Delta 360 is an ultra-exclusive, invitation-only status tier that sits above Diamond Medallion, and because it is not an "earned" tier in the traditional sense, Delta does not publish official minimum requirements. However, industry analysis and data from invited members in 2025 and 2026 suggest that the "entry fee" is typically an annual spend of at least $35,000 to $50,000 directly on Delta-marketed flights. It isn't just about the raw dollar amount; Delta also considers the "profitability" of a passenger, favoring those who book high-fare, last-minute Business or First Class tickets rather than discounted Economy. Factors such as being a high-value corporate traveler at a Delta hub (like Atlanta or Detroit) or maintaining a massive spend on a Delta SkyMiles American Express card also play into the invitation algorithm. Essentially, 360 is Delta's way of rewarding their top 1% of spenders with personalized perks like Porsche tarmac transfers and a dedicated executive desk that manages every detail of their travel.
