He argued that removing regulation would help foster a new, efficient equilibrium of price, quantity, and quality of air service;


Really? We no longer have delays, we have "even pricing" (here's an example):

FWA TO LAX
American Airlines: $577
Northwest Airlines $577
Delta Air Lines: $587
Continental Airlines: $663

IND TO LAX
Northwest Airlines: $158
ATA: $168
American West Airlines: $217
American Airlines: $229
AirTran Airways: $259
Independence Air: $331
United Airlines: $368

[Edit: Error, we have 3 Class C's in Indiana, forgot South Bend]
Yep, 2 of the Class C Airports in Indiana serving the largest and second largest cities in the state. Dead even: $158 (Indy) to $577 (Fort Wayne).

And quantity and quality of service? You're joking, right?
The quality is self-explanatory as anyone who ever flew coach in 1969 and then had to fly coach in 2005 can attest. The quantity? Hmmmm.... Eastern, Pan Am, TWA, Western, etc. As I said, de-regulation really made things better wrt competition. Feh.
