Yes, you can access the Priority Pass network with several premium American Express cards, but there is a crucial "enrollment" step. Holding an Amex Platinum or Gold Card does not automatically grant you entry at the lounge door; you must first log into your American Express account and formally enroll in the Priority Pass Select program. Once enrolled, you will receive a digital or physical membership card. In 2026, the Amex Platinum card provides unlimited complimentary visits for the cardholder and up to two guests (at most locations), while the Amex Gold Card typically offers a limited number of "passes" per year before a fee is charged. A significant "catch" for Amex-linked Priority Pass memberships in 2026 is that they exclude "non-lounge" experiences like airport restaurant credits or spa treatments, which are sometimes included in Priority Pass memberships issued by other banks like Chase or Capital One. Always check the Priority Pass app before your flight to confirm which specific lounges in your terminal accept the card.
