USAir said it will furlough more than 3,500 employees in a major restructuring brought on by higher fuel costs and the recession's negative affect on air travel.

"USAir is being restructured to survive and to be in position to rebuild for the future," Seth Schofield, the airline's president and chief operating officer, said Monday.The reorganization, which will be spread over the next few months, will involve closing four of the airline's 12 flight crew bases, a maintenance facility and a reservation office, USAir said.

The airline said the restructuring would result in the "furlough" of 3,585 employees, including about 660 pilots, 540 flight attendants, 505 maintenance and utility workers, 1,300 customer service agents, 305 reservations agents, and 275 staff members and managers.
