Is Costa Rica on your travel wishlist? Heres your chance to get there for less than the cost of most domestic flights using Delta SkyMiles.

We recently unearthed this unadvertised Delta SkyMiles flash sale with flights to Liberia, Costa Rica (LIR) as low as just 16,000 SkyMiles roundtrip and rates below 29,000 SkyMiles from dozens of airports! This is your chance to fly down to the beaches and rainforests of Costa Rica for a fraction of what other airlines charge. You can book these flights through the winter and even into the spring peak spring break season!

Thrifty Traveler Premium subscribers got this deal earlier this week as soon as we found it, so some of the cheapest availability has been snapped up already. Still, you can find some great deals, give or take a few thousand SkyMiles especially for a trip in March and April. Travelers with a co-branded Amex card will see the lowest rates thanks to the automatic 15% discount on Delta award tickets.

You can find cheap award flights down to Costa from February through April 2024 thanks to this deal. And lucky you, youll find the best availability in March and April, prime time for a spring break getaway. And while these award flights get hit with around $79 or so in taxes and fees, thats a small price to pay on an otherwise great and cheap winter escape.

But the best part about this deal is how widespread it is: You can book at discounted SkyMiles rates from dozens of airports, big and small, across the country. Even major Delta hubs like Minneapolis-St. Paul (MSP) and Atlanta (ATL) are getting in on the action no Delta hub penalty here! Keep reading for the full list of cities!

Youll see the lowest rates are for Delta basic economy award tickets, which dont come with free seat assignment, and get hit with a 9,900-SkyMile penalty if you want to cancel to get the rest of your miles back. These fares also dont count toward Delta Medallion Status, unlike most award fares booked with SkyMiles.

So it could easily be worth spending a few thousand extra SkyMiles for a main cabin economy fare, as those tickets are fully refundable: Get your miles and taxes and fees back for free! It varies by route, but you can generally expect to pay another 8,000 to 18,000 SkyMiles or so for a main cabin fare.

This is just one of several Delta SkyMiles flash sales weve seen recently. Not feeling Costa Rica? For the same number of miles, you could plan a warm-weather getaway to the Caribbean instead.

Just a few days after finding these dirt-cheap SkyMiles rates to Costa Rica, we sent our Thrifty Traveler Premium subscribers this flight deal to Montego Bay, Jamaica (MBJ) from 16,000 SkyMiles roundtrip!   

And a week ago, we found a similar deal flying directly into the new Tulum (TQO) airport for under 25,000 SkyMiles from dozens of airports around the country big and small, whether youre flying nonstop or making a connection.
