US-based Alaska Airlines has exercised the option to procure 52 Boeing 737 MAX aircraft and increase its fleet from 94 to 146.

The American airline company has also secured rights for 105 more aeroplanes through 2030, ensuring sufficient aircraft for fleet replacement and growth.

Alaska Airlines CEO Ben Minicucci said: “This investment secures aircraft to optimise our growth through the next decade, which we know will be a formidable competitive advantage.

“We’re proud of the strong financial foundation that uniquely positions Alaska to make this commitment to our future and of the fantastic partnership we share with our hometown aircraft manufacturer at Boeing.”

This order is said to be the largest in the company’s history.

The new 737 MAX will join Alaska Airline’s fleet, which includes 737-900ERs, 737-900s, 737-800s and 737-700s.

The airline will receive a new 737 MAX aircraft every ten days in 2023.

By the end of the decade, it is expected to operate more than 250 new aircraft from the 737 MAX series.

Alaska Airlines is on track to sunset Airbus aircraft by the end of next year.

Boeing Commercial Airplanes president and CEO Stan Deal said: “As Alaska Airlines sustainably grows its fleet, the 737 MAX family offers environmental performance and flexibility to expand service across its route network.

“Built in our Renton factory near Alaska’s headquarters in Washington state, these aeroplanes will carry passengers to destinations for years to come.”
