United Airlines has announced a major expansion of its Colombia network with the introduction of new United Airlines Cartagena flights from Houston and Washington D.C. The airline confirmed that nonstop services to Cartagena, Colombia, will begin on December 17, connecting two of its major U.S. hubs with one of Latin America’s fastest-growing coastal destinations.

The move strengthens United’s position in the region and adds a new leisure-focused gateway for American travellers seeking Caribbean-style city breaks with cultural and historic appeal. The announcement was made through official company communication and aligns with United’s broader strategy to expand its Latin America footprint.

New Nonstop Connectivity Strengthens U.S.–Colombia Air Links

United Airlines is introducing the new routes from Houston Intercontinental Airport (IAH) and Washington Dulles International Airport (IAD) to Rafael Núñez International Airport in Cartagena (CTG). The services will operate year-round, providing consistent access between the United States and Colombia’s Caribbean coast.

Route Expansion and Operational Details for Cartagena Services

• Houston (IAH) to Cartagena (CTG) begins December 17
• Washington D.C. (IAD) to Cartagena (CTG) begins December 17
• Both routes operate year-round
• Initial schedule set at four weekly flights per route
• Aircraft type planned: Boeing 737 family aircraft

These routes mark a strategic addition to United’s Latin American network, offering direct access to a destination previously reliant on connecting flights.

The airline has stated that Colombia remains a long-standing part of its international operations, supported by its existing services to Bogotá and Medellín.

Strategic Importance of Cartagena for United Airlines

Cartagena has become one of the most in-demand travel destinations in South America due to its coastal location, colonial heritage, and growing tourism economy. United Airlines’ decision to add direct flights reflects rising passenger demand between major U.S. hubs and Colombian leisure destinations.

Why Cartagena Is Becoming a Priority Route for U.S. Airlines

• Strong tourism growth driven by Caribbean coastline appeal
• Increasing demand from U.S. leisure and visiting friends and relatives (VFR) traffic
• Existing United network presence in Bogotá and Medellín
• Connectivity to more than 70 onward U.S. destinations through hub operations
• Year-round travel demand supported by business and leisure mix

The new service positions Cartagena more prominently within United’s Latin America strategy, expanding travel choices for passengers across both business and holiday segments.

Impact on Houston and Washington D.C. Aviation Markets

The introduction of United Airlines Cartagena flights is also expected to enhance the international role of both Houston and Washington D.C. hubs. Houston continues to serve as a major gateway for Latin America, while Washington Dulles functions as a key East Coast international connection point.

How the New Routes Strengthen Hub Connectivity

• Expands Houston’s Latin America network reach
• Adds new long-haul leisure destination from Washington D.C.
• Improves one-stop connectivity across U.S. domestic network
• Supports increased winter and holiday travel demand
• Enhances competition in the Caribbean tourism market

United already operates one of the largest Latin America networks from Houston, making this addition a natural extension of its regional strategy.

Broader Airline Strategy Behind the Expansion

The Cartagena launch is part of a wider trend among U.S. carriers increasing point-to-point leisure routes to high-growth tourism markets. United has been steadily expanding its international portfolio across Europe, Latin America, and select long-haul destinations.

Key Drivers Behind United’s Network Expansion

• Rising demand for nonstop leisure travel routes
• Strong performance of Latin American tourism markets
• Hub optimisation strategy across Houston and Washington D.C.
• Increased aircraft efficiency using Boeing 737 operations
• Competitive positioning against other U.S. carriers in the region

The airline has repeatedly emphasised its focus on strengthening international connectivity and offering more direct travel options from its major U.S. hubs.

Travel Demand Outlook for Cartagena Routes

The new services are expected to support growing tourism flows between the United States and Colombia. Cartagena continues to attract international visitors due to its UNESCO-listed old town, beaches, and cruise traffic.

Expected Passenger Benefits From the New Services

• Reduced travel time through direct nonstop flights
• Easier access to Caribbean coastal tourism
• Improved convenience for business and family travel
• Increased flexibility with year-round scheduling
• Enhanced connectivity through United’s hub network

The addition of these routes is likely to increase passenger volumes and further integrate Cartagena into mainstream U.S. travel itineraries.

United Airlines’ decision to launch new nonstop flights from Houston and Washington D.C. to Cartagena marks a significant expansion of its Latin American network. Starting December 17, the service will improve connectivity, support tourism growth, and strengthen two of United’s key U.S. hubs. The move reflects growing demand for direct leisure travel between the United States and Colombia’s Caribbean coast, positioning Cartagena as a more accessible destination for American travellers.
