Allegiant CEO outlines post-merger plans for MSP
Allegiant CEO Greg Anderson said the airline will limit post-merger growth at Minneapolis-St. Paul International Airport to routes with clear demand and will focus on nonstop leisure service after acquiring Sun Country in May 2026.[1]
Anderson said MSP is the primary strategic reason for the merger and will remain the combined airline's largest community, but Allegiant will add capacity only where route-level demand warrants.[1] The two carriers will keep separate brands until they receive a single operating certificate from the Federal Aviation Administration, at which point Sun Country will be folded into Allegiant.[1]
On January 11, 2026, Allegiant and Sun Country announced a definitive agreement under which Allegiant would acquire Sun Country in a roughly $1.5 billion cash-and-stock deal. Sun Country shareholders approved the transaction on May 8, and the U.S. Department of Transportation granted a key exemption on April 15 that cleared the major regulatory hurdle before closing. Allegiant closed the deal in May 2026 and will base the combined company in Las Vegas.
Allegiant has ordered 50 Boeing 737s and hired Minneapolis ad agency Colle McVoy to retain Sun Country's loyal customer base at MSP's Terminal 2.[1] MSP handled 36,071,627 passengers in calendar year 2025, and Sun Country held an 11.04% passenger market share behind Delta's 71.55%.
The mainstream summary does not mention the competitive landscape at Minneapolis-St. Paul International Airport (MSP), where the merger between Allegiant and Sun Country is expected to heighten competition among airlines. As noted by the Star Tribune, this merger raises the stakes for airline competition specifically at MSP, indicating that the implications of the merger extend beyond Allegiant's immediate operational plans. Furthermore, while the summary highlights Allegiant's focus on leisure routes, it overlooks the operational flexibility that both Allegiant and Sun Country share. According to insights from Skift, their combined model allows for quick scaling of flights based on actual demand rather than pursuing aggressive growth, a nuance that could significantly affect service offerings at MSP post-merger.
Additionally, the summary does not address Allegiant's strategic move to hire the local Minneapolis agency Colle McVoy to retain Sun Country's customer base at Terminal 2. This decision, highlighted by MSPBJnews, suggests a targeted effort to maintain loyalty among existing customers, which could be crucial in a competitive market where customer retention is key. The combined airlines will serve around 22 million annual customers with a fleet of 195 aircraft, a detail that underscores the scale of the merger and its potential impact on the local airline market.[2], Skift, MSPBJnews
