LOS ANGELES (CBS) — The nation’s largest low-cost airline is boosting its ticket prices once again.

Southwest, which flies to and from LAX, Bob Hope, Ontario and John Wayne airports, raised prices on most domestic flights by $10 Thursday.

The company says its being forced to increase prices to make up for operating costs and the high price of jet fuel.

Analysts say there are indications that other airlines will follow suit with more fare hikes.
