The major airlines are raising fares 10 dollars per round trip trying to recoup the increased price of jet fuel. On Friday the price of a barrel of crude topped 69 dollars.

American, United Airlines and Continental Airlines all raised fares Thursday night, following a fare increase by Delta Air Lines, said Tom Parsons, chief executive of Bestfares.com, an Arlington, Texas-based firm that monitors airline ticket prices. US Airways matched the increase Friday.
While broad, the higher price does not include many markets where discount airlines, such as Dallas-based Southwest Airlines or AirTran Airways of Orlando, Fla., compete. It covers most advanced-purchase tickets, but did not affect last-minute tickets, which are generally the most expensive. via Buffalo News
