As of May 13th, 2026, Allegiant Air has completed its merger with Sun Country Airlines, forming the largest leisure‑focused, low‑cost carrier in the United States.
The Largest Leisure‑focused Low‑cost Carrier
On May 13th, Allegiant CEO Gregory C. Anderson spoke on the merger in a press release, “Today marks a defining moment in Allegiant’s history as we officially join forces with Sun Country to create the leading leisure-focused airline in the United States…” Under this acquisition, Allegiant anticipates close to $140 million in annual synergies over the next three years following company integration. Customer-facing staff and roles, as well as operational employees, will not change roles immediately.
The merger between both companies was announced back in January of 2026, with the deal worth about $1.5 billion including debt. The deal was approved by federal regulators, as well as shareholders of both Sun Country Airlines and Allegiant Air. The company now has a combined fleet of 195 aircraft serving 175 cities and more than 650 routes. “By bringing together two strong airlines with similar business models, we are creating a more differentiated and durable airline – one well positioned to deliver lasting value for our customers, team members, and shareholders,” Anderson explained.
What Does This Mean for Passengers?
For now, nothing has changed for passengers of either Allegiant Air or Sun Country Airlines. They will continue to operate as separate carriers. Customers can still book through the pre-existing channels they are familiar with, and easily access customer service tailored towards their specific airline of choice. Each airlines’ loyalty program—Sun Country Rewards and Allegiant Allways Rewards—will also stay unchanged, and exist separately for now. Current flight plans, schedules, and reservations are not affected by the merger.
