Some airline costs are going down, but ticket prices are still going up. The biggest expense for any airline is fuel, and the price of jet fuel is down 18% since August. Still, airfares are up 3% this year according to the industry trade group Airlines for America. And they've climbed 31% since 2009. But the high prices haven't chased away fliers-planes are more packed than they've ever been. About 85% of seats have been filled so far this year, a record high.
