Ailing US Airways has admitted it needs to cut more costs if it is to emerge from Chapter 11 bankruptcy next year.
The airline will close its Orlando call centre and lay off another 2,500 of its 35,000 employees over the coming months.
The airline added that it needs unions to agree to changes in working practices that will make the carrier more efficient.
A reorganization plan needs to be filed with the bankruptcy court by Christmas.
Since the September 11 attacks, US Airways has laid off a total of 16,500 employees.
