Not all companion certificates are created equal, though. Earning some requires considerable credit card spending, and others only reduce ticket costs to $99 rather than $0. Thankfully, a Delta companion certificate involves neither of those stipulations, making it much easier for travelers to use and enjoy.

Here's what you need to know about how to earn and redeem a Delta companion certificate — and then how to maximize it.

How To Earn a Delta Companion Certificate

The easiest thing about Delta's companion certificate is earning it. All you need to do is hold an eligible Delta credit card for a year. Then, on your cardmember anniversary, Delta will issue you a companion certificate — and on each anniversary after that. The following Delta credit cards offer companion certificates:

The companion certificates from these cards have differences, however. Platinum-tier cards receive a companion certificate on Main Cabin domestic, Caribbean, or Central American round-trip flights to select destinations each year. Note that domestic now includes Hawaii and Alaska for non-residents, too.

Reserve-tier card members can book round-trip travel to the same destinations in any cabin. However, the Reserve cards also charge a higher annual fee.

How To Locate Your Companion Certificates

Delta companion certificates are easy to earn and easily accessible — both online and in the airline's mobile app. To access companion certificates through Delta.com, log into your SkyMiles account and navigate to “My Profile.” From there, along the left-hand side of the screen, select “Certificates, eCredits & Vouchers.”

An alternative way to get to a similar landing point is to first log in. Then, you can hover over “SkyMiles” at the top of the screen and select “Certificates & eCredits” at the bottom left of the drop-down menu.

How To Use a Delta Companion Certificate

To book flights using a Delta companion certificate, check the box of the certificate you want to use and select “continue.”  Conveniently, Delta displays expiry dates for each individual companion certificate, so members can specifically choose to use the certificate expiring soonest.

If you click the red drop-down arrow on the right-hand side, you'll see additional information about the companion certificate. Here, you can find the issue date, certificate number, and reference code. Most importantly, you'll also see eligible booking classes.

For certificates earned from a Platinum Delta Amex or Delta Business Platinum Amex, eligible fare classes include L, U, T, X, and V.

Certificates earned with a Delta Reserve or Business Delta Reserve enjoy additional eligible fare classes of I and Z for first class and W or S fares in Comfort+, provided the L, U, T, X, and V fares are available in Main Cabin.

How To Maximize a Delta Companion Certificate

Once you select a Delta companion certificate, you can search for and book a flight. The search process operates quite similarly to a normal flight search, complete with flexible date and price calendar options. These search options will help you to identify fare class availability and the greatest savings.

For example, companion certificates now work for flights to and from Hawaii. Delta happens to fly the longest scheduled domestic routing in the U.S. between Boston and Honolulu. The 5,095-mile flight doesn't come cheap, and if that travel is over a holiday weekend, the price climbs even more.

Thankfully, a companion certificate virtually halves the cost for two travelers. For a sample one-week trip between Boston (BOS) and Honolulu (HNL) spanning Martin Luther King Jr. Day weekend in January, Delta's direct flight offers the quickest possible trip:

Fortunately, there are eligible fare classes for using a companion certificate on these exact flights. As a result, would-be travelers save over $800!

Example of using a Delta companion certificate to cut costs on a trip between BOS and HNL.

Why are savings not exactly half of the cash price? This is because companion tickets require the payment of taxes and fees of between $22 and $250 (for itineraries with up to four flight segments). Applying the companion certificate eliminates the base fare and the $32 per passenger U.S. Transportation Tax.

Final Thoughts

When used optimally, the Delta companion certificate more than covers the card's annual fee. Thankfully, Delta makes these certificates easy to access and easy to redeem. Additionally, flexible flight search functionality lets certificate holders identify and book the flights that work best for them. Also, it can help them realize the most value.

Anyone who travels on Delta with at least one other companion stands to gain from these companion certificates. This includes those who live outside the United States but travel to the U.S. mainland at least once a year. Provided the fare class availability exists, Delta companion certificates unlock quality value for SkyMiles members. Plus, you're still eligible for complimentary upgrades if you have Delta Medallion elite status.
