JetBlue has committed to sell all Spirit Airlines holdings in Boston and Newark to Allegiant Air as part of the ongoing merger between JetBlue and Spirit Airlines.

In a major industry move on January 11, 2026, Allegiant Air announced a definitive merger agreement to acquire Sun Country Airlines. The deal, valued at approximately $1.5 billion, aims to combine Allegiant's strength in small-to-mid-sized underserved markets with Sun Country's diversified business model, which includes scheduled leisure service, charter flights, and cargo operations for Amazon. The combined airline remains focused on low-cost leisure travel, offering over 650 routes across the United States, Mexico, Central America, Canada, and the Caribbean. This merger significantly expands Allegiant's footprint, particularly in Minneapolis-St. Paul (Sun Country’s primary hub), and integrates Sun Country’s two million loyalty members into Allegiant’s larger "Allways" rewards ecosystem. The acquisition is intended to create a more competitive leisure-focused carrier capable of better utilizing aircraft year-round and providing expanded international destinations to travelers from smaller regional airports.
