US Airways has announced that it has reached a tentative agreement on a new, four-year collective bargaining agreement with the Transport Workers Union (TWU) that represents the airline’s 164 flight dispatchers.

Once ratified by the members of the TWU, the contract will be the second agreement between the airline and flight dispatchers since the merger of US Airways and America West Airlines in 2005.

“We are very pleased to have reached a tentative agreement with the TWU and thank the union leadership for their dedication and continued partnership with the airline,” said US Airways’ Vice President Labor Relations Al Hemenway.

“This tentative agreement is a win-win for our employees and US Airways as it recognizes the contributions of our professional dispatchers while ensuring US Airways is well positioned for long-term success in a competitive environment.”

The TWU will be presenting the details of the tentative agreement to its members for consideration with an endorsement for ratification, which is expected to take place in the coming weeks. Once ratified, the new agreement will extend through June 2015.
