Allegiant Airlines Halts Flights to Five U.S. Airports

LAS VEGAS, Nevada — Allegiant Airlines has announced the suspension of flights to five major U.S. airports: Baltimore, San Antonio, El Paso, Grand Junction, and Gulfport. This strategic move, which takes effect immediately, aims to streamline operations as the airline refocuses its resources on more profitable routes amid changing market dynamics.

With the cancellation of these flights, all booking options to the affected cities have been removed. This decision comes as Allegiant faces increasing competition and seeks to optimize its route network.

Allegiant Airlines, known for providing low-cost travel options, first began serving Baltimore/Washington International Thurgood Marshall Airport in 2016, expanding its operations over the years. However, its last flight from Baltimore occurred in December 2024. A spokesperson from the airline explained, “We’re continuously evaluating our route network to ensure sustainability and profitability.”

The airline’s operations in El Paso were also relatively brief, originating in 2016. Despite initial offerings to popular destinations, Allegiant’s last scheduled service from El Paso ended in January 2025. The city’s limited passenger demand was cited as a contributing factor to the suspension.

Grand Junction, Colorado, has been part of Allegiant’s portfolio for 13 years, linking the city to larger hubs. However, Allegiant ceased operations there in January 2025 due to challenges maintaining profitability in light of low demand. Local travel expert Sarah Thompson noted, “Grand Junction has always been a tricky market for airlines due to its size.”

Despite its shorter tenure, Allegiant had also briefly served Gulfport-Biloxi International Airport, initiating operations in 2017 and offering seasonal routes before ceasing all service in August 2024.

Perhaps the most significant impact is felt in San Antonio, Texas. Allegiant entered this competitive market in 2015 but suspended service last August, citing increased competition as a reason for reevaluation of their operations. San Antonio now faces the gap left by Allegiant’s departure, potentially allowing other airlines to introduce new routes.

The suspension of flights to these five airports marks a significant alteration in Allegiant’s approach to its route offerings. In recent years, the airline has refocused its strategy to prioritize more lucrative markets, evidenced further by its recent closure of the Los Angeles base after 16 years of operations.

Passengers who had tickets booked with Allegiant will need to consider alternative travel arrangements, which could lead to increased fares or more limited options given the airline’s role as a low-cost competitor.

“Allegiant’s decision is a reminder of how quickly the airline industry can change and how important it is to be adaptable,” said industry analyst Mark Adams. “For travelers, it’s a disruption, but it might also open up opportunities for other airlines in these markets.”

As Allegiant shifts its focus to other regions, travelers in Baltimore, San Antonio, El Paso, Grand Junction, and Gulfport will be left navigating a landscape that may change significantly in the coming months.
