United Airlines is significantly expanding its presence in Colombia by launching two new nonstop routes to Cartagena, one of the country’s fastest-growing leisure destinations. Beginning December 17, 2026, the airline will introduce year-round flights from Houston George Bush Intercontinental Airport and Washington Dulles International Airport, providing travelers with more convenient access to Colombia’s historic Caribbean coastline. The expansion reflects United’s continued commitment to the Latin American market while responding to changing travel demand and shifting airline competition.

The new services arrive at a pivotal moment for the U.S.-Colombia aviation market. While the industry has experienced a reduction in overall capacity following Spirit Airlines’ exit, major carriers such as United, Avianca, and American Airlines are stepping up investments across key Colombian destinations. Cartagena, known for its colonial architecture, pristine beaches, luxury resorts, and vibrant cultural attractions, is expected to benefit significantly from improved connectivity, attracting both leisure travelers and international tourism.

United Airlines Introduces Two New Nonstop Cartagena Routes

United Airlines will begin operating nonstop flights from two major U.S. hubs to Cartagena on December 17, 2026. Both routes will operate four times each week during the winter schedule using Boeing 737 aircraft.

The launch makes Cartagena United’s third destination in Colombia after Bogotá and Medellín, strengthening the airline’s long-standing presence in the South American country.

Cartagena Becomes a Bigger Tourism Gateway

Cartagena continues to establish itself as one of Latin America’s premier leisure destinations. The UNESCO-recognized historic city attracts visitors seeking Caribbean beaches, colonial landmarks, luxury hotels, cultural festivals, and cruise tourism.

United’s new nonstop services provide easier access for American travelers while creating stronger connections through Houston, one of the airline’s largest Latin American hubs. The Washington Dulles route is particularly notable because it establishes United’s first nonstop service between the U.S. capital region and Colombia.

Improved connectivity is expected to support inbound tourism, business travel, and regional economic development.

U.S.-Colombia Aviation Market Undergoes Major Changes

The competitive landscape between the United States and Colombia has shifted considerably in 2026 following the collapse of Spirit Airlines.

Although total nonstop capacity has declined slightly, established network carriers are filling much of the gap by expanding services across important Colombian markets.

Spirit’s exit has opened new opportunities for legacy airlines to strengthen their market positions.

Avianca and American Airlines Continue Expanding

While United adds Cartagena to its network, other airlines are also increasing their investments in Colombia.

Avianca has emerged as the largest beneficiary of the changing competitive landscape, expanding its U.S.-Colombia capacity by more than 17% and capturing nearly half of the market. American Airlines has also increased available seats across several routes.

United’s slight reduction reflects lower capacity on its Houston–Medellín service rather than an overall retreat from Colombia.

Cartagena Faces Lower Capacity Despite New Routes

Despite United’s announcement, overall U.S.-Cartagena capacity remains below last year’s levels due primarily to Spirit Airlines’ withdrawal from the market.

Existing U.S. airlines serving Cartagena include American Airlines, Delta Air Lines, and JetBlue Airways, while Miami remains the city’s largest international gateway from the United States.

Total U.S.-Cartagena capacity is projected to decline by approximately 20.4% during the 2026 summer season compared with the previous year.

Colombia’s Leading International Gateways

Bogotá continues to dominate international air travel between Colombia and the United States, while regional markets display varied performance.

Barranquilla has recorded the strongest growth, largely driven by expanded Miami services.

What United’s Expansion Means for Travelers

The addition of nonstop flights offers greater flexibility for travelers from both Texas and the U.S. East Coast. Passengers will benefit from shorter travel times, expanded connecting opportunities through United’s domestic network, and easier access to Colombia’s Caribbean tourism region.

For Cartagena, the new services are expected to stimulate international tourism, strengthen hospitality demand, and support continued economic growth as global travel continues its post-pandemic evolution.
