Frontier Taps Insider James Dempsey as CEO as Ultra-Low-Cost Rivals Pull Back

Frontier Group Holdings has promoted James G. “Jimmy” Dempsey to chief executive officer, installing a longtime insider and former finance chief at the top of one of the country’s last large standalone ultra-low-cost carriers as the budget airline segment faces mounting strain.

The parent of Denver-based Frontier Airlines said its board on Jan. 7 elected Dempsey president and CEO and added him to the company’s board of directors. The move, announced publicly Jan. 8, ends a brief interim period that began Dec. 15 when he stepped in following the exit of veteran CEO Barry L. Biffle.

The company paired the leadership news with an update that it now expects fourth-quarter 2025 earnings to come in at the high end of its prior forecast, a signal aimed at investors after a year of losses and a steep slide in the share price.

“It’s an exciting time at Frontier as we kick off 2026,” Dempsey said in a statement. He credited the “dedication and hard work” of the airline’s more than 13,000 employees and said he would work with “Team Frontier and the board … to execute and deliver long-term shareholder value.”

Board bets on continuity, cost focus

Dempsey’s appointment signals continuity at Frontier, which brands itself as “America’s Low Fare Airline” and relies on ultra-low base fares paired with extensive add-on fees. The move also comes as rivals in the ultra-low-cost carrier (ULCC) segment shrink or consolidate amid soft domestic demand and higher costs.

Board Chair William A. “Bill” Franke, whose private equity firm Indigo Partners is a major shareholder, said Dempsey “has demonstrated over his more than a decade at Frontier that he’s the right leader to drive our airline forward.”

Franke said Dempsey’s experience would help Frontier “capitalize on the opportunities we see ahead, preserve our industry-leading cost advantage and guide Frontier into the future.”

According to a securities filing, Dempsey was also appointed a Class III director with a term running through the company’s 2027 annual shareholder meeting.

The announcement drew a modestly positive initial reaction. Frontier shares rose about 2.5% in premarket trading on Jan. 8 after the news and profit update, though the stock remains down roughly 40% or more over the past year.

Record revenue, then red ink

The leadership change follows a volatile stretch for the airline.

Frontier reported record revenue in 2024, including $1 billion in fourth-quarter revenue and $3.8 billion for the year, along with a modest profit in the final three months and nearly $1 billion in liquidity. But that momentum did not carry into 2025.

In the second and third quarters of 2025, Frontier posted net losses of roughly $70 million to $77 million each period as revenue slipped below expectations and pricing softened. The carrier cited weak domestic leisure demand and pressure on fares—trends that also led larger rivals, including Delta Air Lines and American Airlines, to trim outlooks.

Frontier’s liquidity declined over the year as it absorbed losses and continued fleet investment. At the end of the third quarter, it reported about $691 million in cash and available credit, though it later completed a note offering that added resources.

In November, management told investors it expected to return to profitability in the fourth quarter, guiding to adjusted diluted earnings per share of 4 cents to 20 cents. That outlook was reiterated when Dempsey was named interim CEO in December and tightened to the high end of the range in the Jan. 8 release, with the company citing stronger-than-expected revenue even as a federal government shutdown disrupted some travel.

Veteran of Frontier and Ryanair

Dempsey, 50, joined Frontier in 2014 as chief financial officer after more than a decade at European budget airline Ryanair Holdings. He served as Frontier’s CFO through 2023, overseeing the balance sheet and aircraft financing, before being promoted to president in October 2023 with responsibility for commercial strategy, customer care and operations planning.

Before moving to Frontier, Dempsey was Ryanair’s treasurer from 2006 to 2014 and previously led investor relations there. He began his career at PricewaterhouseCoopers. He holds a bachelor of commerce degree from University College Dublin and is a fellow of the Institute of Chartered Accountants in Ireland.

Under Dempsey and Biffle, Frontier has emphasized fleet modernization and high-density seating to keep per-seat costs low. The airline operates Airbus A320neo-family aircraft and has hundreds more on order. It has also rolled out a new “first-class” seating option on some routes and expanded loyalty and ancillary revenue streams to lift revenue per passenger while maintaining low fares.

Shrinking field of ultra-low-cost rivals

Dempsey takes the helm as the U.S. ULCC segment undergoes rapid change.

Spirit Airlines—one of Frontier’s closest competitors—has struggled through repeated trips to bankruptcy court. Spirit first sought protection in late 2024, then filed again in August 2025 after a failed restructuring attempt. As part of its efforts, Spirit has cut its fleet, furloughed workers and reduced capacity on dozens of routes.

Earlier in 2025, Spirit rejected a Frontier offer that would have combined the carriers, arguing it could remain viable as a standalone airline. Frontier had previously pursued a separate merger with Spirit that ultimately collapsed after legal and regulatory scrutiny intensified.

Spirit’s retreat has opened gaps on price-sensitive leisure routes where the two carriers overlapped. Frontier has said improved pricing in some of those markets is helping its fourth-quarter results.

Meanwhile, Allegiant Travel Co. agreed this month to acquire Sun Country Airlines Holdings in a deal valued at about $1.5 billion including debt, further reducing the number of independent budget operators focused on leisure travelers. The combined Allegiant–Sun Country carrier, still subject to regulatory review, would operate under the Allegiant brand and be headquartered in Las Vegas.

Analysts estimate ULCCs account for roughly one-tenth of U.S. domestic airline seats, while the four largest full-service and low-cost carriers—American, Delta, United and Southwest—control the bulk of capacity.

Regulatory and consumer backdrop

The operating environment is also shifting in Washington. The U.S. Department of Transportation has moved in early 2026 to soften its approach to consumer-protection enforcement, proposing greater reliance on warning letters and corrective action plans rather than large civil penalties for certain service failures.

The department has also scaled back or waived certain fines previously imposed on major carriers and abandoned a proposed rule that would have required cash compensation for passengers affected by significant delays or cancellations.

A more industry-friendly stance could reduce a cost risk for low-margin carriers like Frontier, which operate high-utilization fleets and sell a large share of seats to highly price-sensitive travelers.

A test of the low-fare model

Frontier is signaling it intends to double down on its core strategy rather than pivot away from the ULCC model.

The carrier operates from 13 bases across the United States and focuses on connecting major leisure destinations and mid-sized cities, often using secondary airports where costs are lower and congestion is reduced. It also markets its environmental efficiency, pointing to a young, fuel-efficient Airbus fleet and dense seating configuration.

Whether Dempsey can turn that formula into consistent profit after a punishing year will be closely watched by investors, regulators and travelers. A sustained turnaround could help keep fares lower in many leisure markets and preserve a budget option for cost-conscious flyers. Further setbacks could add momentum to consolidation—and potentially higher prices.

In a sector where several closest competitors are shrinking or merging, Dempsey’s challenge will be to show that an ultra-low-cost airline can do more than grow: it has to earn its way through the next downturn.
