I truly can't imagine an industry that would be more difficult to run a company in:
* Everything is highly regulated.
* The dominant expense is a highly-volatile commodity controlled mainly by unpredictable/hostile countries.
* Your product has been totally commoditized by airfare-pricing websites.
* People get angry at your company when the weather is bad.
* Use of your product is inextricably linked to the abhorrent process of airport security.
* There is the continual potential of a terrorist attack decimating your sales overnight.
Any decently smart airline is hoarding some profits, because if they don't they will go bankrupt the next time fuel costs spike or something scary happens during a U.S. flight.
