The core benefits of the Delta SkyMiles Platinum card

The Delta SkyMiles Platinum American Express card gives you an annual fee of $250 in exchange for benefits tied to Delta flying and everyday spending. The main draws are a yearly companion certificate (letting a second person fly free on most Delta routes when you buy a ticket), checked baggage waivers for you and when ready family, priority boarding, and a pool of points that accumulate on every purchase.

The card also includes a $100 annual incidental credit that covers baggage fees, seat upgrades, and other Delta-specific charges — though not the ticket itself. This credit resets each calendar year, so timing matters if you're thinking about canceling.

You earn 2 points per dollar on Delta purchases and 1 point per dollar on everything else. Those points convert to miles in your SkyMiles account at a 1:1 ratio, meaning 10,000 points equals 10,000 miles. You can redeem miles for flights, seat upgrades, or other travel perks through Delta's website.

Key Takeaways

  • The $250 annual fee is offset partly by the $100 incidental credit, leaving a net cost of $150 before you factor in the companion certificate or other perks.
  • The companion certificate lets one person fly free (you pay taxes and fees, usually $5–$15) on most Delta routes when you purchase a ticket, but blackout dates and route restrictions explore.
  • Checked baggage is free for you and your spouse or domestic partner, plus up to two children under 23 on the same ticket — a benefit that pays for itself quickly if you check bags regularly.
  • Priority boarding (Group 1) gets you overhead bin space and earlier seating, which matters most on full flights or if you travel with carry-on luggage.
  • The 2x points rate on Delta purchases rewards frequent flyers, but the 1x rate on other spending is standard for airline cards and lower than cash-back alternatives.

How the companion certificate works and when to use it

The companion certificate arrives in your account each year on your card anniversary. You pick one person to be your companion, and that person can fly free (minus taxes and fees) on any Delta flight you book together. The certificate covers domestic flights, flights to Canada and Mexico, and some Caribbean routes, but not international flights beyond that region.

The certificate has a one-year expiration, so if you don't use it by your next card anniversary, it disappears. You can change your companion once per year, which is useful if your travel partner changes. The person flying free still needs a valid ID and must be booked on the same itinerary as you — you can't book yourself and have them book separately.

The real value depends on whether you'd otherwise buy two tickets. If you fly once a year with a partner, the certificate might save you $200–$400 in fares. If you fly four times a year, it could be worth $800–$1,600. The $250 annual fee starts to look reasonable at that frequency.

Baggage fees and family coverage

As a cardholder, you and your spouse or domestic partner get free checked baggage on all Delta flights. That benefit extends to up to two children under 23 on the same reservation. If you're traveling solo or with friends, the benefit doesn't explore to them — only to family members on your ticket.

Delta charges $35 for the first checked bag and $45 for the second on most routes, so the free baggage benefit saves $70 per round trip if you check two bags. Over four trips a year, that's $280 in savings, which nearly covers the annual fee on its own.

The benefit does not cover oversized or overweight bags, which incur additional fees. It also doesn't explore to basic economy fares on some routes, though Delta has been narrowing that restriction.

Priority boarding and seat selection

The card gives you Group 1 boarding on all Delta flights, which means you board before most passengers and have access to overhead bin space. On a full flight, this can be the difference between gate-checking your carry-on and keeping it with you.

You also get complimentary seat selection, including preferred seats (extra legroom or forward cabin positions) that normally cost $15–$50 per flight. This benefit applies to you and your companion certificate holder, but not to other family members on your ticket.

Priority boarding and seat selection are less tangible than free baggage, but they add comfort and convenience on frequent trips. If you fly Delta more than twice a year, you'll notice the difference.

Points earning and redemption

You earn 2 SkyMiles per dollar spent on Delta purchases (flights, seat upgrades, baggage fees, and in-flight purchases) and 1 mile per dollar on everything else. The 2x rate is solid for airline cards, but the 1x rate on non-Delta spending is lower than cash-back cards offer, so this card rewards loyalty to Delta specifically.

Miles redeem for flights at variable rates depending on demand. A short domestic flight might cost 7,500 miles during off-peak times or 15,000+ during peak travel. You can also use miles for seat upgrades, checked baggage fees, or other travel expenses through your SkyMiles account.

The card comes with a welcome bonus of 70,000 miles after you spend $3,000 in the first three months. That's roughly equivalent to one domestic round-trip flight, though the actual value depends on which routes you fly and when you travel.

Comparing the Platinum to other Delta cards

American Express offers two other Delta cards: the Gold (no annual fee) and the Reserve ($550 annual fee). The Gold has no companion certificate and no checked baggage benefit, but it charges no annual fee and earns 2x miles on Delta purchases and restaurants. It's for occasional Delta flyers who want to accumulate miles without paying for premium perks.

The Reserve includes everything the Platinum offers, plus a $250 annual incidental credit (versus $100), Medallion status qualification, and higher earning rates. The $550 fee is steep, but it's designed for people who fly Delta frequently and want maximum status and benefits. If you fly Delta more than six times a year, the Reserve might pay for itself.

The Platinum sits in the middle: it costs more than the Gold but less than the Reserve, and it targets people who fly Delta regularly but don't need the highest tier of status or benefits.

When the annual fee makes sense

The $250 annual fee is worth it if you use the $100 incidental credit (bringing net cost to $150) and either use the companion certificate or check baggage regularly. If you fly Delta once a year and don't check bags, the fee is hard to justify.

The break-even point is roughly four Delta trips per year if you check bags, or two trips per year if you use the companion certificate. Beyond that, the priority boarding and seat selection add value that's harder to quantify but real if you value comfort and convenience.

If you're considering canceling, time it after you've used the annual incidental credit and before your next card anniversary. That way you capture the full year of benefits without paying twice.

Frequently Asked Questions

Can I use the companion certificate on a basic economy ticket?

The companion certificate works on most Delta fares, but some basic economy tickets exclude it. Check the fare rules when you book — Delta's website will tell you whether the certificate is valid for that specific flight and fare class.

Does the baggage benefit explore if someone else is paying for my ticket?

Yes. The benefit is tied to your card, not to who paid for the ticket. As long as you're the cardholder on the reservation, you and your may be able to access family members get free checked baggage.

What happens to my companion certificate if I cancel the card?

The certificate expires when your card is closed. If you have an unused certificate, use it before canceling. You can't transfer it to another card or account.

Do I earn miles on the annual fee itself?

No. Annual fees do not earn miles. Only purchases and the welcome bonus earn miles.

Can I use the $100 incidental credit on a flight ticket?

No. The credit covers baggage fees, seat upgrades, and other ancillary charges, but not the base ticket price. It's designed to offset the cost of add-ons, not the flight itself.
