Southwest Airlines said on Wednesday it has reached a tentative agreement with the Transport Workers Union Local 556, representing nearly 19,000 flight attendants.

The union would communicate details about the agreement and the voting timeline directly to its members, the company said.

In the past two years, unions across the aerospace, construction, airline and rail industries have put up fights for higher wages and more benefits in a tight labor market.

In August, the airline reached a tentative labor agreement with the union that represents about 17,120 transport workers who handle ramp, operations, provisioning and cargo.
