Alaska Airlines’ fleet of Boeing aircraft is growing again. Seattle’s hometown airline is purchasing six more Boeing 737-900 Extended Range aircraft, valued at US$594 million, Boeing’s current list price. Four aircraft are scheduled for delivery in 2016 and two in 2017, bringing Alaska’s total of locally manufactured jets on order to 79.

“We’re delighted Boeing is able to expedite delivery of four of these new 737-900ERs, increasing the number of aircraft we’ll receive next year to 19,” said Andrew Harrison, Alaska Airlines executive vice president and chief revenue officer. “These comfortable and highly efficient jets will expand and strengthen our already leading Pacific Northwest network.”

“Alaska’s confidence in the 737-900ER is something that everyone at Boeing takes great pride in,” said Boeing Commercial Airplanes president and CEO Ray Conner. “As hometown partners, Alaska and Boeing have a shared vision to put the most innovative and fuel-efficient airplanes in the skies. The 737-900ER is a testament to that vision.”
