Frontier Group Holdings and Spirit Aviation Holdings are in active merger discussions as of December 17, 2025. Spirit is in Chapter 11, having filed its second bankruptcy in August 2025, and has secured a $100 million lifeline to keep operations running. Frontier recently appointed James Dempsey as interim CEO after Barry Biffle’s abrupt exit on December 15.
The talks aim to combine Frontier’s cost discipline and growing loyalty program with Spirit’s extensive route network, potentially creating the fifth‑largest U.S. carrier. For Spirit, a merger offers a path out of bankruptcy; for Frontier, it could expand market reach and deliver synergies in fleet utilization, procurement, and ancillary revenue.
Spirit reported a Q4 2023 net loss of $183.7 million ($1.68 per diluted share) on $1.3 billion in revenue, a 5% year‑over‑year decline. Frontier’s Q3 2025 net loss was $77 million ($0.34 per share) on $886 million in revenue, 4% lower capacity. Both airlines face cost inflation and competitive pricing pressures, underscoring the urgency of a strategic transaction.
Following the announcement, Frontier’s stock rose 7.5% to 9% in pre‑market trading, reflecting investor optimism about consolidation and potential cost synergies. Analysts noted that the merger could improve Frontier’s scale and resilience against legacy carriers offering basic‑economy fares.
Frontier’s interim CEO James Dempsey emphasized the company’s focus on operational efficiency and strategic growth. Spirit’s President and CEO Ted Christie highlighted the need for a strategic transaction to restore profitability, noting that the company’s transformation plan positions it for a stronger future.
While the talks are still in early stages, both companies have expressed confidence that a deal could close within the year. The merger would create a more competitive ULCC platform, but regulatory approval and integration challenges remain.
