United Airlines Chief Executive Officer Oscar Munoz shook up his management team, filling a chief financial officer position that had been vacant for a year and replacing a longtime chief revenue officer.

Andrew Levy was appointed as CFO, joining the third-largest U.S. airline from Allegiant Travel Co., United said in a statement Thursday. The role had been unfilled since last August, when John Rainey resigned to take the same position at Paypal Inc. Senior Vice President Gerald Laderman served on an interim basis.

The airline also appointed Julia Haywood as chief commercial officer, filling the role of Chief Revenue Officer James Compton, who is retiring at the end of the year. Haywood formerly was partner and managing director at The Boston Consulting Group.

The executive changes come just days after United reached agreements with its flight attendants and mechanics. The carrier’s approximately 25,000 attendants on Friday approved a contract that will unite United and Continental groups that had been prevented from working together since the two airlines merged in October 2010. The carrier and its mechanics union also reached agreement in principle on a contract that awaits approval by the Teamsters-represented membership.

Investors expect more changes. Munoz said in June that he was reviewing United’s operations, including whether its hubs and its route network were fulfilling their mission. He is trying to find $3.1 billion in extra revenue and savings to match the airline’s U.S. peers in profitability.
