Delta’s running a huge sale right now from US cities like Portland (PDX), Los Angeles (LAX) and New York to all over the Caribbean. Destinations include Cabo San Lucas (SJD), Belize City (BZE), Grand Cayman (GCM) and Montego Bay (MBJ).

Right now, some of the routes we’re seeing require fewer miles than what Delta is advertising. Atlanta (ATL) to San Juan (SJU) is being priced at 36,000 miles instead of the 36,500 miles Delta advertised. First class availability isn’t bad either, as we’re seeing a nonstop New York (JFK) to Punta Cana (PUJ) for only 56,000 miles and taxes.

It’s also worth noting that there are likely other routes on sale outside of those listed. So plug in your preferred airports and see how it’s pricing. Anything below 30,000-35,000 miles round-trip is generally considered a deal.

Of course, some terms apply. You can stay at your destination a maximum of 30 days, travel dates vary (some are available as early as July while others are available in November), and you’ll need to purchase your ticket 21 days in advance. You’ll need to book directly at Delta.com.

To search, plug in your origin airport at Delta.com along with one of the sale destinations mentioned above. We recommend using Delta’s “Flexible Dates” calendar, and make sure you toggle to “Miles” when looking at search results.

TPG values each SkyMile at 1.2 cents, so 18,000 miles represents a cash equivalent of $216. If you’re in need of SkyMiles, remember that you can instantly transfer American Express Membership Rewards points to Delta at a 1:1 ratio.
