The two airlines announced the deal Sunday, with Sun Country shareholders receiving $4.10 per share of Allegiant stock for each Sun Country share.
Combined, the two low-airfare airlines provide 22 million passengers with service to nearly 175 cities.
Minnesota-based Sun Country launched service from Gerald R. Ford International Airport in 2024 with seasonal direct flights to Minneapolis. Currently, Las Vegas-based Allegiant offers 18 direct flights from Grand Rapids.
The two companies said they will work closely with employees and their unions to ensure a smooth and transparent integration process, with existing collective bargaining agreements remaining in effect.
Allegiant expects the merger will expand its limited international service to 18 destinations.
In a release, Allegiant CEO Gregory C. Anderson stated, “We have long admired Sun Country for their well-run, flexible, and diversified business model that optimizes for year-round utilization and strong margins.”
The deal is expected to be finalized in the second half of 2026.
