Allegiant Travel Company completed its acquisition of Sun Country Airlines Holdings on May 13, 2026, closing a deal that brings together two carriers built around affordable leisure travel. The companies said the transaction finished after customary closing conditions were met, including regulatory approvals and shareholder approval from both airlines.

Gregory C. Anderson said the combined fleet has 195 aircraft serving nearly 175 cities, and the company said it will serve about 22 million annual customers across more than 650 routes. In his remarks, Anderson called the deal a defining moment for Allegiant and said the combination creates a more durable airline with broader reach and more destinations for travelers.

For customers, the immediate effect is limited. Travel can still be booked through existing channels, and there are no changes to current reservations, flight schedules or travel plans. Allegiant and Sun Country will continue to operate as separate carriers in the near term, and their rewards programs, Allegiant Allways Rewards and Sun Country Rewards, will remain separate for now.

The deal gives Allegiant a larger footprint in the U.S. leisure market at a time when low-cost travel remains a clear demand driver. Allegiant said the combination strengthens its position as a leading U.S. leisure airline, while also creating room to expand access across the combined network over time.

The companies also said the transition will not bring immediate changes for frontline workers, and all existing collective bargaining agreements will stay in place. At the same time, some corporate roles may overlap as the two businesses are integrated, a reminder that the clean public message of continuity sits alongside the harder work of combining two airlines behind the scenes.

Allegiant expects Minneapolis-St. Paul to remain an important operating center for the combined company, signaling that the Sun Country base will keep a central role as integration moves forward. The next phase is less about the closing itself than about whether the airline can turn two similar business models into a single operation without disrupting the travelers and workers it says it wants to keep close.
