SEATTLE, June 27, 2014 /PRNewswire/ -- Horizon Air's aircraft technicians and fleet service agents have ratified a new six-year contract, the airline and the International Brotherhood of Teamsters (IBT) announced today. "We're pleased that our technicians recognized the benefits of this contract and voted to ratify," says Yvonne Daverin, Horizon Air vice president of maintenance and engineering. "This contract provides both our technicians and our company with a strong, stable foundation as we continue to work together to build an even stronger airline." About 94 percent of members participated, and 53 percent of those voted in favor of the agreement. The contract, ratified well ahead of the amendable date of Dec. 16, 2014, includes a ratification bonus, annual wage increases and contract language enhancements.
