"Coach" Is Code for "Clown Car Seating"

The New York Times states the obvious: you have less space in "economy" seating on an airplane than you do in this telephone booth.

However, the NYT explains the decreasing quality of cheap air travel in terms of class conflict and diminishing returns for airlines. With the price of gas going up, the overhead costs for airlines has (no pun intended) skyrocketed. Hence, amenities for the more frugal traveler have been cut: pillows, peanuts, meals, and that precious inch and a half of space that distinguishes between elbowing your neighbor and being in your neighbor's lap. By contrast, first class service has remained luxurious, with on the ground drink service, food options, massive pillows for all, and noise-cancelling headphones. Any thoughts, anyone? Will the decreasing quality of service for the majority of customers in coach class cause travelers to change their habits? Or will people just put up with it, go home, and complain on sites like flightsfromhell.com?
