Delta SkyMiles Gold Business vs Delta SkyMiles Platinum Business

Every figure below is from the same dataset Miles computes its recommendations from. Rows the two cards agree on are collapsed at the bottom.

Economics

Dollar figures are per year unless the row says otherwise. Ongoing annual value is Miles' estimate of what the card adds per year after its annual fee: statement credits discounted for realistic use, benefits, and earning above a strong flat-rate card on a typical spending profile. First-year value is a separate net figure that includes the welcome bonus. A welcome bonus shown at its advertised maximum may not be available to every applicant; that figure is not marked as stronger. ★ marks the stronger comparable figure on other rows, and no row is marked when either figure is unknown.

Sign-up Bonus

Which one is right for you

This page shows the difference. It does not pick: the winner depends on what you spend and what you already hold, and adding these figures up without knowing that would be a guess dressed as a verdict. Ask Miles and it computes the answer against your own wallet.
