Under the new arrangement, designed to take effect in January, all Horizon flights will operate under whats known as a capacity purchase agreement with Alaska. Under that agreement, Horizon will fly the routes that Alaska dictates for a price fixed by its sister carrier. Alaska will market those flights and retain all of the ticket revenue.
The airline also announced recently that it is outsourcing heavy maintenance on its fleet to an Idaho firm and shuttering its Portland heavy maintenance operation. About 100 mechanics work there now. Some could be transferred to new line maintenance operations in other cities.
The airline also plans to combine its operations center, now in Portland, with Alaskas operations center near Seattle-Tacoma International Airport.
