No, the American Express Platinum Card does not provide complimentary access to the United Club in 2026. This is a common point of confusion for travelers. While the Amex Platinum offers the "Global Lounge Collection," which includes access to The Centurion Lounges, Delta Sky Clubs (when flying Delta), and Priority Pass lounges, it does not have a partnership with United Airlines. To access the United Club, you would typically need a United Club Infinite Card, a separate United Club membership, or to be traveling in a premium cabin on an international flight. For 2026 cardholders, the best alternative at airports like Newark or Houston is to utilize the Centurion Lounge or an Escape Lounge, both of which are accessible with your Platinum card regardless of which airline you are flying that day.
