SeaTac's Alaska Airlines has ordered five more Boeing 737-900ERs worth nearly half a billion dollars at list prices to augment its all-Boeing fleet.
The 737-900ER is the largest version of Boeing's popular 737 family of aircraft. Boeing has sold more than 10,000 of those planes, making the 737 the world's best-selling jetliner.
Alaska said it will use the 181-seat, single-aisle aircraft to add capacity to its fleet.
Two of the aircraft will arrive in 2015 followed by two more in 2016 and one in 2017. By the end of 2014, Alaska will have 134 Boeing 737s in its fleet. Those planes range in size from the 72-seat 737-400C, a plane that carries both passenger and cargo, to the 737-900ER with 181 seats.
Alaska has 31 additional Boeing 737s on order for delivery through 2017. The airline, unlike some of its larger rivals, is growing its capacity by four to eight percent a year. Some larger airlines are shrinking their capacity to eliminate unprofitable routes.
In recent months, Alaska has added new destinations from Seattle, Portland and San Diego.
All 737s are built in Boeing's Renton plant.
