Yes, the American Express Platinum Card provides access to the Delta Sky Club, but 2026 has introduced stricter usage caps. As of February 2025/2026, cardholders are limited to 10 visits per year, unless they spend over $75,000 annually to unlock unlimited access. To enter, you must be flying on a same-day Delta-operated flight and present your card with your boarding pass. You can only enter within 3 hours of your departure (or anytime during a layover). In 2026, "Arrival Access" is no longer permitted for Amex Platinum holders. While it’s a high-value perk, it is now more of a "strategic" benefit for occasional travelers rather than a daily haunt for frequent flyers, helping Delta manage the significant overcrowding seen in previous years.
