Frontier Airlines appointed Michael Delehant as Executive Vice President and Chief Operating Officer, effective November 30, 2026. Delehant joins from Wizz Air, where he ran operational and commercial activities as group Managing Director. He previously held positions at Vueling and Southwest.

The appointment coincides with two senior departures. Trevor Stedke, Senior Vice President of Operations, and Alex Clerc, Senior Vice President of Customers, both exit on November 13. Frontier provided no stated reason for either departure.

James Fenner, Vice President of Revenue and Loyalty, becomes Senior Vice President and Chief Revenue Officer, overseeing pricing, revenue management, loyalty and network planning. Bobby Schroeter assumes the role of Chief Marketing Officer, covering brand and customer experience.

The leadership shuffle follows a difficult Q3 2026, when Frontier posted a $104 million loss compared with a $77 million loss the prior year. Revenue reached a record $1.36 billion, though the airline recorded a $40 million gain after removing special items.

CEO Jimmy Dempsey, in the role for approximately 10 months after Barry Biffle's departure in December, is reshaping the carrier's leadership. Delehant's background at two European low-cost carriers signals Frontier's strategic direction. Wizz Air operates independently without a network carrier model, while Vueling operates under International Airlines Group. Frontier has introduced a first-class product this year, a shift also adopted by Allegiant/Sun Country and JetBlue as carriers compete in the ultra-low-cost space.
