The reason that airline travel is so unpleasant…
is because “To be GOVERNED is to be watched, inspected, spied upon, directed, law-driven, numbered, regulated, enrolled, indoctrinated, preached at, controlled, checked, estimated, valued, censured, commanded, by creatures who have neither the right nor the wisdom nor the virtue to do so. To be GOVERNED is to be at every operation, at every transaction noted, registered, counted, taxed, stamped, measured, numbered, assessed, licensed, authorized, admonished, prevented, forbidden, reformed, corrected, punished. It is, under pretext of public utility, and in the name of the general interest, to be place under contribution, drilled, fleeced, exploited, monopolized, extorted from, squeezed, hoaxed, robbed; then, at the slightest resistance, the first word of complaint, to be repressed, fined, vilified, harassed, hunted down, abused, clubbed, disarmed, bound, choked, imprisoned, judged, condemned, shot, deported, sacrificed, sold, betrayed; and to crown all, mocked, ridiculed, derided, outraged, dishonored. That is government; that is its justice; that is its morality.”
The elephant in the middle of the airport is: nobody likes flying because it’s so goddamned unpleasant to be poked, prodded, and shuffled around by government agents; to have to show up several hours in advance of your flight just to wait in interminable lines to be poked, prodded, and shuffled around; and then to sit and wait for hours on your flight to leave because you had to budget so much time in advance not to be lectured by the government agents about how to schedule your time or end up missing the flight because you didn’t allow enough of a cushion for unexpected delays.
There are market opportunities for airports and airlines to improve their service, sure, but the dominant fact about the air transport market is that it isn’t a free market. The most unpleasant aspects of flying are forcibly monopolized and forcibly implemented by the federal government (which has no reason to care whether you fly or not). Moreover, even many airline companies have little reason to make things more pleasant for their customers, because the market is cartelized and subsidized; they can reliably count on receiving billions in bailouts from the federal government if their bottom line ever falters.
The major players in the contact lens market all have strong reasons to scramble to do a better job at following what customers want on the margin. That doesn’t happen with most of the unpleasantness that flyers face.
(Similar remarks, of course, apply to why the government-cartelized rail industry remains mostly useless to the vast majority of people in the U.S.)
