Pinnacle Airlines Corp., which flies regional jets for Delta Air Lines, is still working its way through the bankruptcy process. A spokesman for the Memphis-based regional carrier tells the Pioneer Press the final report is several weeks. Pinnacle is exploring every opportunity to reduce costs, including whether to move its corporate headquarters to the Twin Cities.

The board of directors at Pinnacle Airlines has eliminated Detroit from consideration for its potential new headquarters, the Commercial Appeal reports. The Memphis-based regional carrier is considering whether to move its home office to save money. Minnesota is the only other option still in contention.

The cuts will be spread evenly across the company's Marshall and Bloomington offices. The company has about 2,500 Minnesota workers among its 16,000 employees. Two years ago its workforce was twenty percent larger.

Delta Airlines' primary headquarters and hub in Atlanta is flourishing. Not so at other hub cities. Since Delta absorbed Northwest Airlines, the Twin Cities area has lost 3,000 jobs associated with the carrier. In Memphis the number of flights has been nearly halved, pushing up air fares to the second highest in the nation. Behind Cincinnati. Which is also a Delta hub.

The Metropolitan Airports Commission has approached the Memphis-based company about moving its corporate headquarters to Minnesota -- bringing jobs, revenue and economic growth with it. Pinnacle bought Mesaba Airlines in July 2010 and closed that company's Eagan headquarters earlier this year. "We currently don't have plans to move but every opportunity to reduce costs will be considered," Pinnacle Airlines said in a statement emailed to the Star Tribune.

Delta Air Lines is relocating Edina-based MLT Vacations from Minnesota to its Atlanta headquarters over the next several months, the Atlanta Journal-Constitution. The company says roughly 160 employees in the Twin Cities will be offered the option to transfer. Delta is the dominant carrier in the Twin Cities after in acquired Northwest Airlines in 2008.
