United Airlines announced it will begin nonstop flights from Houston Intercontinental Airport (IAH) and Washington Dulles International Airport (IAD) to Cartagena, Colombia (CTG), starting December 17.
The carrier will be the first U.S. airline to operate year-round direct service between these U.S. hubs and Cartagena, with flights scheduled four times per week from both locations.
Flights will initially operate on Tuesdays, Thursdays, Saturdays, and Sundays. Departures from Washington Dulles are set for 8:20 a.m. with arrival in Cartagena at 1:10 p.m., while return flights depart Cartagena at 4:00 p.m. and arrive at Dulles at 8:40 p.m. From Houston, flights will depart at 9:35 a.m. and arrive in Cartagena at 2:50 p.m., with return flights leaving Cartagena at 2:20 p.m. and arriving in Houston at 5:45 p.m. All flights will be operated with Boeing 737 aircraft.
United stated that onboard amenities will include seatback screens with Bluetooth connectivity, larger overhead bins, and—soon—free Starlink Wi-Fi for MileagePlus members. Tickets for the new routes are now available through the airline’s website and app.

The new service expands United's Colombia network, which already includes flights to Bogotá and Medellín. The airline has served the country for over 30 years.
"Colombia has been an important part of United's Latin America network for more than 30 years, and our new service to Cartagena reflects our continued investment in the country and commitment to offering customers new and distinct travel experiences," said Patrick Quayle, Senior Vice President of Network Planning and Global Alliances, United Airlines.
According to United, the Cartagena routes will connect to more than 70 destinations across the U.S. from its Houston and Washington hubs. The schedule is subject to change pending government approval.
