Whether you’re a recent convert to points and miles or a seasoned pro, you’ve heard the knock on Delta SkyMiles: They’re “worthless,” “unpredictable” and “not worth the trouble.” Let the Thrifty Traveler team set the record straight: That’s all wrong.

Sure, it’s a tricky program with some major challenges and a history of sudden price hikes that make your stash of SkyMiles less valuable. But that doesn’t mean that they’re useless – far from it.

We’ll outline some of our best tips for understanding Delta SkyMiles and redeeming them for maximum value.


Rules of Thumb

The main thing you need to understand about Delta’s loyalty program is that the guidelines that govern most frequent flyer programs don’t really apply to SkyMiles. That’s because Delta long ago stopped publishing an award chart. Most airlines use an award chart to set the base amount of miles charged for any given award flight.

Instead, Delta uses a highly variable award system that looks more like a cash fare calendar, changing based on demand, seats sold, time of year, price of the flight, and so on.

And while most airlines have two or three price tiers at which they offer award fares, Delta has five or more. So even on the exact same route, the amount of SkyMiles charged for a flight can vary wildly day by day.


Get A Long View

Without an award chart, using Delta’s calendar view of award fares is the key to getting the best bang for your buck with SkyMiles. Once you’ve zeroed in on your route, use the “flexible days” search function, then look for five weeks of availability.

Scrolling through a few months, you’ll get a feel for what the absolute base price is for a given award fare, like the 37,000 SkyMiles it will take you to get from Minneapolis-St. Paul (MSP) – or any Delta hub – to London-Heathrow (LHR) in economy.

Thrifty Tip #1: Ensuring you’re getting your flights for the lowest amount of SkyMiles possible is the key to getting the most out of Delta’s program.

Sweet Spot for Short Flights

We’ve cautioned against using your miles for domestic flights in our guide on when to use points vs. paying cash, but it’s an area where SkyMiles actually shine.

There is no shortage of routes available for between 5,000 and 10,000 SkyMiles each way. Seattle (SEA) to Denver (DEN) for 5,000, Minneapolis-St. Paul (MSP) to Boston (BOS) starting at 7,000 SkyMiles and even the highly competitive route between San Francisco (SFO) and New York City-JFK (JFK) for as low as 9,000 SkyMiles.

The trick is finding them at the lowest price tier, as you learned above. When you can, it’s a win, considering American and United charge at least 12,500 miles for many of these flights.

9,000 miles for flights between JFK & SFO is a steal compared to what other airlines charge.


Avoid Last-Minute Bookings

Pros in the miles and points game will tell you that booking last-minute is a great way to snag award availability. But that’s not a winning approach with SkyMiles.

The dynamic award chart allows Delta to treat its award bookings much like any cash fare. This means that prices can skyrocket in the final weeks prior to departure. Take a look at the next two weeks of fares between MSP and JFK, which generally sell as low as 9,000 SkyMiles one way.

Thrifty Tip #2: When redeeming with SkyMiles, it pays to plan ahead.

Big Savings on Flash Sales

Delta regularly offers occasional sales on award fares – we call them SkyMiles flash sales. Whether it’s a domestic flight that Delta is touting or an unpublished international deal, these sales give you a chance to make your SkyMiles go even farther. They often offer international routes for half the usual amount of SkyMiles Delta charges.

Last spring there were round-trip flights to hotspots in Mexico and Caribbean islands starting at just 12,000 SkyMiles. Those flights generally start at 30,000 miles round trip on both Delta and competing airlines. Neither of those sales were advertised.

Over the summer, Delta put round-trip flights to Asia on sale starting at 30,000 SkyMiles. Considering those flights are typically 70,000 miles to 100,000 miles or more, that’s an absolute steal.

One thing to note is that you’ll need to act fast, as these sales often last just a few days.


Pay With Miles

This extra little feature of Delta’s isn’t always the best strategy, but it can be an absolute steal. Available only to holders of Delta’s American Express cards, Pay With Miles allows you to use each SkyMile as a cent toward a flight in cash. It may not sound like much of a deal, but it can easily save you 10,000 or more SkyMiles if you spot a cheap cash fare here or through your Thrifty Traveler Premium subscription.

One of the best parts of the Pay With Miles feature is that these fares are eligible to earn Medallion Qualifying Miles (MQMs) and Medallion Qualifying Segments (MQSs) towards Delta elite status where standard award tickets are not.

Avoid Partner Airlines … Sometimes

Delta is notorious for devaluing SkyMiles. Their latest price hikes on award flights last year hit SkyTeam partner airlines the hardest. Depending on your destination, booking on a partner airline like Air France or Virgin Atlantic can cost you at least an extra 5,000 SkyMiles in economy and generally another 15,000 or more in business class than the exact same route on a Delta plane.

But that’s not always the case. It can actually be cheaper to book on a partner airline using SkyMiles than board a Delta plane. We’ve explained how Delta award prices can move up and down, seemingly at a moment’s notice. Pricing with partner airlines like Air France, KLM, and China Airlines is far more stable. And that means you may be able to snag a better deal by flying with one of those partner airlines.

Do your research, and you may actually find a better deal flying with Delta’s partner airlines


There are some terrific first class cabins on Delta’s SkyTeam partners flying international routes, including Air France’s La Premiere and Garuda Indonesia. Unfortunately, they’re all off limits when booking with SkyMiles. The SkyMiles program limits you to business class no matter what airline you’re booking as that’s Delta’s highest service on long-haul routes.


Bottom Line

Delta gets a lot of heat for how it handles their SkyMiles program, but with some extra legwork, you can make excellent use of your miles. Unlike most major airlines, SkyMiles never expire. By using this guide, you can be sure you’re spending them wisely.
