Southwest Airlines will begin daily nonstop service between Las Vegas and Los Cabos on June 4, 2026. The 948-mile route marks the carrier’s first international flights from Harry Reid International Airport and will run through early 2027. Tickets are already on sale at Southwest’s website.
Los Cabos will join Cancún as a same-day launch destination from Las Vegas on June 4. A third Mexico route, Las Vegas to Puerto Vallarta, will follow in October with weekend-only service on Saturdays and Sundays. All three routes are part of a broader international push by Southwest targeting key Mexican beach markets.
Competing With Alaska Airlines on the Western Corridor
The new Las Vegas to San José del Cabo (SJD) route puts Southwest in direct competition with Alaska Airlines, which has long held a dominant position in the Western U.S. to Mexico corridor. More carriers on the route could push fares lower, particularly during shoulder seasons when competition for seats is fiercest.
Southwest is also adjusting its existing Los Cabos network as part of the expansion. The airline’s Kansas City to Los Cabos service will be suspended through the third quarter of 2026, with a planned return in October. Oakland to Los Cabos service is expected to resume in November. A seasonal Saturday-only nonstop from Indianapolis to Los Cabos launched in March and runs through April 6, 2026.
What This Means for Los Cabos Travelers
For travelers without a direct flight to SJD from their home city, Las Vegas now becomes a practical connecting point. Harry Reid International handles flights from dozens of U.S. cities, and the daily frequency of the new Cabo route makes same-day connections more feasible than a weekend-only schedule would allow.
One change to keep in mind: Southwest no longer offers free checked bags. Travelers booking the new route should factor luggage fees into their total cost when comparing fares with Alaska and other carriers already serving the Las Vegas to Los Cabos market.
Southwest’s seven new international routes for the third quarter of 2026 include four already operating, the two Las Vegas launches on June 4, and the Puerto Vallarta addition in October. The expansion comes even as the airline industry faces pressure from rising fuel costs that have prompted route cuts elsewhere.
