Air fare is expected to increase. The deregulation of airlines in the 1980's led to lower fares but at the expense of a sustainable business model.
Gone are the $99 fares, except of course at the last moment as airlines attempt to fill every seat on the sardine cans called planes.
USA Today reports "Airlines raise fares aimed at business travelers".
Even the en vogue Conde Nast Traveler reports "The total cost of air travel will rise, even if air fares don’t."
