Piedmont Airlines, a wholly owned subsidiary of US Airways, has reached a tentative agreement with the Communications Workers of America (CWA) on a four-and-a-half year collective bargaining agreement. CWA represents the airline’s more than 3,000 fleet and passenger service employees.

The CWA will present the details of the tentative agreement to its members with an endorsement for ratification, which is expected to take place in July. Once ratified, the agreement will extend through January 2017.
