Southwest Airlines Announces 2 New Direct Flights To Los Cabos

Share The Article

If you’ve been dreading that connection in Phoenix or Denver just to get to your Cabo vacation, we have massive news. The wait is finally over for travelers in two major U.S. cities.

Confirmed this week at the VIP Summit, Southwest Airlines is officially launching nonstop service from Indianapolis and Las Vegas to Los Cabos. Here is everything we know about the new routes and when you can book them.

For travelers, this isn’t just another airline announcement. It’s more proof that Los Cabos has gone from “harder to reach” to one of North America’s easiest fly-to beach escapes, with 61 international destinations now offering nonstop flights and 600+ weekly flights into SJD.

What Southwest Just Confirmed

According to Los Cabos Tourism Trust (FITURCA) director Rodrigo Esponda, Southwest used this year’s VIP Summit to move from “prospecting” to committing to new service. The airline confirmed:

• A nonstop Indianapolis (IND) – Los Cabos (SJD) route
• A nonstop Las Vegas (LAS) – Los Cabos (SJD) route

Esponda noted that one of the routes will begin in early 2026, while the Las Vegas service is planned for mid-year, alongside broader Southwest growth that also includes new flying to Alaska.

We at The Cabo Sun have already been tracking the Indianapolis news: Southwest’s Spring Break nonstop from IND to Los Cabos is scheduled to run Saturdays only from March 5 through April 6, 2026, perfect for a classic 7-night Cabo vacation.

On the Las Vegas side, Southwest’s newly released summer 2026 schedule shows the LAS–Los Cabos route starting June 4, 2026, as part of a trio of new Mexico routes out of Vegas (alongside Cancún and Puerto Vallarta).

How These Routes Fit Into Cabo’s Flight Boom

These two routes aren’t happening in a vacuum. Los Cabos has been on a connectivity tear all year:

• We just reported that 61 international destinations now fly nonstop to Los Cabos, including 32 U.S. cities, with more on the way.
• The airport now handles 600+ weekly flights, including 330 weekly operations from the U.S. alone, driven by aggressive airline growth and a major push from the tourism board.
• FITURCA has been clear that more U.S. nonstops were coming in 2026, specifically calling out Indianapolis as already locked in — which this Southwest confirmation now solidifies.
• Earlier this fall, we broke down nine new nonstop routes confirmed for 2025 across the U.S., Canada, Europe, and Panama, showing how mid-market cities and secondary gateways are finally getting their own Cabo links.

These Indy and Vegas additions are the next step in that same playbook: test seasonal, leisure-heavy routes and grow them if demand holds.

What This Means If You Fly From Indianapolis Or Las Vegas

For Indianapolis travelers:

Until now, Cabo meant at least one connection through Dallas, Denver, Phoenix, or Houston. With the new IND–SJD nonstop, you can:

• Fly Saturday to Saturday during Spring Break 2026, maximizing a full week on the ground instead of in airports.
• Pair the new Cabo flight with other recent Indy international additions, like new nonstops to Punta Cana and Dublin, turning IND into a much stronger sun-and-city gateway.

We’ve already walked through how this schedule works and how to build the perfect 7-night itinerary in our earlier breakdown on Americans finally getting a nonstop to Los Cabos from Indianapolis — a great starting point if you’re planning around school calendars or limited PTO.

For Las Vegas travelers:

Southwest’s LAS–Los Cabos flight plugs one of the most obvious gaps in Vegas’s leisure map. Beginning June 4, 2026, Cabo will join Cancún and Puerto Vallarta as part of an expanded international push from Harry Reid International.

For you, that means:

• Easy long-weekend escapes: Vegas to Cabo is a quick hop, opening up 3–4 night trips that feel more like a “bonus vacation” than a big yearly blowout.
• Smoother connections: If you’re connecting via Vegas from cities that don’t yet have Cabo nonstops, this new SJD link could become your most efficient route.

Will These Flights Make Cabo Cheaper?

More seats usually equal more competition — and that’s already happening in Los Cabos. The destination has seen an explosion of new services from carriers like Southwest, Volaris, WestJet, Copa, and Condor, all chasing surging demand.

In our recent report on 600+ weekly flights into Los Cabos, we explained how overlapping routes often trigger short-term fare deals, especially when low-cost carriers or aggressive players like Frontier or Viva Aerobus enter a market.

Southwest in particular already stands out as one of the cheapest ways to reach Cabo from many U.S. cities, thanks to its point-to-point network and strong presence in markets like Phoenix, Houston Hobby, Denver, Chicago Midway, Baltimore, San Diego, and San Jose. Adding Indy and Vegas only increases the odds of sale fares and competitive responses from rival airlines.

How To Take Advantage Of The New Routes

Here’s how we at The Cabo Sun recommend playing this:

1. Watch the schedule closely. Southwest’s seasonal Indy–Cabo flights and the June 4 launch of Las Vegas–Cabo are already in published schedules, but exact times and days can still shift. Always verify your dates directly with the airline before locking in hotels.
2. Plan around Saturdays from Indy. With once-weekly service, those seats will go fast for prime Spring Break weeks. If you can be flexible, target the first or last week of the season for better prices and availability.
3. Use Vegas as a strategic hub. Even if you don’t live in Nevada, routing through LAS can open up more options and sometimes cheaper itineraries once the new nonstop is live.
4. Compare airlines, not just cities. Our earlier breakdown of nine new nonstops for 2025 and our coverage showing the airport is more connected than ever walk through how to leverage all these new gateways — even if you never actually fly them.

The bottom line: Southwest’s new nonstops from Indianapolis and Las Vegas are another sign that Cabo’s flight map is only getting stronger. If you’ve been waiting for an easier, faster way to trade your work shoes for flip-flops, 2026 might be the perfect year to finally make that Los Cabos trip happen.
