The American Express Platinum Card provides access to the Global Lounge Collection, which is arguably the most extensive airport lounge program available. This includes the prestigious Centurion Lounges and "Sidecar" by Centurion locations worldwide. Cardholders also get a complimentary Priority Pass Select membership (requires enrollment), which opens up over 1,400 lounges globally. Additionally, you can access Delta Sky Clubs when flying on a same-day Delta-operated flight. Other partners include Escape Lounges (The Centurion Studio Partner), Lufthansa Lounges (when flying Lufthansa Group airlines), Plaza Premium Lounges, and various additional "Global Lounge Collection Partner" lounges. As of 2026, the list continues to expand, though specific guest policies vary; for example, Centurion Lounges now typically charge a fee for guests unless the primary cardholder meets a high annual spending threshold.
