Amex Platinum vs Business Platinum: which lounge card fits?

The real difference#

In Lounge Frog's data these two cards are lounge twins. Amex Platinum and Business Platinum each open Priority Pass, Centurion Lounge, Plaza Premium, Escape Lounges, and Delta Sky Club. On both, the Sky Club grant applies only when you are flying Delta the same day.

That means there is no airport where one card gets you into a lounge the other cannot. The comparison is not about footprint at all; it is about which version of the card you are eligible for and which fits how you spend.

Where each card has the edge#

The annual fee is the same on both: $895. With identical fees and identical networks, the personal Platinum is the straightforward pick for someone without a business, and the Business Platinum is the straightforward pick for someone who wants business spending kept on its own account.

Some travelers hold both, which does not expand the lounge map but can matter for household logistics, since each card can carry its own guest policy and its own enrollment in networks like Priority Pass. If you are choosing only one, eligibility and bookkeeping decide it; the lounge access itself is a wash.

How I'd make the choice#

Even when the networks match, it is worth listing your next three airports and checking whether Centurion, Escape, Plaza Premium or Priority Pass lounges are actually present and airside in your terminal. Confirm enrollment steps, the same-day boarding-pass requirement at Sky Club, any visit limits, and guest charges, since those govern day-to-day use more than the brand list does. Terms can change on either product, so verify current details with American Express before applying. See our methodology for how grants are recorded.

Putting this into practice#

I would start this comparison with the next few trips already likely to happen. For each card, I'd list the lounges that fit those airports and departure areas, then remove locations that would require an impractical detour. That is a more useful comparison than adding up every lounge in a worldwide network, most of which may never help with those trips.

Guest rules deserve their own line in the calculation. A card that works well for one person can be a different proposition for a couple or family. I'd compare the cost for the party that actually travels, including any separate membership or additional-card charge. I would not assume a benefit on one version of a card applies to another version.

The annual fee is only part of the decision. I would value other benefits at the amount I would realistically use, rather than automatically count a credit at face value. A benefit that requires a booking I would not otherwise make does not reduce my costs in the same way as money saved on an existing plan.

The trade-offs I would check#

I would check enrollment and the credential needed at reception before relying on either card. Some benefits are used through a separate membership rather than by showing the payment card. The issuer's current terms should settle the visit allowance, guest treatment and any airline or fare restriction. The comparison above helps identify the differences worth checking.
