|---|---|---|
| Lounge access | Yes — Centurion, Priority Pass, Delta Sky Club | None |
| Annual credits | ~$3,064/yr (12 credits) | None |
| Points & redemptions | Transferable to airline & hotel partners | Locked to a single program |
On perks and redemptions, only the American Express® Platinum gets you into airport lounges; the American Express® Platinum carries the heavier credit stack (about $3,064 a year); the American Express® Platinum earns transferable points with a higher redemption ceiling, while the other is capped nearer a flat cent. Weigh those against the fee, since credits and lounge access only count if you will actually use them.
Transfer partners and point value
Only the American Express® Platinum earns transferable points. Its Amex Membership Rewards move to Delta, ANA, Air France-KLM Flying Blue, Virgin Atlantic, plus Hilton and Marriott, where a point can be worth several cents on a premium-cabin redemption, far above its cash value. The Marriott Bonvoy Boundless® stays locked to a single airline or hotel program, so its ceiling is nearer a penny per point no matter how you redeem.
The verdict
On a typical year of household spending, the American Express® Platinum earns about $364 a year in rewards and the Marriott Bonvoy Boundless® about $671, valuing every point at a flat 1 cent. The American Express® Platinum charges $895, but carries about $3,064 in annual statement credits that offset it for anyone who uses them. The Marriott Bonvoy Boundless® charges $95, which you clear through its rewards and perks. Counting rewards, fees, and any credits, the American Express® Platinum delivers more total value, about $425 a year more for a typical spender, mostly because it earns more where you spend most, on travel. The bigger difference is the ceiling: the American Express® Platinum earns points you can move to travel partners for outsized value, while the Marriott Bonvoy Boundless® stays locked to a single airline or hotel program. Favor the American Express® Platinum if you will use travel transfers, the Marriott Bonvoy Boundless® if you want simplicity. On the sign-up bonus, the two are currently comparable in size. Note that American Express® Platinum and Marriott Bonvoy Boundless® are 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 American Express® Platinum if your spending leans toward travel. Pick the Marriott Bonvoy Boundless® if your spending leans toward dining, groceries, gas.
