Alaska Airlines has placed the largest aircraft order in its history, committing to 105 Boeing 737-10s with purchase rights for 35 more, alongside five Boeing 787 Dreamliners intended as the larger 787-10 variant.

Boeing and the Seattle-based carrier announced the agreement on Wednesday. The narrowbody commitment covers high-density routes and fleet renewal, replacing aging 737s, while the widebody aircraft will support long-haul expansion to Europe and Asia.

"This fleet investment builds on the strong foundation Alaska has created to support steady, scalable and sustained growth," said Ben Minicucci, CEO of Alaska Air Group. He framed the order as a building block of the airline's Alaska Accelerate strategic plan.

The deal lifts Alaska's total orderbook with Boeing to 245 aircraft, on top of the 94 737 MAX aircraft the carrier currently operates. Alaska flies the 737-8 and 737-9 today, and although the new order centers on the 737-10, the airline says it retains flexibility to shift between models within the MAX family as requirements change.

The five additional 787s push Alaska's future widebody fleet to 17 aircraft. Alaska expects the jets to anchor its international growth strategy, targeting service to at least 12 long-haul international destinations from Seattle by 2030.

The scale of the plan extends well beyond this single order. Alaska Air Group's combined fleet, which includes the Hawaiian Airlines operation absorbed after the carriers' merger, totals 413 aircraft today. With future deliveries, the company projects more than 475 aircraft by 2030 and more than 550 by 2035 — a roughly 33% expansion over a decade.

The airline says the mix of growth aircraft and replacements will keep its fleet among the youngest and most fuel-efficient in the industry, a claim that will be tested against Boeing's delivery execution in the years ahead.

Executives from Alaska and Boeing, together with representatives from the US Department of Transportation, gathered in Seattle to mark the announcement. The event also unveiled the first Boeing 787-9 painted in Alaska's new global livery, a design inspired by the Aurora Borealis with deep midnight blue and emerald green tones. The airline said the paintwork took artists nearly 1,000 hours across 13 days to complete from nose to tail.

The brand architecture remains split between the two carriers. Alaska's narrowbody aircraft flying across North America will continue to carry the Alaska Native on the tail, while Hawaiian Airlines will keep its Pualani tail design on Airbus A321neos, A330s and Boeing 717s serving Hawai'i and routes to and from the islands.

With firm orders, purchase rights and a fleet plan stretching to 2035, Alaska has now tied its growth trajectory squarely to Boeing's production ramp across both the 737 and 787 lines.
