United to Launch Direct Flights from Houston and Washington Dulles to Cartagena: What This Changes for Winter Travel to Colombia

United Airlines has announced the launch of two new direct routes to Cartagena, Colombia: from Houston Intercontinental (IAH) and Washington Dulles (IAD). Flights are scheduled to start on December 17, 2026, operating four times a week, and could significantly simplify winter trips to Colombia's Caribbean coast for US tourists and passengers building itineraries through American hubs.

This news is important not just as another addition to a major airline's route network. Cartagena has long been one of Colombia's strongest tourist magnets: its historic center, Caribbean climate, cruise segment, gastronomy, nearby beach destinations, and cultural events make it a clear choice for short winter vacations. However, for many North American travelers, the trip often required connections through other cities. United's new flights from two major hubs reduce this complexity and provide the market with a more direct channel of demand precisely during the season when tourists actively seek warm destinations.

What Exactly United Announced

According to a United announcement dated June 29, 2026, the airline plans to launch non-stop flights from Houston Intercontinental Airport to Cartagena Rafael Nunez International Airport and from Washington Dulles International Airport to Cartagena Rafael Nunez International Airport. The start of both routes is scheduled for December 17, 2026. The company notes that these will be year-round routes, which will initially operate four times a week during the winter season.

In the schedule released by the carrier, flights are to operate on Tuesdays, Thursdays, Saturdays, and Sundays. A Boeing 737 is announced for these lines. For the Washington Dulles - Cartagena route, United indicates a departure from IAD at 08:20 and arrival in CTG at 13:10, with a return departure from Cartagena at 16:00 and arrival in Washington at 20:40. For Houston - Cartagena, the announced departure from IAH is 09:35 and arrival in CTG at 14:50, with a return departure at 14:20 and arrival in Houston at 17:45. At the same time, the airline explicitly warns that the schedule may change and the launch depends on government approvals.

This cautious wording is important for tourists: the route announcement does not yet mean that every date, fare, or connection will remain unchanged until December. Before booking, it is advisable to check the current schedule in the airline's system, baggage rules, minimum connection times, ticket refund conditions, and document requirements for Colombia and transit through the USA.

Why Cartagena Became a Logical Target for a New Flight

United presents Cartagena as the third point in its network in Colombia, alongside Bogota and Medellin. This is telling: the carrier is not simply adding another tourist destination, but expanding its presence in a country where it already has a long history of flights. For the passenger, the difference is significant. Bogota often serves as a business and transit center, Medellin attracts urban tourism and long-term stays, while Cartagena is a more obvious resort and cultural destination on the Caribbean coast.

The Colombian Ministry of Trade, Industry, and Tourism previously reported that in the first quarter of 2026, the country received over 1.58 million non-resident visitors, and in March, the figure grew by 6.7% year-on-year. The strengthening of international mobility and air connectivity was specifically noted as factors supporting the tourism sector. For the route to Cartagena, this is important context: new flights are appearing not in a vacuum, but against a backdrop of already noticeable demand for Colombia.

Rafael Nunez Airport itself also showed an active start to the year. According to airport data, over 335,000 passengers passed through the terminal in the first 13 days of January 2026, which was 5% more than during the same period the previous year. The administration also reported that the airport ended 2025 with 7.7 million passengers. This underscores the role of CTG as the main aerial gateway to Cartagena and one of the key hubs of tourist traffic on the country's Caribbean coast.

What Changes for US Travelers and Connecting Passengers

The most obvious change is fewer unnecessary transfers. Houston and Washington Dulles are large United hubs, meaning new flights can be useful not only for residents of Texas or the US capital region. United states that through these two hubs, Cartagena will gain connections to more than 70 destinations in the USA. For tourists, this means a wider choice of routes with a single ticket, simpler carrier responsibility for connections, and a lower risk of manually combining different airlines.

For those flying through Houston, it is useful to check the airport logistics in advance. A page about Houston Intercontinental Airport (IAH) is available on the site, and before the trip, it is also worth checking the IAH online board. If the connection is long or the flight is in the morning, hotels near Houston Intercontinental Airport or transfers from IAH may be practical. For the route through Washington Dulles, the IAD internal page could not be confirmed, so it is better to rely on official airport and airline services.

