United Airlines is making it significantly easier to swap the winter chill for the vibrant, sun-drenched streets of the Colombian Caribbean.
In a major expansion of its Latin American network, United Airlines has officially announced the launch of brand-new, nonstop service to Cartagena, Colombia (CTG) from two of its premier U.S. hubs: Houston George Bush Intercontinental Airport (IAH) and Washington Dulles International Airport (IAD).
Cartagena marks United’s 69th destination in Latin America and complements its existing Colombian footprints in Bogotá (BOG) and Medellín (MDE). The new routes are perfectly timed for the peak winter travel season, offering travelers a direct gateway to the historic Walled City, fresh coastal seafood, and pristine beaches without the hassle of a connection.
The Flight Schedules and Frequencies
Both new routes will launch this December, operating four times per week throughout the winter season. United will deploy its modern, fuel-efficient Boeing 737 MAX 8 aircraft on these routes, featuring upgraded interior cabins, larger overhead bins, and seatback entertainment at every milestone.Here is the operational breakdown for the new service:
- Houston (IAH) to Cartagena (CTG): Nonstop service officially lifts off on December 17, 2026, flying 4x weekly.
- Washington Dulles (IAD) to Cartagena (CTG): Nonstop service begins just two days later on December 19, 2026, also flying 4x weekly.
By adding Washington Dulles alongside Houston, United is giving East Coast travelers a massive advantage, drastically reducing travel time to northern Colombia compared to standard connections through Florida or Bogotá.
Strengthening the Hub Networks
This announcement highlights United’s strategic play to dominate long-haul and leisure connectivity out of its core strongholds. Houston (IAH) continues its reign as United's primary launchpad for Central and South America, while Washington Dulles (IAD) expands its role as a premier dual-purpose hub capable of anchoring major transatlantic and neotropical leisure routes alike.For frequent flyers looking to maximize their MileagePlus miles, the addition of Cartagena opens up premier award ticket availability on a highly sought-after Caribbean route just as holiday demand spikes.
