The airline confirmed a firm order for 105 Boeing 737 MAX 10 airplanes and five Boeing 787-10 Dreamliners on Wednesday, with options for an additional 35 737s in the future. This order is a strategic investment that underscores the company's long-term growth and significant work for IAM members at Boeing and across the aerospace supply chain.

"This historic investment by Alaska Airlines is tremendous news for IAM members who help build the planes and our District 142 members at Alaska / Hawaiian," said IAM Union International President Brian Bryant. "Large-scale aircraft orders like this mean stability and opportunity for working families from factory floors to airline hubs and the entire U.S. aerospace and airline industries."

The Alaska order, covering both narrowbody and widebody aircraft, will modernize the carrier's fleet and expand its domestic and international reach. Deliveries are expected to begin as early as 2027 and extend through the next decade, sustaining a steady pipeline of work for Boeing and contractors across the country.

Alaska Airlines' historic investment in more than 100 Boeing aircraft sends a powerful message in our industry," said IAM Union Air Transport Territory General Vice President Richie Johnsen. "As the largest airline and aerospace union, the IAM will continue to lead in ensuring our members share in this growth with dignity and respect. This order will create good-paying jobs, open doors for the next generation of aviation workers, and further confirms that the airline industry has a strong and bright future."

"The workers we represent build and maintain these advanced aircraft," IAM Union Western Territory General Vice President Robert "Bobby" Martinez. "This investment demonstrates confidence in American manufacturing and the professionalism of our members at Boeing and throughout the aerospace industry."

IAM members were instrumental in advocating for policies that strengthened the aviation sector in recent years, including federal support that preserved jobs during the pandemic and legislative efforts to bolster aerospace manufacturing in the United States.

"I am extremely proud of IAM District 142 members for their work during the Alaska/Hawaiian Airlines merger," said IAM District 142 President and Directing General Chair John Coveny. "This announcement signals that our industry is strong thanks to the work of our members at Alaska Airlines. IAM District 142 is growing fast and our members continue to help lead the way in the airline industry.

"We look forward to working with industry partners as this order moves forward and brings new jobs, innovation and economic growth to communities coast to coast."
