Delta Companion Certificate: 2026 Rules and How to Use It

Which cards include it

The certificate comes with 4 American Express cards: the Delta SkyMiles Platinum, Reserve, Platinum Business and Reserve Business. The Gold and Blue cards do not include it. You receive 1 certificate each year in your renewal month, after you pay the annual fee, so there is none in the first membership year (American Express Delta FAQ, checked October 22, 2026). Confirm the current fees at Amex, since the certificate’s value is measured against them.

How the certificate works

The certificate covers one round-trip companion ticket. You book yourself on a qualifying paid fare and add the companion on the same reservation. The companion pays only government-imposed taxes and fees, from about $22 on a domestic nonstop, capped at $80 for a domestic round trip and $250 for an international one, for itineraries of up to 4 flight segments. Both travelers must be on the same flights, the same dates, the same cabin, and the same record, booked at the same time.

Platinum vs Reserve: the cabin difference

This is the main reason to hold the Reserve over the Platinum.

The Reserve certificate is far more useful because a First Class or Delta Comfort companion seat is worth much more than a Main Cabin one, and premium seats are often easier to find at the required fare classes on the routes people actually book.

Where you can fly

The certificate is valid for round trips that start in the U.S., Puerto Rico, or the U.S. Virgin Islands, to destinations across the U.S. and much of the Caribbean, Mexico, and Central America, including the Bahamas, Jamaica, the Dominican Republic, Turks and Caicos, Aruba, Costa Rica, Belize, Panama, and more. It is not valid for travel that originates outside those regions.

How to actually book it

The certificate is easy to earn and easy to waste, because most fares on a given route are not in the eligible fare classes. The trick is to check fare-class availability before you commit.

1. Log in to Delta.com or the Fly Delta app. The certificate sits in your profile under Certificates, eCredits & Vouchers; select it there before you search.
2. Search your round trip and look for the “companion certificate” fare option at checkout. If it does not appear, the flights are not in an eligible class.
3. To scout in advance, use ITA Matrix and add the fare-class extension codes for your card (for example L, U, T, X, V for the Platinum) so you only see flights the certificate can book.
4. Add your companion to the same reservation, in the same cabin and flights, and pay the taxes and fees.

In ITA Matrix, put the fare-class filter in the extension codes box so only companion-eligible fares appear. For a Platinum card, whose Main Cabin classes are L, U, T, X, and V, use this string: f bc=l|bc=u|bc=t|bc=x|bc=v. Both the outbound and the return must price in one of those classes, and both travelers must sit on the same itinerary, booked together.

On the Reserve card, the certificate also books Delta Comfort, First, and Premium Select, so widen the filter to the Reserve fare classes. Per Delta’s certificate terms, checked October 5, 2026, those add W and S for Delta Comfort (S only when L, U, T, X or V is open in Main), A and G for Delta Premium Select, and I and Z for First, giving an extension code like f bc=l|bc=u|bc=t|bc=x|bc=v|bc=w|bc=s|bc=a|bc=g|bc=i|bc=z. Confirm your card current eligible classes with Delta, since the letters can change.

Reading the results: ITA Matrix shows the booking class in each fare detail. If your dates only return classes outside your list, try nearby days or a different Delta hub, because the eligible buckets open and close with demand. Once you find eligible flights, book the exact same segments on Delta.com and add your companion in the same cabin.

Taxes, fees, and the real cost

The companion pays government taxes and fees: about $22 on a domestic nonstop round trip, capped at $80 domestic and $250 international (Delta, checked October 22, 2026). Even so, on a $400-plus fare the certificate routinely saves several hundred dollars, which is how it helps offset the card’s annual fee.

Restrictions and gotchas

The certificate is valid for one year from the date it is issued, and all travel must be booked and fully flown by that expiration. Both passengers must travel together on the same itinerary. Delta One is never eligible, even on the Reserve. Fare-class availability is the real limiter, so book early and stay flexible on dates.

A worked example: what 1 certificate saves

Say a Main Cabin round trip in an eligible class prices at $450 per person. 2 paid tickets cost $900. With the certificate you pay $450 for your ticket and about $22 in taxes for the companion, $472 in total, a saving of $428. That covers the $350 Platinum fee with $78 left over, from 1 trip. The same math on a $250 fare saves $228, which no longer covers the fee by itself. The companion certificate calculator runs your own fare, taxes and fee.

Is it worth the annual fee

For someone who takes at least one trip a year with a companion, a single good use of the Reserve certificate can return more than the $650 fee on its own, before lounge access and other benefits. The Platinum certificate is worth less because it is Main Cabin only, so weigh it against the lower fee. See the Delta SkyMiles Reserve or Platinum card guide to choose between them.

Platinum or Reserve: the $300 question

The Reserve costs $300 more than the Platinum. The certificate is where that money shows up most clearly, because a First Class companion seat on a transcontinental route is worth several times a Main Cabin one.

Run it against your own travel. If you fly 2 people to a domestic destination once a year in economy, the Platinum certificate covers it, and the extra $300 buys lounge access and a higher earn rate you may not use. If you would book First or Premium Select for 2, the Reserve certificate can return the fee difference in a single trip.

Watch for 1 trap: buying the Reserve for the certificate and then only finding Main Cabin fares in eligible classes. Premium cabin classes open less often, so the wider certificate takes more searching to use. Hold the Reserve when you have a specific route where you would book First and you want the lounge access too. Read the fee math on the Reserve guide and the Platinum guide before you decide.

Confirm current terms at Delta or American Express.

Is the Delta Reserve worth $300 more than the Platinum for the certificate?

Only if you will book Delta Comfort, Premium Select or First for 2. In Main Cabin the 2 certificates work the same way, so the extra fee buys lounge access more than certificate value.

Can you use the Delta companion certificate to Hawaii?

Yes. Delta counts Hawaii as travel within the United States, so the companion pays taxes and fees capped at $80 for the round trip, provided the fare books in an eligible class.

Does the companion earn miles on a companion certificate ticket?

No. Delta’s terms say the companion ticket earns no miles and no MQDs. Your own paid ticket earns as normal.
