, or yanked from their seats and stripped searched. There is still value in looking oneself in the mirror--whatever one might hope to see. Thoughtful resistance, in and of itself, is valuable.

That's so well put I would only add to it the monetary factor: air travel is certainly not as inexpensive or convenient as it used to be. Given these facts, who can fault anyone for choosing to drive, take the train, or forgo the trip altogether?
