2 New Cheap Nonstop Flights To Cabo Officially Begin From These U.S. Cities

Share The Article

Frontier just officially flipped the switch on two new ultra-low-cost, nonstop flights to Los Cabos (SJD)—and if you live in Atlanta or Las Vegas, this is the kind of “wait… why didn’t we have this already?” travel news we love to see.

We at The Cabo Sun keep a close eye on Los Cabos’ nonstop map because new routes usually mean two things for travelers: less travel friction and more fare competition. And according to Frontier’s own route announcement, both of these new nonstops began on December 20, 2025 and are currently scheduled weekly.

The 2 new cheap nonstop routes (and what “weekly” really means)

1) Atlanta (ATL) → Los Cabos (SJD)

This is a big deal because ATL isn’t just “Atlanta.” It’s one of the easiest airports in the U.S. to connect through, which means this route can open up smoother Cabo access for a lot of the Southeast with a single stop. Frontier’s Atlanta-to-Cabo service is listed as weekly.

2) Las Vegas (LAS) → Los Cabos (SJD)

Vegas travelers, you just got a ridiculously simple beach escape. Frontier’s Vegas-to-Cabo flight also launched weekly, which is perfect for a long weekend strategy if the schedule lines up with your calendar.

How to keep these flights actually cheap

Frontier can be a steal, but only if you play it smart:

• Pack like a pro. The cheapest fares usually assume you’re traveling light. If you can do a personal item-only trip, that’s where the real savings live.
• Prepay any bags online. Waiting until the airport is where budgets go to die.
• Skip seat selection if you don’t care. If you’re not picky, letting the airline assign seats can keep the total low.
• Set fare alerts and watch Tuesdays/Wednesdays. With weekly routes, prices can jump fast when only a few flights fit your travel window.

And zooming out, these Frontier additions are one more piece of a bigger trend we’ve been tracking: Los Cabos is now so connected that travelers are getting more nonstop choices (and more chances at a deal) than ever before.

What this means for your Cabo trip planning right now

One thing we don’t want you to miss: Cabo is busy. Winter is peak season, and new flights tend to pour more people into the same high-demand weeks.

If you’re traveling in the next couple of months, read this before you book anything else.

And once you’re actually here, crowds are most noticeable in the obvious places (yes, especially the beach scene in Cabo San Lucas). If Médano Beach is on your list, these crowd-navigation tips can save you a ton of time and frustration.

Quick SJD airport reality check (so your arrival doesn’t feel chaotic)

A nonstop is only “easy” if the landing is smooth. A few practical reminders:

• Book airport transportation ahead of time if you’re arriving on a peak travel day.
• Give yourself buffer time on departure day—winter Saturdays can feel extra compressed.
• Have your basics ready (passport, any confirmations, a pen just in case) so you’re not digging through bags in line.

Bottom line

These new Frontier nonstops from Atlanta and Las Vegas are exactly the kind of “cheap and easy” Cabo access travelers have been asking for. The key is planning around the weekly schedule, packing smart so the fare stays low, and booking early if you’re traveling during peak winter weeks.

Because once you land, the only decision you should be making is: tacos first, or ocean view first?
