What's changing
Starting July 8, 2026, American Express is tightening Platinum Card access to its Centurion Lounges:
- Connecting passengers are now limited to a 5-hour pre-departure window before their next flight — previously, cardholders could enter with no such restriction and stay for however long their connection allowed.
- Guests must now be booked on the same flight as the cardholder. Previously, a cardholder could bring guests who weren't traveling on the same itinerary at all; that loophole is closed.
What isn't changing
This is an access-policy change, not a benefits or pricing change — the Platinum's $895 annual fee, its earn rates, and every one of its statement credits (Uber Cash, Digital Entertainment, Airline Incidental, Hotel, and the rest) are unaffected. If you're not a frequent Centurion Lounge user, nothing here changes your math.
Who this actually affects
Mainly long-layover connecting passengers who used to treat Centurion Lounges as an extended-stay option, and cardholders who brought along guests meeting them at the airport rather than flying with them. If neither describes your travel pattern, this change is close to invisible.
Does this change whether the Platinum is worth it?
Lounge access was never the primary earn-rate driver in our Platinum comparisons — the card's case rests on its 5x travel earn rate and its credit stack, which are untouched here. But if Centurion Lounge access for long connections *was* a deciding factor in your setup, it's worth re-checking whether the card still clears your bar before your next trip. Run the optimizer to see how the Platinum stacks up against alternatives for your actual spending, independent of lounge perks.
