United Airlines is significantly strengthening its presence in South America by introducing new nonstop flights to Cartagena, Colombia, from both Houston George Bush Intercontinental Airport and Washington Dulles International Airport beginning 17 December 2026. The expansion marks the airline’s third Colombian destination after Bogotá and Medellín and further enhances travel options between North America and one of the Caribbean region’s most sought-after cultural and leisure destinations. Operating four weekly services from each US gateway, the new seasonal routes are designed to capture growing winter leisure demand while improving connectivity across the carrier’s extensive domestic and international network.

The launch of United Airlines Cartagena flights also reflects wider aviation trends across Latin America, where airlines continue investing in high-demand tourism markets with strong cultural appeal. Cartagena’s UNESCO-recognised colonial heritage, Caribbean coastline, cruise tourism, luxury hospitality sector and expanding international visitor numbers have made the city an increasingly attractive destination for North American travellers. With no competing airlines operating these specific routes, United gains a unique position while simultaneously broadening Colombia’s accessibility for business visitors, holidaymakers, cruise passengers and international travellers seeking seamless one-stop connections through major US hubs.

United Airlines Deepens Its Colombia Network Through Cartagena

United Airlines has steadily expanded its Colombian footprint over the past three decades, and the addition of Cartagena represents another milestone in that long-term strategy.

From December 2026, passengers will have direct access to Rafael Núñez International Airport (CTG) from two major United hubs, creating easier connections from hundreds of cities across North America.

The expansion increases destination diversity within Colombia rather than concentrating solely on traditional business gateways. While Bogotá remains the country’s principal commercial centre and Medellín continues to attract both business and leisure demand, Cartagena offers an entirely different tourism experience centred around heritage, beaches and Caribbean culture.

For travellers, this creates greater flexibility when designing multi-city Colombian itineraries.

United Airlines’ New Cartagena Operations

Both services are scheduled to operate during the Northern Hemisphere winter travel season when Caribbean leisure demand traditionally reaches its highest levels.

Why Cartagena Continues to Attract Global Tourism

Cartagena has evolved into one of Latin America’s strongest tourism brands.

Situated along Colombia’s Caribbean coast, the city combines centuries-old colonial architecture with modern luxury tourism infrastructure. Its historic walled city, military fortifications and colourful streets earned UNESCO World Heritage recognition, attracting millions of domestic and international visitors annually.

The destination appeals to multiple traveller segments, including:

• Luxury holidaymakers
• Cruise passengers
• Cultural tourists
• Beach travellers
• Wedding and honeymoon visitors
• Digital nomads
• International conference delegates

Tourism has become a major pillar of Cartagena’s local economy, supporting hotels, restaurants, transport providers, tour operators and cruise businesses.

How the New Routes Improve North American Connectivity

One of the biggest advantages of the new services lies beyond simply adding another destination.

Houston and Washington Dulles serve as major connecting hubs within United Airlines’ network.

Passengers departing from cities across the United States and Canada will now gain simpler one-stop itineraries to Cartagena without requiring additional transfers through Florida or other Latin American gateways.

Connectivity Advantages

This improved connectivity also strengthens inbound tourism into Colombia by making Cartagena more accessible from markets that previously required multiple flight segments.

Seasonal Strategy Matches Winter Leisure Demand

The timing of the launch is equally important.

December through March traditionally represents one of the busiest travel periods for Caribbean destinations.

Cold winter temperatures across North America encourage travellers to seek warm-weather escapes, while Christmas, New Year and school holidays generate substantial outbound tourism demand.

Cartagena benefits from:

• Tropical climate
• Warm sea temperatures
• Historic attractions
• Beach resorts
• Cruise arrivals
• Culinary tourism

By introducing seasonal operations rather than year-round services, United aligns aircraft deployment with periods of highest passenger demand.

Aircraft Choice Supports Medium-Haul International Growth

United has selected the Boeing 737 MAX 8 for both routes.

The aircraft has become central to the airline’s strategy for medium-haul international markets where demand is strong but does not necessarily justify larger widebody aircraft.

The aircraft also offers improved fuel efficiency compared with earlier narrowbody generations, supporting lower operating costs while reducing emissions per seat.

For airlines expanding into leisure-focused international destinations, the MAX 8 provides flexibility in balancing capacity with seasonal demand.

How United Compares with Other Airlines Serving Cartagena

Although United will enjoy exclusive operations on its two new routes, Cartagena is already well connected to several North American cities.

Nonstop North America–Cartagena Services

The addition of Houston and Washington Dulles expands geographical coverage rather than duplicating existing services concentrated in Florida or the US East Coast.

Colombia’s Tourism Industry Continues Expanding

Colombia has become one of Latin America’s fastest-growing tourism markets.

According to official tourism statistics, international visitor arrivals have recovered strongly following the pandemic, with government authorities continuing to promote tourism as a major driver of economic growth.

Investment has accelerated across:

• Airport infrastructure
• Luxury hotels
• Cruise terminals
• Convention facilities
• Heritage conservation
• Sustainable tourism projects

Cities including Bogotá, Medellín, Cartagena and Santa Marta continue attracting growing numbers of overseas visitors, particularly from North America and Europe.

Improved international air connectivity remains one of the most significant contributors to this growth.

Practical Information for Travellers Planning Cartagena Holidays

Travellers considering the new services should note several practical factors.

Cartagena experiences a tropical climate throughout the year, making it suitable for winter escapes.

Popular visitor experiences include exploring the historic Old Town, visiting San Felipe Fortress, taking island excursions to the Rosario Islands, enjoying Caribbean beaches and experiencing Colombia’s renowned gastronomy.

Travellers should also verify:

Booking early is advisable during the Christmas and New Year holiday period due to higher demand.

Broader Aviation Trends Favour Latin American Leisure Markets

United’s Cartagena expansion mirrors broader airline strategies throughout 2026.

Across the Americas, carriers continue prioritising destinations with strong leisure demand, relatively short flight times and growing international tourism.

Rather than focusing solely on traditional business markets, airlines increasingly seek routes combining holiday demand with visiting-friends-and-relatives traffic and connecting passengers.

Cartagena fits this profile particularly well.

The city enjoys strong brand recognition, increasing international hotel investment and an expanding cruise industry, making it attractive for both airlines and tourism authorities.

With these additional routes, United further strengthens its competitive position across Latin America while supporting Colombia’s broader tourism ambitions.

A Stronger Gateway Between North America and Colombia

The introduction of United Airlines Cartagena flights represents more than simply adding another international route. It strengthens Colombia’s growing role within the global tourism economy while giving travellers additional nonstop access to one of the Caribbean’s most historic destinations. For leisure visitors, cruise passengers and business travellers alike, the new services create greater flexibility, wider connectivity and improved access through two of United’s largest hubs. As airlines continue investing in high-demand Latin American destinations, Cartagena appears well positioned to benefit from increasing international visitor flows throughout the coming winter seasons.