It is also important that four flights per week do not provide as much flexibility as a daily route. If a passenger plans a cruise from Cartagena, a wedding, a conference, a multi-city tour, or a complex international connection, the calendar must be checked carefully. A missed flight on a route with a frequency of four times a week can mean not just a delay of a few hours, but a restructuring of the entire trip.

Why This Is Important for Colombia's Tourism Market

For Colombia, direct flights from two American hubs are not just aviation news. This is a signal for hotels, tour operators, cruise companies, guides, restaurants, and Cartagena's urban economy. Direct access usually helps a destination compete with other winter options in the Caribbean basin: Mexico, the Dominican Republic, Jamaica, Costa Rica, or islands where American tourists have long had a large choice of non-stop flights.

Cartagena offers a different proposition than a classic beach resort. The city sells a combination of colonial architecture, port history, cuisine, music, urban walks, and short trips to islands and beach areas. That is why a direct flight can affect not only the number of tourists but also the type of travel: more short vacations of 4-5 nights, more combined itineraries with Bogota or Medellin, and more demand for premium urban hotels and excursions without a long transfer leg.

At the same time, one should not automatically expect cheaper tickets. A new route increases choice and may create competition for some traffic flows, but prices will depend on load, season, fuel costs, exchange rates, days of the week, and availability of seats in cheaper fare classes. December, holidays, early January, and school vacation periods almost always require early booking.

Documents, Safety, and Practical Checks Before Booking

The new direct flight does not change immigration rules. Entry requirements for Colombia depend on citizenship, purpose of travel, duration of stay, and itinerary. For US citizens, the State Department indicates that a tourist or business trip of up to 90 days does not require a Colombian visa, but this is not a universal rule for all passengers. Travelers with other passports, especially those flying through the USA, need to separately check Colombian rules, transit requirements, ESTA or a US visa if required for the connection.

A separate block is safety. In March 2026, the USA maintained a recommendation for Colombia at the Reconsider travel level due to crime, terrorism, civil unrest, kidnapping, and natural risks, and also highlighted specific regions that should not be visited. As of June 23, 2026, Canada advised exercising a high degree of caution in Colombia due to the crime level and had regional warnings regarding border and specific departments. This does not mean that Cartagena is closed to tourism, but it means that the itinerary should be planned without recklessness.

Practically, this comes down to several steps. Before buying a ticket, it is necessary to check current government recommendations, choose accommodation in a well-known area, order a transfer through the hotel or a verified service, avoid wearing conspicuously expensive items, avoid unofficial street taxis, have insurance with medical coverage, and understand how to act in case of flight delay or loss of documents. For beach and island excursions, it is worth checking the weather, the operator's license, and the return time to the city, especially if a flight is scheduled for the next day.

Who Will Benefit Most from the New Flights

The biggest winners are passengers who already fly the United network and can conveniently connect to IAH or IAD. These are tourists from mid-sized US cities who previously had to assemble an itinerary through other airlines or make less convenient transfers. The novelty is also interesting for travelers who want to combine Cartagena with Bogota or Medellin: United already has a presence in these Colombian destinations, and the new CTG adds a more distinct Caribbean option to the same country.

The route may also be useful for travel agencies. Cartagena sells well as a destination with a clear story: warm winter, vibrant city, shorter journey, Caribbean atmosphere without full dependence on the beach format. However, agents should honestly explain to clients the flight frequency, government approval conditions, document rules, and safety context, rather than presenting the announcement as a guarantee of a trouble-free trip.

Conclusion

The launch of United on the Houston - Cartagena and Washington Dulles - Cartagena routes could be a noticeable strengthening of winter air connectivity between the USA and the Caribbean coast of Colombia. If the flights receive the necessary approvals and start as planned on December 17, 2026, Cartagena will become easier for short vacations, cruise connections, and combined itineraries through Colombia.

For tourists, the main conclusion is simple: new direct flights add convenience, but do not cancel basic preparation. Before booking, it is necessary to check the live schedule, documents, transit through the USA, baggage rules, insurance, area of residence, official travel advisories, and connection time buffer. Then the new route can provide exactly what it was launched for: less logistics and more time in Cartagena itself.
