Frontier Airlines Taps James Dempsey in Leadership Shakeup
Frontier Group Holdings, the parent company of Frontier Airlines, has announced President James G. Dempsey has been appointed interim CEO effective 15 December.
Now former CEO Barry L. Biffle will remain in an advisory capacity until the end of 2025.
Bill Franke, Board Chair, says: “Jimmy [James] has been an invaluable member of Frontier’s senior leadership team for more than 10 years and has played an instrumental role in the company’s evolution and growth during that time.”
We believe Jimmy is uniquely qualified to guide our airline into the future.
He also thanked the outgoing CEO, saying: “The Board of Directors is deeply appreciative of Barry’s leadership and dedicated service to Frontier over the past 11 years. We thank him for his many contributions during his tenure.”
Vision for Frontier
Discussing his appointment, Jimmy said: “I am honoured and excited to lead Frontier Airlines and thank the Board for its trust to shape Frontier’s future with our 13,000 plus dedicated and hardworking team members.
“With 13 bases and a strong cost advantage, I believe Frontier is well-positioned to deliver unrivalled value to customers across the United States.”
He added: “I look forward to partnering with our team to write Frontier’s next chapter as we strive to create long-term value for all stakeholders.”
The appointment, which takes place immediately, signals the board’s desire for continuity while the company navigates a challenging operating environment.
Financial and operational expertise
Jimmy joined Frontier in 2014 as Chief Financial Officer (CFO) and served in that role for more than nine years before being named President in October 2023.
As CFO, he played a central role in shaping Frontier’s ultra-low-cost business model, managing capital structure and overseeing the airline’s public listing.
Before joining Frontier, according to his LinkedIn, Jimmy spent more than a decade at Ryanair, Europe’s largest low-cost carrier. He joined the Irish airline in 2003 as Head of Investor Relations, working closely with equity analysts and institutional investors.
In 2006, he was promoted to Group Treasurer, where he oversaw risk management across business, including aircraft financing for a fleet of more than 250 aircraft, fuel, interest rate, currently hedging, online credit card payments processing and physical fuel procurement.
Earlier in his career, Jimmy worked at PricewaterhouseCoopers (PwC) as a manager in the technology, information, communications and entertainment division.
Company faces mounting challenges
The leadership change comes as Frontier continues to struggle with profitability following the pandemic.
The airline reported a net loss of US$190bn in the first nine months of 2025, compared with net income a year earlier, as higher labour and operating costs weighed on results.
Like other ultra-low-cost carriers, Frontier has also been affected by shifting consumer preferences. Many travellers have gravitated toward international travel and higher-end seating options, while an oversupply of domestic flights has pressured fares.
Frontier’s shares are down nearly 19% this year, underperforming the broader airline sector.
Barry, who has more than three decades of airline industry experience, led several recent initiatives aimed at attracting customers willing to pay more for additional space and amenities.
As interim CEO, Jimmy now takes the helm at a critical juncture, with investors closely watching whether the airline company can stabilise earnings, maintain its cost advantage and adapt its ultra-low-cost model to a changing travel market.
