By Jim Donovan: US Airways has raised the fee to check heavy luggage on its domestic flights to an extra $90 each-way, it used to be $50. The fee will be charged for bags that weigh between 51 and 70 pounds.

The new fees apply to tickets bought after Feb. 1

That new higher fee is on top of the $25 to check a first bag and $35 for a second bag, which are not changing.

By the way US Airways also raised fees on bags between 71 and 100 pounds to $175 each.
