In a dynamic reshaping of Orlando International Airport (MCO), Southwest Airlines is joining forces with Frontier, United, and Delta Airlines to overhaul the airport’s route network in the wake of Spirit Airlines’ exit. This significant shift presents an exciting growth opportunity and reflects a pivotal moment for air travel in the United States.
With the recent departure of Spirit Airlines, a prominent player in the budget travel sector, Orlando’s aviation landscape faced both challenges and opportunities. The exit left a considerable gap in the airport’s capacity, prompting the remaining airlines to swiftly adapt and expand their service offerings. Southwest, Frontier, United, and Delta are stepping up to not only fill this vacuum but also significantly enhance their presence at MCO:

The closure of Spirit Airlines, known for its low-cost travel options, was a notable event, resulting in over 1,000 flight cancellations. This disruption had an immediate impact on leisure travel, particularly those traveling to visit family and friends. The Greater Orlando Aviation Authority (GOAA) quickly mobilized to mitigate the impact, collaborating with major airlines to stabilize operations and prevent a further decline in passenger numbers.
In response, MCO saw a rapid escalation in activity from its largest carriers. Southwest Airlines, already the airport’s leading airline, expanded its route portfolio, introducing new destinations and increasing flight frequencies to match the influx of displaced travelers.
Among the first to seize the growth opportunity was Southwest Airlines, which commenced a major expansion at MCO. In 2026, Southwest launched six new nonstop routes to vibrant locations such as St. Thomas and St. Martin, aligning with Orlando’s status as a premier leisure destination. Additionally, the airline expanded its domestic network with new flights to cities like San Jose, California, and Knoxville, Tennessee.
Not stopping at new routes, Southwest’s strategy also includes a significant increase in daily departures, aiming to serve over 200 flights by 2027. This commitment not only enhances Southwest’s presence in Florida but also supports the state’s crucial tourism sector.

As Southwest bolstered its offerings, Frontier Airlines quickly laid claim to Spirit’s former customer base. With new routes to destinations like Pensacola, Florida, and Salt Lake City, Frontier has solidified its position as a major low-cost carrier at MCO. Their focus on regional connections and major hubs has proven timely and strategic.
Furthermore, Frontier has resumed critical international routes to Latin America, including daily service to San Jose, Costa Rica, showcasing an aggressive approach to expand year-round international connectivity.
The exit of Spirit Airlines has also sparked renewed activity from legacy carriers such as United Airlines and Delta Air Lines. United announced 15 new daily round-trip flights starting January 2026, expanding service to essential sunbelt cities like Houston and Newark as it adapts to the growing demand for leisure travel.
Delta has been proactive as well, by increasing its transcontinental services and resuming year-round flights to key international destinations, including Amsterdam, thus positioning itself to cater to both leisure and business travelers.
In this rapidly evolving air travel scene at MCO, regional carriers like JetBlue and Breeze Airways are also making their mark. JetBlue is enhancing intra-Florida services, such as the newly launched nonstop flights between MCO and Fort Lauderdale. Breeze Airways has focused on regional connectivity, offering personalized service to underserved markets like Pensacola and Brownsville, Texas.
The international reach of Orlando International Airport is expanding significantly, with new services to Europe and Latin America. TAP Air Portugal announced a new nonstop route to Lisbon, while various carriers are enhancing services to Mexico. This growth not only solidifies Orlando as an international gateway but also strengthens ties to global markets.

To accommodate the resultant passenger influx, the Greater Orlando Aviation Authority (GOAA) has embarked on a $5.9 billion capital improvement plan. This strategic investment will modernize airport facilities, enhance passenger experiences, and expand parking capacity. Additionally, upgraded security technologies will streamline processes, ensuring that passengers enjoy a world-class travel environment.
With Spirit Airlines’ exit acting as a catalyst, the transformation of Orlando International Airport signifies a fresh chapter in Central Florida’s aviation landscape. As major airlines like Southwest, Frontier, United, and Delta expand their operations, MCO stands poised to become an even more vital hub for air travel. Continuous upgrades to infrastructure and an expanding network of domestic and international flights bode well for the future of Orlando’s aviation sector.
