Access to the elite American Express Centurion Lounges is primarily reserved for cardholders of the Platinum Card® (Consumer or Business) and the invite-only Centurion® Card (the "Black Card"). Additionally, holders of the Delta SkyMiles® Reserve American Express Card can access Centurion Lounges, but only when they are flying on a same-day Delta-marketed or Delta-operated flight paid for with an American Express card. As of early 2026, Amex has implemented stricter guest policies: Platinum cardholders must spend at least $75,000 annually on their card to unlock complimentary guest access (up to two guests); otherwise, they must pay a fee of approximately $50 per adult guest. To enter, you must present your valid card, a government-issued ID, and a boarding pass for a departing flight within three hours (or a connecting flight). These lounges are famous for their high-end "buffet" dining, complimentary cocktails, and amenities like shower suites or spa treatments, which are designed to offer a tranquil escape from the crowded main terminals of major airports like JFK, LAX, and London Heathrow.
