US Airways is hiking fees on overweight and oversized baggage sizes, a spokesperson for the airline said Wednesday.

For overweight bags that weight between 50 and 70 lbs., the price will increase from $50 to $90. For supersized bags that weigh in excess of 70 lbs., customers will have to pay $175. up from the previous price of $100.

Those fees are in addition to the base price for checked bags, which the airline is keeping the same at $25 for the first bag, and $35 for the second.

The new prices will apply to flights purchased on or after Feb. 1st for travel on or after March 1, 2011.

And there is more bad news for customers who travel with more than two bags. The prices for checking bags numbered 3 to 9 is increasing from $100 to $125.

In recent years, airlines have been increasing a la carte fees for things like changing flights, more legroom and checking bags in an effort to cope with rising fuel prices and falling revenue.
