United Airlines will launch nonstop service between Washington Dulles and Los Cabos International Airport starting October 25, 2026, giving the Washington DC area its first direct link to the Baja California Sur resort region. The route runs on a Boeing 737 narrowbody aircraft with four weekly departures.
Schedule and frequency
The new route operates Mondays, Thursdays, Saturdays and Sundays at launch, with United scaling the schedule up to daily service during the December peak holiday period. Outbound flights depart Washington Dulles at 8:30 a.m. and arrive in Los Cabos at 12:08 p.m. local time, while the return flight departs Los Cabos at 1:20 p.m. and arrives back in Washington at 7:58 p.m.
Why the timing matters
Late October marks the start of Los Cabos’s high season, when drier weather and cooler evening temperatures draw more visitors than the hot, humid summer months. Launching five days ahead of the November high season ramp up positions the new route to capture early season demand rather than arriving mid season after travel plans are already locked in.
Part of a wider United expansion into Mexico
The Dulles to Los Cabos route is one of several Mexico focused additions United scheduled for the northern winter 2026 and 2027 season, alongside a new Houston to Tuxtla Gutierrez route in Chiapas starting around the same window. With the Dulles connection in place, San Jose del Cabo becomes the second Mexican destination, after Cancun, to be simultaneously connected to all seven of United’s major US hubs, including Chicago, Denver, Houston, Los Angeles, Newark, San Francisco and now Washington.
United’s other Mexico route this season
Alongside the Los Cabos route, United is launching a new Houston to Tuxtla Gutierrez service in Chiapas starting around the same window, part of the same broader round of Mexico focused network additions for the airline’s winter 2026 and 2027 schedule. Tuxtla Gutierrez serves a different kind of traveler than Los Cabos, primarily business and visiting friends and relatives traffic rather than resort leisure demand, but both routes reflect United’s wider push to add Mexican destinations across its network this season.
Who the new route is likely to serve
A once to four times weekly leisure focused route like this one tends to draw a mix of resort travelers booking ahead for the winter season and repeat Los Cabos visitors who previously had to connect through another United hub. The scaling to daily service in December specifically targets the holiday travel period, when demand from the Washington DC area to warm weather destinations is at its highest.
Dulles as a Caribbean and Mexico gateway
Washington Dulles already serves as one of United’s secondary hubs for Caribbean and Mexico leisure routes, alongside longer established service to destinations like Cancun and Punta Cana. The new Los Cabos route extends that existing leisure network on the Pacific side of Mexico, giving Washington area travelers a wider spread of warm weather options from a single hub rather than needing to connect through Houston, Denver or another West Coast gateway specifically for Los Cabos.
Aircraft and onboard experience
United is deploying a Boeing 737 narrowbody on the route rather than a widebody aircraft, which is standard for a flight of this distance and keeps operating costs down on what is initially a four times weekly schedule. Seating includes United’s standard domestic configuration with a first class cabin, Economy Plus extra legroom seating and standard economy, rather than the lie flat seating found on some of United’s longer international routes.
What this means for travelers booking a Los Cabos resort trip
A new nonstop option generally puts downward pressure on fares over time as competing airlines and connecting itineraries adjust, though first season pricing on a brand new route does not always reflect where fares settle once the route is established. Travelers based in the Washington DC metro area booking a Los Cabos all-inclusive for next winter now have a nonstop option where a connection, usually through Houston or Los Angeles, was previously the only choice on United specifically.
Los Cabos versus other Mexican resort regions
Los Cabos differs from Mexico’s Caribbean coast resorts in both climate and landscape, trading the Caribbean’s turquoise water and coral reefs for a desert backdrop, dramatic rock formations at Land’s End, and a drier climate overall.
