The Delta companion certificates you can get from credit cards like the Delta SkyMiles® Platinum American Express Card or the Delta SkyMiles® Reserve American Express Card can easily be worth double the annual fee on both cards … but only if you can find the flights to put them to use. Fortunately, Delta just made that task much easier with one simple – but important – change.

For years, you'd have to search one day at a time to try to. Nothing available for roundtrip flights from New York City (JFK) to Miami (MIA) on Nov. 17 and returning a week later? Start your search over and try again.

But Delta just added a price calendar function when you're searching for flights using a companion ticket, allowing travelers to pull up to a month's worth of flights in one quick glance. It might seem small, but it's a critical improvement: That change can help you zero in on flights that are eligible for this perk, especially when shifting by just a day or two from an initial search.

The strings around using these certificates have made them frustrating for many travelers, as only specific fare classes are eligible. With planes filling up and airlines nearly selling out seats as travel demand surges in 2022, finding a domestic flight that qualifies has felt impossible lately to many Delta flyers who have unused companion tickets from the last two years.

Here's how this new feature works.

 

How to Search with Price Calendar

Rather than starting your search from the Delta.com homepage, you'll want to begin by selecting your Delta companion certificate. And you'll want to do it on desktop – not via the mobile app.

Log in, click your name, and select “My Profile.” If you've got an unused Delta companion certificate, you'll see them under “Certificates, eCredits & Vouchers” along with any outstanding Delta eCredits from canceled flights.

Clicking on the certificate in your profile will allow you to begin the booking and redemption process. Pick the certificate you want to use and then click “Continue.”

From there, just enter the route you're looking for … and remember, these companion certificates are only valid on flights within the continental U.S. – Alaska and Hawaii are off-limits, as are the U.S. territories. Make sure to click “My dates are flexible” before starting your search.

Unfortunately, there are no fares eligible to use a companion ticket on these flights from Minneapolis-St. Paul (MSP) to Denver (DEN) on Sept. 8, returning Sept. 14. Just a week ago, Delta would have merely shown a blank screen with grayed out availability. But here's what you get now.

By allowing travelers to pull up a calendar view, Delta now shows you that leaving just one day earlier or later makes these certificates available to use on these flights to Denver next month. Better yet, it also highlights the cheapest fares available over that initial one-week span.

You can take things even further by selecting “Price Calendar” after you search, pulling up a full month's worth of flights for whatever trip length you set.

These flexible dates and price calendar functions have been around for years, whether you're looking for a cheap flight using cash or trying to redeem some Delta SkyMiles. By looping that in with companion tickets, Delta just made it much easier for flyers to find flights that are eligible to put those certificates to use.

 

Basics on Delta Companion Certificates

These certificates can be gold – but only if you know what you're getting.

You won't get your companion ticket right off the bat when you open a new Platinum or Reserve card account. It starts once you've held either the Delta SkyMiles Platinum American Express Card or the Delta SkyMiles Reserve American Express Card for a full year.

Exactly what you can get depends on which card you've got.

These Delta companion tickets are a use-it-or-lose-it benefit! Pay close attention to the expiration date on your certificate, and be sure to use it beforehand. It's not enough to book before it expires – you have to actually take the trip before it lapses.

You also have to charge the first fare (and the taxes and fees of the second) to an American Express card. It doesn't necessarily need to be the Delta Platinum or Reserve SkyMiles card. However, using a Visa, MasterCard, or any other credit card will not work.

Simple enough, right? But all this doesn't mean that you can buy any roundtrip ticket and use your Delta companion certificate to bring a buddy for free.

You have to find a specific type of fare class in order to apply a Delta companion certificate. That's the reason why many searches when trying to use Delta companion tickets come up empty: Those specific fares just aren't available.

  • With the Delta Platinum Card, you can only book fare classes L, U, T, X, and V in the main cabin.
  • On the Delta Reserve, you can book all those fares plus fare classes I, Z, and W – first class and Comfort Plus tickets.

Other Tips to Put Your Delta Companion Tickets to Use

This change is, pardon the repetition, a game changer for using Delta companion certificates. With one simple tweak, it's much easier to find the flights

But there's still plenty more to keep in mind to make sure you're getting the most out of this benefit.

  • Book early! The closer you get to departure, the harder it's going to get to find flights that qualify for these companion certificates.
  • Use Delta eCredits to pay for your portion of the trip! Sometime in the last several months, Delta added the ability to apply Delta eCredits to the paid ticket even when redeeming a companion fare. Put those canceled trips to use to get even more out of your companion ticket.
  • Pair it with a cheap international flight! One of the best ways to use these certificates is to book positioning flights to get from your hometown airport to a major hub in order to hop on a cheaper fare abroad.
  • Book a trip for two others! If you won't have time to use your companion ticket yourself before it expires, there's nothing stopping you from booking a trip for two (for the price of one!) for friends or family!

Bottom Line

It's a small change with a big impact.

Delta recently added the ability to search for flexible dates when using a companion certificate, making it much, much easier to find flights to book a BOGO trip rather than letting certificates go to waste.
