Yes, access to the Plaza Premium Lounge network is a complimentary benefit for holders of the American Express Platinum Card and the American Express Business Platinum Card. In 2026, these cardholders can enter any participating Plaza Premium Lounge simply by presenting their valid card, a government-issued ID, and a confirmed boarding pass for same-day travel. Additionally, Platinum cardholders are usually permitted to bring two guests into the lounge at no extra charge, though this is always subject to space availability. It is important to note that other Amex cards, such as the Gold or Green cards, do not provide this free access; however, some of these cards come with a Priority Pass membership that may include select Plaza Premium locations in its network. For those with a Delta SkyMiles Reserve card, access to Plaza Premium lounges is also included but only when flying on a Delta-marketed or Delta-operated flight. Always check the specific lounge's entry policy via the Amex Global Lounge Collection website to confirm hours and guest limits.
