United Airlines is significantly expanding its international network for the 2026-2027 Northern Hemisphere winter season by introducing three new nonstop routes connecting the United States with Cartagena, Colombia, and Providenciales, Turks and Caicos. The seasonal expansion strengthens the carrier’s presence across Latin America and the Caribbean while giving travelers more direct options to popular warm-weather destinations during the winter travel period.
The latest additions include new services from Houston George Bush Intercontinental Airport and Washington Dulles International Airport to Cartagena, alongside a brand-new nonstop connection between Denver International Airport and Providenciales. Together, these routes further reinforce United’s strategy of expanding leisure-focused international flying while improving connectivity across its extensive hub network.
United Airlines Adds Cartagena as Its 156th International Destination
United’s biggest announcement is the introduction of two seasonal nonstop services to Cartagena, one of Colombia’s most popular coastal cities. Beginning in December 2026, travelers will be able to fly directly from both Houston and Washington Dulles without making intermediate stops.
The Houston–Cartagena route launches on December 17, 2026, followed by Washington Dulles–Cartagena on December 19, 2026. Both routes will operate four times each week throughout the winter season using the airline’s Boeing 737 MAX 8 fleet. The aircraft accommodates between 164 and 166 passengers, offering United First, United Economy Plus, and United Economy cabins designed to serve both leisure and business travelers.
These new flights represent more than an expansion of United’s schedule. Cartagena officially becomes the airline’s 156th international destination and its 69th destination in Latin America, highlighting the carrier’s continued investment in one of the world’s fastest-growing leisure travel markets.
Cartagena Strengthens United’s Colombian Network
The addition of Cartagena complements United’s existing Colombian services to Bogotá and Medellín, giving passengers broader access to three of the country’s most important destinations. While Bogotá remains Colombia’s primary business and government center, and Medellín continues to attract visitors with its innovation and mountain scenery, Cartagena delivers a distinctly Caribbean experience.
Known for its colorful colonial architecture, UNESCO-listed historic district, vibrant culture, fresh seafood, and scenic waterfront, Cartagena has become one of Latin America’s most sought-after tourism destinations. Direct flights from two major United hubs will simplify travel for passengers throughout North America while reducing connection times compared with existing itineraries.
The expansion also reflects growing demand for premium leisure travel, particularly during the winter months when many North American travelers seek warmer climates.
Denver Receives Its First Nonstop Flight to Providenciales
United is also expanding service to the Caribbean by launching a new weekly nonstop flight between Denver International Airport and Providenciales International Airport (PLS) in Turks and Caicos.
Beginning December 19, the route will operate every Saturday through April using the larger Boeing 737 MAX 9. The schedule has been designed to maximize connectivity through United’s Denver hub, allowing passengers from across the western United States to reach the Caribbean with only one convenient connection—or nonstop for Colorado travelers.
The new service is particularly notable because United becomes the only airline offering nonstop flights between Denver and Providenciales. Previously, travelers from Colorado typically required at least one connection through another U.S. gateway before reaching the islands.
Expanding an Already Strong Presence in Turks and Caicos
The Denver service builds upon United’s established network serving Providenciales. The airline already operates year-round flights from Newark Liberty International Airport and Washington Dulles, while seasonal winter flights are available from Chicago O’Hare and Houston.
Adding Denver strengthens United’s position in one of the Caribbean’s most desirable leisure markets. The route also follows successful negotiations involving the Turks and Caicos Islands Airports Authority, which has actively pursued additional international air service to support growing tourism demand.
For travelers, the expanded network provides more flexibility, particularly for passengers originating from western states that previously lacked a nonstop Caribbean option.
New Routes Reflect Strong Winter Leisure Demand
United’s latest international expansion mirrors a broader industry trend in which airlines increasingly prioritize high-demand vacation destinations during the winter season. Rather than focusing exclusively on traditional business markets, carriers continue investing in routes serving beach resorts, historic cities, and tropical destinations that experience seasonal surges in visitor numbers.
Cartagena and Providenciales both fit this strategy perfectly. Cartagena continues to strengthen its international profile with connections across North America, Europe, Central America, and South America, while Providenciales remains one of the Caribbean’s premier luxury beach destinations with expanding airline service from multiple international carriers.
United Continues Strategic International Growth
These three new seasonal routes demonstrate United Airlines’ continued commitment to expanding its global network while capitalizing on growing leisure travel demand. By introducing additional nonstop options from major U.S. hubs, the airline improves accessibility to two highly desirable winter destinations while enhancing customer convenience.
Although all three routes are currently planned as seasonal winter services, their performance will likely influence future scheduling decisions. Strong passenger demand could support their return in subsequent winter seasons or potentially justify expanded frequencies, further strengthening United’s international footprint across Latin America and the Caribbean.
