US Airways has announced plans to hire 500 pilots and flight attendants next year, in order to fill anticipated job openings due to attrition and retirement.

The company announced today that the 500 would come from the ranks of employees currently on furlough, as well as new hires. The majority of the returning and new employees will be on the job by July.

“Our crew member hiring needs are being driven primarily by planned retirements and attrition, as well as international growth,” said US Airways President Scott Kirby. “Today’s announcement is consistent with our previously announced plan to keep our domestic capacity flat in 2011, while growing international capacity by 8 percent.”

The carrier plans to fill 420 flight attendant positions and 80 pilot positions in 2011. US Airways will first offer the positions to employees currently on furlough. Once that process is completed, the airline will begin hiring new employees.

After the recall, US Airways said it will have no flight attendants on furlough, and may have up to 100 pilots remaining on furlough. When the recall and new hire process is complete, the airline said it will have approximately 4,970 active pilots and 7,300 active flight attendants.
