US Airways President Scott Kirby and American Airlines’s Chief Restructuring Officer Bev Goulet will lead the integration of the two airlines, which is expected to be completed in the third quarter if their recently announced merger is approved by regulators.

As part of their new task, Kirby and Goulet will join a transition committee that “will be focused on our long-term goal of building a strong, profitable airline well equipped to invest in our people, products and technologies, so that we can keep our loyal customers and attract new ones,” the companies say in a letter to employees of both airlines.

The letter notes that Kirby led US Airways’ merger analysis and negotiations with AMR Corp. “During the due diligence process, he played a key role in shaping the revenue and cost benefits associated with a merger, as well as labor negotiations. Scott, along with many others on both teams, has worked hard to establish the collaborative relationship between both airlines’ labor unions. He has also worked closely with the American team over the last several weeks and has become well-versed in American’s operations,” the letter says.

Goulet, meanwhile, is recognized for her role in AMR’s current restructuring and help in negotiating the equity splits for the merger, which assigns 72% ownership of the “new American” to AMR creditors and 28% to US Airways shareholders.
