Struggling to Use Your Delta Companion Certificate? Read This Guide

If you're a frequent Delta flyer, odds are you've got a co-branded Delta credit card in your wallet. And while the Delta SkyMiles® Gold American Express Card is the most popular choice, two cards with higher fees are worth considering for one big reason: An annual Delta companion certificate.
While SkyMiles may not go far these days , these Delta companion certificates can be reason enough to keep a top Delta card in your wallet. Think of them as a buy-one, get-one benefit for flights each year: Use them wisely, and you can get plenty of value, often outweighing whatever annual fee you're paying on your Delta card.
But for many flyers with these certificates in their wallets, it's gotten harder to put them to use over the last year or two, running searches that turn up blank when trying to apply a companion certificate. We're here to help. And luckily, Delta has made it a bit easier by introducing a new price calendar feature when searching for flights using your Delta companion certificate.
Whether you've already got a Delta companion ticket in your account or you're eyeing the latest Delta credit card offers , we'll give you some hints on how to make sure you use them wisely.

 
What is a Delta Companion Certificate?
What's a Delta companion certificate? Well, it's one of the best benefits of any Delta credit card.
The Delta SkyMiles® Platinum American Express Card gets you an annual companion certificate to use on economy fares within the continental U.S. That means Hawaii and Alaska are off-limits.
The Delta SkyMiles® Reserve American Express Card comes with a companion certificate that also works for Delta Comfort Plus and first class tickets within the continental U.S.
You'll get this perk after your first full year with either of the two top-of-the-line Delta credit cards. That means you'll need to wait a year after opening one of these cards – then renew it again – to get a companion ticket.
 
How Does the Delta Companion Certificate Work?
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. Again, let's go over some basics:

The Delta SkyMiles® Platinum American Express Card ‘s companion certificate is good for one main cabin roundtrip fare in the continental U.S.
The Delta SkyMiles® Reserve American Express Card ‘s companion ticket can also be used for Comfort Plus and domestic first-class airfare.

And remember: 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 before then. It's not enough to book before it lapses – you have to actually take the trip before it expires.
 
 
The paid fare will earn SkyMiles and Delta Medallion Status credits, but the free fare will not . If you've got Delta status, both of you will be eligible for complimentary upgrades . Unfortunately, you cannot use SkyMiles to book the first ticket: Paid fares only.
One final important restriction to keep in mind: You 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…
 
Which Fares Qualify?
While it can still be an incredible benefit, there are some serious strings attached to these Delta companion tickets that can make the right fares harder to find and book. You have to find a specific type of fare class in order to apply a Delta companion certificate.
While you may only see first class, Comfort Plus, and economy seats when you walk on a Delta plane, airlines sell an alphabet's worth of different ticket types called fare classes – each with its own rules, restrictions, and price. And only a handful of the two-dozen-plus fares are eligible to use these Delta companion certificates:

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 Card, you can book all those fares plus fare classes I, Z, and W – first class and Comfort Plus tickets.

 
Look for the fare class to make sure your ticket qualifies for a free companion.

Depending on where you live and when you're flying, these restrictions can make it more difficult to get a lot out of the companion pass. Delta Basic Economy fares are off-limits, and many of the fares that do qualify are often some of Delta's cheaper tickets.
And that's the problem many Delta flyers with these companion certificates are running into now. With airfare on the rise lately , Delta isn't selling nearly as many of these fare classes that make the cut. That's why many travelers are searching for flights to use their companion tickets and coming up empty.
But don't worry. We've got plenty of tips to help you find a way to make it work. Keep reading…
 
How to Use a Delta Companion Pass
Once you've earned a companion certificate, you'll get an email from American Express informing you that the certificate is now available. Log in at Delta.com , and you'll find it's been automatically placed in your Delta profile wallet under “Certificates, eCredits & Vouchers.”
 
 
Clicking on the certificate in your profile will allow you to begin the booking and redemption process. Unlike the Southwest Companion Pass , there is no need to designate your travel companion ahead of time: You can bring anyone with you.
Once you've found it, make sure your companion certificate applies, and voila – a nearly free plane ticket! You'll pay just the government-imposed taxes and fees in addition to the price of the first fare. The final amount will vary based on your destination.
 
 
That said, there are a few other quirks to keep in mind…
 
Can You Use a Delta Companion Certificate Booking with SkyMiles?
No. Sadly.
Delta does not allow travelers to use a stash of Delta SkyMiles to book the first ticket when applying a Delta companion certificate. It has to be a paid fare, and you have to pay with an American Express card.
 
