Frontier Group Holdings Inc. (NASDAQ:ULCC) has named James G. Dempsey as its permanent president and chief executive officer, effective January 7, the airline said. Dempsey, who had been serving as interim CEO since December 2025, has also been appointed to the company’s board.
Dempsey has spent more than ten years with Frontier. Board chairman Bill Franke said his experience positions the airline to “capitalize on opportunities ahead” while continuing to protect its low-cost operating model.
Alongside the leadership update, the Denver-based carrier revised its outlook for the fourth quarter of 2025, saying it now expects adjusted diluted earnings per share to come in at the top end of its previously issued guidance range of $0.04 to $0.20. Frontier said stronger-than-expected revenue during the quarter more than offset the impact of a government shutdown.
The airline first issued its fourth-quarter guidance on November 5, 2025, and updated it again on December 15, 2025. Frontier operates the largest fleet of Airbus A320neo-family aircraft in the United States through its subsidiary, Frontier Airlines Inc.
