Look! Up in the sky! It's a bird, it's a plane, it's... higher prices yet again!

American Airlines raised its prices yet again this weekend, tacking on another $5 to its leisure travel fares. For those keeping score at home, this is the fifth price increase by the major airlines already this year.

Jamie Baker of J.P. Morgan

tells

the

Dallas Star-Telegram

that he sees "no evidence of passenger resistance to higher fares." Translation? The airlines likely aren't done yet.
