Seattle-based Alaska Airlines announced Thursday its biggest aircraft order, the purchase of 50 Boeing jets.
The planes, three versions of the Boeing 737 jets, add to the current fleet of 120 Boeing 737s. But the airline said two-thirds of the new planes will replace aging aircraft.
"This order positions us for growth and ensures that we'll continue to operate the quietest and most fuel-efficient aircraft available for the foreseeable future," Alaska Airlines President and Chief Executive Brad Tilden said in a statement.
The price tag for the 50 Boeing jets would normally be $5 billion, but experts say Alaska Airlines is certain to get a discount for buying in bulk. The planes will be delivered between 2015 and 2022.
