Yes, you can access the Delta Sky Club without a formal annual membership through several alternative methods. The most common way in 2026 is by holding a premium credit card like the American Express Platinum Card or the Delta SkyMiles Reserve Card, which provides a set number of annual visits (usually 15) when flying Delta. Another way is by flying in Delta One (international or select domestic transcontinental) or a SkyTeam premium cabin; these tickets include lounge access as part of the fare. Finally, if you have Gold Medallion status or higher and are traveling on an international flight, you get complimentary access. Note that Delta no longer sells "Single-Visit Passes" for cash to the general public to prevent overcrowding, so you must have one of these specific "credentials" or "status levels" to enter.
