The leadership team of the merged Delta and Northwest airlines under Delta chief executive Richard Anderson will include four Northwest executives and four Delta executives.

As previously announced, Anderson will continue as chief executive of the combined company, Delta said Tuesday. Ed Bastian, currently president and chief financial officer of Delta, will keep those positions and also serve as chief executive and president of Northwest Airlines. With the merger, NWA Inc. will temporarily become an operating subsidiary of Delta.

Northwest's chief executive, Doug Steenland, as previously announced will leave his position but will sit on the combined company's board of directors.

Northwest's senior vice president of human resources and labor relations, Mike Becker, will become executive vice president and chief operating officer of Northwest.

Mike Campbell, Steve Gorman and Glen Hauenstein from Delta will become executive vice presidents for the combined company. Campbell will serve as executive vice president of human resources, labor and communications. Gorman will be executive vice president of operations and Hauenstein will be executive vice president of revenue and network.

Ben Hirst, Laura Liu and Theresa Wise from Northwest will become senior vice presidents of the combined company. Hirst will be general counsel, while Liu will be senior vice president of international and Wise will be chief information officer.

The proposed merger is undergoing regulatory review. A meeting for a shareholder vote on the merger is scheduled for Sept. 25. The deal is expected to close by the end of the year pending approval by regulators and shareholders.
