Horizon Air and the International Brotherhood of Teamsters reached a tentative agreement in late September on a five-year contract extension for the airline’s 280 mechanics, fleet service agents and other fleet support employees. According to Horizon parent company Alaska Air Group, the proposed deal calls for wage increases and several unnamed “quality-of -life enhancements.”

Teamsters leaders scheduled a vote for late last month. If approved, the agreement would take effect early this month and become amendable in December 2019. Horizon’s mechanics and fleet service employees ratified their current contract in December 2010. That deal carried an amendable date of Dec. 16, 2014.
