United Airlines is making Colombia’s Caribbean coast easier to reach for US travellers with a new nonstop Houston–Cartagena route launching on December 17, 2026. The new service will operate four round trips every week, giving passengers a faster connection to Cartagena’s UNESCO-listed historic centre, beaches and cultural attractions without needing to connect through another Colombian city. The move strengthens US–Colombia travel links and opens a new gateway for holidaymakers, business travellers and visitors seeking a simpler way to explore one of South America’s most popular coastal destinations.

The new route will connect Houston George Bush Intercontinental Airport (IAH) with Cartagena Rafael Núñez International Airport (CTG), expanding United Airlines’ Latin America network and creating another direct travel option for passengers from across the United States.

Why This Matters for Travellers

The launch of United Airlines Houston Cartagena flights gives travellers a more convenient way to experience Colombia’s Caribbean region. Cartagena has become a major international tourism destination, attracting visitors with its historic streets, colonial architecture, Caribbean beaches and vibrant cultural scene.

For many US travellers, reaching Cartagena currently requires a connecting flight through another Colombian city. The new nonstop service will simplify journeys and reduce travel time, making short holidays and longer cultural trips easier to plan.

Key Benefits for Travellers Choosing the New Route

• Direct access to Cartagena: Passengers can fly directly from Houston to Colombia’s Caribbean coast without an additional domestic connection.
• Greater travel convenience: Families, leisure travellers and business passengers can enjoy a simpler journey with fewer airport transfers.
• Improved US-Colombia connectivity: The route strengthens links between one of the United States’ major aviation hubs and a key Colombian tourism destination.
• More holiday opportunities: Travellers can explore Cartagena’s beaches, historic landmarks, local cuisine and Caribbean experiences more easily.

The new service is expected to support growing demand for international travel between North America and Latin America while giving travellers more flexibility when planning Colombia trips.

What Has Changed With United Airlines’ Colombia Network

United Airlines continues to expand its presence in Colombia by adding Cartagena to its existing network. The airline already operates services connecting the United States with major Colombian cities, and the new Houston route adds a direct link to the country’s Caribbean coastline.

Cartagena’s addition strengthens United’s international network from Houston, one of the airline’s largest hubs with connections to numerous domestic and international destinations.

How the New Houston Cartagena Service Works

The flights will operate through United Airlines’ Houston hub, allowing passengers from different parts of the United States to connect easily before continuing to Cartagena.

Houston’s position as a major aviation gateway means travellers from cities without direct Colombia services may also benefit from the new route through connecting flight options.

• International visitors can use Houston as an entry point before reaching Colombia’s Caribbean coast.
• Colombian residents and overseas communities gain another direct travel option between the two regions.

The additional connectivity could also help support tourism businesses in Cartagena, including hotels, restaurants, cultural attractions and local experiences.

Cartagena’s Growing Appeal for International Travellers

Cartagena has become one of Colombia’s most recognisable destinations, combining history, culture and coastal experiences. The city’s fortified old town, colourful buildings and Caribbean atmosphere continue to attract visitors from around the world.

The destination offers a mix of heritage tourism, beach holidays, cruise visits and culinary experiences, making it attractive to different types of travellers.

Experiences Travellers Can Discover in Cartagena
