Overview
- James (Jimmy) Dempsey takes over as interim CEO effective immediately, with Barry Biffle staying on as an advisor through Dec. 31.
- Frontier did not explain the leadership shift, and both Biffle and the company declined to comment.
- Board chair Bill Franke praised Dempsey as "uniquely qualified" to guide the airline.
- Dempsey joined Frontier in 2014 as chief financial officer after senior roles at Ryanair and PricewaterhouseCoopers.
- Frontier reported a $190 million loss in the first nine months of 2025 and its shares are down nearly 19% this year as budget carriers face higher costs and shifting demand.
