Alaska Airlines flight attendants have ratified a new five-year contract.

Included in the new contract are quality of life enhancements and pay increases that rank Alaska’s 3,400 flight attendants among the highest paid in the industry at every pay step.

Under the Railway Labor Act, which governs collective bargaining agreements in the airline industry, contracts do not expire, they only become amendable. The previous agreement became amendable on May 1, 2012 and the new contract will become amendable again on Dec. 17, 2019.
