Two of America’s most popular budget airlines are about to become one. Allegiant Air and Sun Country Airlines announced a definitive merger agreement in January 2026, confirming that Allegiant will acquire Sun Country in a cash and stock deal valued at approximately $1.5 billion. For everyday travelers who fly cheap, fly direct, and fly for leisure, this is one of the most significant airline stories in years.
The Deal in Plain Numbers
Sun Country shareholders will receive 0.1557 shares of Allegiant common stock plus $4.10 in cash for each Sun Country share they own. That works out to an implied value of $18.89 per share, representing a premium of nearly 20 percent over Sun Country’s closing price the day before the announcement. The total transaction value, inclusive of Sun Country’s net debt, comes in at about $1.5 billion.
Once the deal closes, Allegiant shareholders will own roughly 67 percent of the combined company, with Sun Country shareholders holding the remaining 33 percent. Both boards voted unanimously to approve the transaction. The deal is expected to close in the second half of 2026, pending regulatory approval.
Who Runs the Combined Airline
Allegiant CEO Gregory C. Anderson will serve as Chief Executive Officer of the merged company. Robert Neal steps into the role of President and Chief Financial Officer. Sun Country’s current President and CEO Jude Bricker will join the board of directors and serve as an advisor to Anderson during the integration period, ensuring the transition does not disrupt either airline’s operations.
Maury Gallagher, the long-serving Chairman of Allegiant’s board, will remain Chairman of the combined company. The merged entity will be headquartered in Las Vegas, where Allegiant is based, but will maintain a significant operational presence in Minneapolis-St. Paul, which has always been the heart of Sun Country’s network.
Why This Makes Strategic Sense
On paper, these two airlines are nearly perfect merger partners. Both are leisure-focused carriers. Both specialize in connecting smaller American cities to popular vacation destinations at prices that undercut the major carriers. Neither operates a traditional hub-and-spoke model or chases business travelers. They exist to get families and vacation-goers to Florida, Vegas, and beach destinations without breaking the bank.
Where they differ is in their strengths, and those differences are what make the combination so interesting. Allegiant has built one of the most extensive nonstop domestic networks in the ultra-low-cost segment, connecting hundreds of city pairs that the big airlines ignore entirely. Sun Country brings a substantial international footprint, including routes across Mexico, Central America, Canada, and the Caribbean, covering 18 international destinations that Allegiant customers could never previously reach from their home airports.
The combined airline will also benefit from Sun Country’s charter and cargo operations, which provide revenue streams that pure passenger carriers do not have. Charter flying in particular gives the merged company flexibility to deploy aircraft during off-peak periods, which has historically been one of the trickier problems for seasonal leisure airlines to solve.
What It Means for Travelers
The most immediate question most passengers will have is simple: will fares go up?
The honest answer is that consolidation in the airline industry has historically not been great for prices. When two competitors merge, there is one fewer option on any overlapping route, and basic economics suggest fares on those routes could rise over time.
That said, Allegiant and Sun Country do not overlap heavily. Their networks were built to serve different geographic regions, with Allegiant historically stronger in the Southeast, Southwest, and mid-Atlantic, while Sun Country has deep roots in the upper Midwest. Where they do not compete directly, travelers on both airlines should continue to benefit from low introductory fares and a growing number of nonstop options.
The big potential gain for travelers is on the international side. Allegiant customers in smaller cities who have never had a nonstop option to Cancun or Puerto Vallarta may find those routes opening up over time as the combined airline uses Sun Country’s existing international relationships and infrastructure to expand.
30 New Routes Already Live
Separate from the merger news, Allegiant has been aggressively expanding its domestic network throughout early 2026. The airline announced 30 new nonstop routes connecting 35 cities, including brand new service to La Crosse in Wisconsin, Philadelphia in Pennsylvania, Trenton in New Jersey, and Columbia in Missouri. Many of these routes launched in February 2026 with introductory one-way fares starting as low as $39.
Chief Commercial Officer Drew Wells explained the thinking simply. He said the airline has identified around 1,400 routes that fit its model and that population migration patterns across the US keep creating new opportunities. The expansion shows no signs of slowing down, merger or no merger.
The Financial Picture Behind the Headlines
Allegiant’s full-year 2025 financial results, released in early February 2026, gave a sense of just how much momentum the airline is carrying into this deal. The airline posted an adjusted airline-only diluted earnings per share of $5.07 for the year, delivered a 12.9 percent adjusted airline-only operating margin in the fourth quarter despite disruption from a government shutdown, and ended the year with 21 million total active members in its Allways Rewards loyalty program.
That kind of financial stability matters a great deal when attempting a merger of this size. Airlines that try to merge from a position of financial weakness tend to struggle with integration. Allegiant is entering this deal with strong margins, a growing fleet that includes new Boeing 737 MAX aircraft, and a clear commercial strategy.
What Comes Next
The deal still needs to clear US regulatory review, which could take several months. Airline mergers have faced increasing scrutiny in recent years, with regulators paying close attention to the impact on competition and consumer pricing. Given the relatively limited route overlap between Allegiant and Sun Country, observers believe the deal has a reasonable path through regulatory approval, but nothing is guaranteed until the agencies sign off.
If everything goes according to plan, the combined airline could be operational as a single entity before the end of 2026, just in time for the holiday travel season. At that point, it will rank as one of the largest leisure-focused carriers in the United States and one of the most ambitious budget airline builds in the country’s recent aviation history.
For anyone who has ever searched for a cheap direct flight and found Allegiant or Sun Country on the results page, the next year is worth paying close attention to.
