Alaska Air Group, the parent company of Alaska Airlines and Hawaiian Airlines, has expanded its board of directors with the addition of former T-Mobile CEO Mike Sievert.
Sievert joined T-Mobile in 2012 and served as CEO between 2020 and 2025. He presided over a period of “significant value creation” at the telecommunications company, Alaska officials said, with T-Mobile’s market value increasing from about $60 billion to about $260 billion during his tenure.
Sievert currently serves as vice chairman of T-Mobile’s board of directors.
“Mike is a proven leader who understands how to grow a business, strengthen customer relationships, and execute at a global scale,” Alaska Air Group Board Chair Patty Bedient said in a news release. “His experience leading a highly competitive, customer-focused company, combined with his strong connection to Seattle, will make him a valuable addition to our board.”
Prior to joining T-Mobile, Sievert held leadership positions at Microsoft, AT&T, IBM, and Procter & Gamble. He is also a licensed pilot and owns an amphibious seaplane.
“I’ve long admired Alaska’s focus on operational performance and doing the right thing for their guests,” Sievert said in a statement. “I’m looking forward to contributing to the airline’s continued growth and helping strengthen its position as a global airline.”
Sievert’s appointment likely signals that Alaska will continue to expand internationally. Earlier this spring, the carrier launched its first routes from Seattle to Europe, presenting a new challenge to longtime competitor Delta. Alaska is also rolling out new premium products, specifically its International Business Class suites on its Boeing 787-9 Dreamliners.
With Sievert’s appointment, Alaska Air Group’s board has 10 independent director seats. Directors serve one-year terms upon election at the company’s annual meeting of stockholders.
