Delta's mid-tier personal credit card is quietly one of the better airline cards for people who fly the airline a handful of times a year. The Delta SkyMiles Platinum American Express carries a $350 annual fee, but between a yearly companion certificate, free checked bags, and a path to elite status through spending, it can pay for itself fast — if you actually use Delta.
The headline perk is the annual companion certificate. Each year after renewal, you get a second passenger on a roundtrip Delta Main fare within the US (including Alaska and Hawaii) or to select Caribbean and Central American destinations, paying only government taxes and fees of roughly $22 to $250 for the second traveller. One redemption can easily exceed the annual fee. You also get a first checked bag free on Delta flights worldwide (second bag free on domestic routes), Zone 5 priority boarding, and 15% off Delta award bookings — a meaningful discount, since SkyMiles redemptions are priced dynamically.
On the earning side, the card pulls 3x miles on Delta purchases and direct hotel bookings, 2x at restaurants worldwide and US supermarkets, and 1x elsewhere. New applicants can score a welcome offer of up to 90,000 bonus miles after spending $3,000 in the first six months — worth roughly $990 at a conservative 1.1-cents-per-mile valuation. Note it's a once-per-lifetime bonus, and you're blocked if you've held the personal Reserve card, so apply for lower-tier Delta cards before upgrading if you want to collect multiple bonuses over time.
Status chasers get a $2,500 head start on Medallion Qualification Dollars each year, plus $1 MQD per $20 spent. That's a slow route to Gold (which needs $10,000 MQDs) — the pricier Reserve card earns MQDs twice as fast — but for Silver ($5,000 MQDs) it's realistic. The card also stacks up to $390 in annual statement credits: $120 rideshare, $120 at Resy restaurants (both $10 monthly, enrolment required), and $150 on Delta Stays hotel bookings, plus a Global Entry or TSA PreCheck fee credit every four years. No foreign transaction fees, and free authorised users round it out.
The main catch: no Delta Sky Club lounge access — that's reserved for the Reserve tier — and the rewards rates, while decent for a co-brand card, are beaten by general travel cards. Best value goes to frequent Delta flyers who'll redeem the companion certificate and can absorb the fee. If you're Delta-loyal and book at least one paid domestic roundtrip a year, the maths works; otherwise, a flexible rewards card probably serves you better.
