US Airways Fares Up
US Airways confirmed Thursday it has increased round trip fares by $4 to $10.
Price raises started as an attempt to increase revenue during slow travel months.
Southwest and Jetblue have also been considering raising airfare, but have not acted on it yet. American Airlines said it was considering matching US Airways' fare increase.
Airlines have attempted almost 20 fare hikes this year, but only half of those have been successful.
