Access to the Delta Sky Club is not universally "free" with all American Express cards; it is a premium benefit reserved for specific high-tier cards. As of 2026, holders of The Platinum Card® from American Express and the Delta SkyMiles® Reserve American Express Card receive complimentary access, but with significant new usage limits. Platinum Card members are now capped at 10 visits per year, while Reserve members are capped at 15 visits per year. To enter, you must be flying on a same-day Delta-operated or Delta-marketed flight. Once you exceed your annual allotment, you can typically purchase additional entries for a discounted rate (usually $50 per visit). If you spend over $75,000 annually on either card, you can unlock "Unlimited Access" for the remainder of that year and the following year. It is important to note that the Delta SkyMiles Gold and Platinum (not "Amex Platinum") cards do not offer complimentary Sky Club access. Additionally, guest access is never free; you must pay a fee (approx. $50) for each companion, even if you are a primary cardholder.