But Can You Use Delta eCredits, Too?
Yes!
This is one of the best developments we've seen recently. Sometime last year, Delta added the ability to apply Delta eCredits to the paid ticket even when redeeming a companion fare.
After years of canceling flights through the pandemic and many extensions to make these eCredits last through 2024, we know plenty of Delta flyers still have credits sitting around in their accounts. Using a companion certificate and eCredits together can help make your flights even cheaper – it's the ultimate two birds, one stone.
To do so, just select your companion certificate as normal, then begin your search and select your flights. Once you make it to the checkout screen, select “Use eCredits” and Delta will allow you to pull in credits to offset the cost of your paid fare.
 
 
Delta allows you to apply up to four eCredits online during these transactions, though you might be able to use even more at once by calling Delta to book your tickets instead.
So long as there's a balance left over – and because you're paying your companion's taxes and fees, there will be – just finish up by paying with an Amex card and you're set!
 
Can Someone Else Use a Companion Certificate?
Yes … usually.
Nearly all Delta companion certificates that come through Delta's SkyMiles credit cards are  fully transferrable. So while a cardholder may always prefer to use the perk that they're paying for, that's not always possible. Fortunately, there's no requirement on these certificates that the cardholder booking the flights actually takes the trip. For instance, you could book a flight for your spouse and child using the companion certificate for one of the fares, so long as you pay for the flights with your Delta Amex card.
 
Tips to Use & Maximize Your Delta Companion Ticket
What's the best way to use a Delta companion ticket? We're glad you asked.
In theory, these Delta companion certificates are worth their weight in gold. It's a BOGO ticket and an easy way to offset the annual fee on your top-dollar Delta Amex card.
But in practice, redeeming these certificates has become a chore over the last few years. We've heard from countless frustrated travelers who have tried and tried and tried to find flights to use this perk only to come up empty-handed every time.
You're not alone. Here's some advice on how to find the fares that work, then squeeze all the juice out of your Delta companion ticket when you can.
 
A Next-Level Tip to Find the Right Fares
How on earth can you find those special L, U, T, X, and V fares you need to use these certificates? Are you supposed to just search route after route on Delta until you finally come up with a result?
There's a tool that can easily help you zero in on flights that work: It's called ITA Matrix. I'll show you exactly how it can help in this situation.
 
 
Think of ITA Matrix like Google Flights on steroids … and then some. While it's a fairly advanced platform, it has a ton of powerful features that you won't find on Google Flights or other sites. Most importantly, it allows you to search for specific fare classes … including the ones you need in order to find flights to use your Delta companion certificate.
Let's say I'm trying to use my companion certificate for a few nights in New York City toward the end of summer, but all my searches through Delta are coming up blank. Using some of ITA Matrix's advanced controls, I can tell it to show me exactly when the eligible flights are available.
First, head to ITA Matrix and plug in the basics of your trip. It helps immensely if you're flexible, so I'd recommend selecting “See calendar of lowest fares” rather than inputting exact dates.
 
 
Now it's time to tell ITA Matrix we only want to see flights that can be booked with a Delta companion ticket. ITA Matrix allows you to search only for specific fare classes. Just click “Advanced controls,” and then copy and paste the following bits of code in the outbound and return extension code fields.

Platinum cardholders booking economy fares, enter f bc=L|bc=U|bc=T|bc=X|bc=V
Got the Reserve Card and want to make sure you're flying first or Delta Comfort Plus? Enter f bc=I|bc=Z|bc=W

In this case, I'm searching only for the main cabin economy fares that can be booked with a Platinum Card companion certificate by telling ITA Matrix to only show fares with the booking codes L, U, T, X, or V.
 
 
It may take a minute or so, but eventually, ITA Matrix will pull up a calendar with results. Click airlines and narrow down your results to only show Delta flights.
 
 
At $400 or even north of $500 per person, Delta flights aren't cheap over this span – but getting two tickets for the price of one takes the sting out of those fares. Flights departing Tuesday, Aug. 15, and returning Saturday, Aug 19 are in fare class T, which does the trick to use a Delta companion certificate.
 
 
So from there, I head over to my Delta account, select my companion certificate, enter those dates, and hit search. Sure enough, it did the trick!
 
 
While you'll still need to be flexible, there's perhaps no better way to cut through the painstaking trial-and-error process of trying to find flights to use your Delta companion ticket than this.
 
Select ‘My Dates are Flexible'
For many years, you'd have to search one day at a time to try to find flights that work with your companion certificate. Nothing available for roundtrip flights from New York City (JFK) to Miami (MIA) on Aug. 17 and returning 10 days later? Start your search over and try again. It was exhausting.
But one small change last year has made it much, much easier: Delta now offers 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. 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.
Just start the search process by going into your Delta profile and selecting the companion certificate you want to use. As you enter your travel dates, be sure to select the “My dates are flexible” box when starting your search with your Delta companion certificate.
 
 
Previously, if you chose dates that weren't eligible to use a Delta companion certificate, your search would show up blank. Here's what you get now instead.
 
