Ravn Alaska has a new boss: Southern California businessman Tom Hsieh is taking over the regional airline, replacing current CEO Rob McKinney. Hsieh is president of FLOAT Alaska LLC, the parent company of Ravn Alaska and New Pacific Airlines.

McKinney did not respond to several requests for comment.

Tina Hanley, Ravn's chief commercial officer, said there was no official statement from the company but confirmed that the airline was passing the baton to Hsieh.

Alaska Airlines has suspended its mileage-sharing agreement with Ravn in light of this news. Alaska Airlines Public Affairs Manager Tim Thompson said in an email to KUCB that the decision was the result of the recent “leadership change” at Ravn.

The restructuring at Ravn comes about four months after the company laid off more than a quarter of its 400-plus employees. The airline provided few details about the layoffs.

Many Unalaska residents have recently expressed concern about the reliability of local air service, citing frequent and unexplained outages on the airline that serves nine communities across Alaska, including Homer, St. Paul, Valdez and St. Mary's on the lower Yukon River.

According to Alaska's statement, travelers will no longer be able to purchase and redeem Ravn flights or earn miles on the website. Thompson said trips already booked will be honored. Travelers who purchased flights on Alaska's website before July 1 can still earn miles as long as they provide a mileage plan number.
