|---|---|---|
| Lounge access | None | Yes — United Club |
| Annual credits | None | None |
| Points & redemptions | Locked to a single program | Locked to a single program |
On perks and redemptions, only the United℠ Business Card gets you into airport lounges. Weigh those against the fee, since credits and lounge access only count if you will actually use them.
Transfer partners and point value
Neither card earns transferable points, so redemptions are cash-back or fixed portal value on both, roughly a cent per point. There is no airline or hotel transfer angle to separate them.
The verdict
On a typical year of business spending, the Delta SkyMiles® Platinum Business earns about $546 a year in rewards and the United℠ Business Card about $570, valuing every point at a flat 1 cent. The Delta SkyMiles® Platinum Business charges $195, which you clear through its rewards and perks. The United℠ Business Card charges $150, which you clear through its rewards and perks. Counting rewards, fees, and any credits, the United℠ Business Card delivers more total value, about $69 a year more for a typical spender, mostly because it earns more where you spend most, on office supplies. Neither leans on transferable points, so the deciding factors are the welcome offer, the card network, and which everyday perks you will actually use. On the sign-up bonus, the two are currently comparable in size. Note that Delta SkyMiles® Platinum Business is running a limited-time offer above the usual amount, so that edge may not last. A welcome bonus is a one-time event, so weigh it apart from the ongoing rewards.
Pick the Delta SkyMiles® Platinum Business if your spending leans toward travel. Pick the United℠ Business Card if your spending leans toward office supplies.
