One to keep: A Boeing 757 at Pittsburgh International Airport

High fuel costs and a low-fares environment coupled with over-capacity in the airline industry has forced US Airways to take this step.

The return of aircraft will result in the firm cutting 14 flights across its network compared to February schedules.

It will also stop flying to two destinations.

However, the company said that even with the May changes, the number of available seat miles are expected to increase by between 4% and 6% year on year.