 
By allowing travelers to pull up a calendar view, Delta now shows you that returning just a day or two earlier makes these certificates available to use on these flights to Miami this summer. 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.
Using ITA Matrix is still more powerful, but this makes it much easier to put those certificates to use without leaving Delta.com .

Be Flexible & Plan Ahead
The closer you get to departure, the harder it's going to get to find flights that qualify for these companion certificates.
If you're searching for a flight just a month or less in advance, your odds of finding flights that work are fairly slim. That's especially true now, as sky-high travel demand and higher airfare have made it all but impossible to find the fare classes that are eligible.
We can't tell you exactly how far in advance you need to search to break through: It's unpredictable. But you'll definitely have better odds of making it work by searching at least three to six months out.
Just remember: You have to book and take the trip before your companion certificate expires.  If your return date falls beyond the expiration window, it won't work.
 
Book the Most Expensive Ticket You Can!
Start thinking big to make the most out of your Delta companion ticket.
Any round-trip, main cabin (or first class, if you have the Delta Reserve Card) flight within the lower 48 U.S. states will qualify – as long as it falls into one of the fare classes above. And some will be better options than others to maximize the value of your certificate.
Cross-country routes and even some short-haul flights consistently tend to be the most expensive. But airfare dips and skyrockets so wildly, that can be hard to predict.
Here's the bottom line: Make sure you book a flight that costs $250 (see rates & fees ) or more per ticket if you hold the Delta Platinum Card, or $550 or more (see rates & fees ) if you hold the Delta Reserve. That's the key to making the annual fee on either the Platinum or Reserve Delta SkyMiles card worth it. Regardless of any other benefits the cards provide, this one can cover the entire cost of your annual fee.
We've regularly been able to get $300 or far more in value out of the companion certificate. And that's before factoring in the value of free checked bags for everyone on the itinerary! You can use the benefit for any travel in the continental U.S. so there are endless redemption options that will maximize the value of the ticket.
 
Pair it with an International Fare Deal
Consider using your Delta companion ticket to lower the costs of an international getaway.
Earlier this year, we sent our Thrifty Traveler Premium members a jaw-dropping deal on flights to Tahiti (PPT): Just $498 roundtrip! That's a fantastic deal, less than half the normal price of flights to paradise.
 
 
But those cheap nonstop fares were only available from Los Angels (LAX). If that's not your home airport, the cost of getting there to make the trek to Tahiti could make the deal look less attractive. Enter the Delta companion certificate.
Using your Delta companion ticket to book positioning flights is a smart move. It means you can book that cheap international ticket from a different city, then use your companion certificate to fly from your hometown to catch that international flight for less.
 
All About the Delta SkyMiles Platinum Card
The Platinum Delta SkyMiles card by American Express is one of several options for Delta cards, but it's among our favorites. That's due in large part to this companion certificate, which can easily net you $300 or more in value every single year. You'll get the benefit after your first full year with the card. But there are other perks to the card, too.
The Platinum Delta SkyMiles card will also get you free checked baggage for anyone on your itinerary. And you'll never pay pesky foreign transaction fees.
The card earns 3x SkyMiles per dollar spent at both hotels and on Delta purchases. It also earns 2x SkyMiles per dollar spent at both restaurants and U.S. supermarkets. You'll also get a $100 credit for either  Global Entry or TSA PreCheck once every four years. Membership in both programs is good for five years.
Long layover on your international journey? The Platinum Delta SkyMiles card can get you into the Delta SkyClub for $50 per person. If you don’t already have a card that includes lounge access , this is a great way to access the Delta Sky Club.
While we feel Delta SkyMiles have lost their luster recently, some bonus miles just sweeten the deal. You can currently bonus_miles_full
The card does have an annual fee of $250 (see rates & fees ), but it can easily be offset with the companion ticket it provides.

All About the Delta SkyMiles Reserve Card
The Delta SkyMiles Reserve card by American Express is the top-tier card in the Delta co-branded credit card portfolio.
That's due in large part to this companion certificate. Unlike the companion certificate from the Platinum card, it can be used for both Comfort Plus and domestic first-class tickets, too. You'll get the benefit after your first full year with the card.
The card earns 3x SkyMiles per dollar spent on Delta purchases. You'll also get a $100 credit for either  Global Entry or TSA PreCheck once every four years. Membership in both programs is good for five years.
Long layover on your international journey? The Delta SkyMiles Reserve card gets you complimentary access to the Delta Sky Club. You'll also be able to access Amex's incredible Centurion Lounges and Escape Lounges so long as you book your Delta flight with the Reserve card.
There's also a welcome bonus: You can now  bonus_miles_full
With an annual fee of $550 (see rates & fees ), it certainly isn't for everybody.
