The New York Times' Micheline Maynard has an interesting article on what airlines are doing to keep costs down as fuel costs go up, up and away.

"They are power-washing jet engines more often to get rid of grime, carrying less water for the bathroom faucets and toilets, and replacing passenger seats with lighter models."

And interesting analysis:

"'Eight years ago, 15 percent of the price of an airplane ticket went to pay for jet fuel; now, it is 40 percent, according to the Air Transport Association, the industry’s trade group.

If prices stay where they are, the nation’s airlines will collectively spend $61.2 billion this year on jet fuel — more than five times what they spent in 2002, when travel fell sharply after the September 2001 terrorist attacks."
