Amex Platinum cardmembers get access to Delta-operated Sky Club lounges when flying on a Delta-operated flight or a Delta-marketed flight operated by WestJet. To find eligible lounges, head to Delta's website and select Platinum Card® Members From American Express as your membership type.

Yes, the American Express Platinum Card provides access to the Delta Sky Club, but the rules have become significantly more restrictive as of February 1, 2025/2026. Cardholders currently receive 10 visits per year to the Delta Sky Club when flying on a same-day Delta-operated or Delta-marketed flight. To "unlock" unlimited access, you must spend at least $75,000 on your Amex Platinum in a single calendar year. It is important to note that you cannot use these visits for guests; any guests (up to two, or immediate family) must pay a per-visit fee of $50 each. Additionally, you can only access the lounge within three hours of your flight's departure (unless you are on a layover). In 2026, this remains one of the card's most popular perks, but the "10-visit cap" has made it essential for travelers to strategically choose which lounges they visit during their trips. Access is not granted if you are flying with any other airline, even a SkyTeam partner like Air France, unless the flight is specifically "marketed" by Delta.
