The U.S. airline industry is heading into another major shake-up. Allegiant Travel has announced it will acquire rival low-cost carrier Sun Country Airlines in a $1.5 billion cash-and-stock deal, including debt. If approved, this merger could reshape the future of budget air travel in America—especially for leisure-focused flyers.
Let’s break down what’s happening, why it matters, and what travelers and investors should watch next.
What Is the Allegiant–Sun Country Deal All About?
Allegiant, based in Las Vegas, and Minneapolis-based Sun Country both cater to cost-conscious vacation travelers, flying primarily to sun-and-beach and leisure destinations. Under the agreement:
- Allegiant will pay an implied $18.89 per Sun Country share, nearly a 20% premium over the airline’s recent closing price.
- Allegiant shareholders will own about 67% of the combined company, while Sun Country shareholders will hold roughly 33%.
- The deal includes around $400 million in Sun Country’s net debt.
- The airlines expect the transaction to close in the second half of 2026, pending regulatory approval.
Allegiant CEO Greg Anderson, who is set to lead the combined airline, called the move a way to create a “more competitive, leisure-focused airline” in the U.S.
Why This Merger Makes Strategic Sense
One of the biggest concerns with airline mergers is route overlap—but Allegiant says that isn’t an issue here. According to Anderson, the two airlines have little network overlap, which could make the deal more appealing to regulators.
Another key factor is Sun Country’s contract flying for Amazon. This cargo business adds a steady revenue stream, and Allegiant confirmed that the Amazon agreement will continue after the merger. Executives from both airlines reportedly discussed the deal with Amazon in advance—an important confidence signal.
Budget Airlines Are Under Pressure
This merger comes at a time when budget airlines are feeling the squeeze. Post-pandemic costs have surged, and domestic flight capacity has increased, putting pressure on margins.
Meanwhile, the largest U.S. airlines—Delta, American, United, and Southwest—still dominate about 70% of the domestic market, making it tough for smaller carriers to compete on pricing, routes, and scale.
By joining forces, Allegiant and Sun Country hope to gain the size and efficiency needed to survive—and thrive—in this challenging environment.
Will Regulators Approve the Deal?
That’s the big question. The proposed merger will test the Trump administration’s stance on airline consolidation.
Recent history shows mixed outcomes:
- The Biden administration blocked JetBlue’s attempted acquisition of Spirit Airlines on antitrust grounds.
- However, regulators approved Alaska Air’s nearly $2 billion purchase of Hawaiian Airlines in 2024.
Allegiant’s leadership remains confident, citing minimal route overlap and the leisure-focused nature of the business.
What This Means for Travelers
For passengers, this merger could mean:
- More efficient leisure routes and potentially better connectivity to vacation destinations
- A stronger competitor in the ultra-low-cost airline segment
- Possible changes in fares, schedules, and onboard offerings over time
As always with airline mergers, the real impact will unfold gradually after regulatory decisions and operational integration.
Bottom Line
The Allegiant–Sun Country deal signals a new chapter for U.S. budget airlines. In an industry dominated by giants and challenged by rising costs, consolidation may be the path forward. Whether regulators agree—and how travelers ultimately benefit—will be closely watched in the months ahead.
