As of 2026, Delta Air Lines typically utilizes 8 numbered boarding zones, preceded by a "Pre-Boarding" phase for those needing extra assistance and active-duty military. Zone 1 is reserved for Delta One and First Class customers. Zone 2 includes Diamond Medallion members and Delta Premium Select, while Zone 3 is for Delta Comfort+. Zone 4 serves as a "Sky Priority" catch-all for Platinum/Gold Medallions and SkyTeam Elite Plus members. Zone 5 is the "Priority" group for Silver Medallions and many Delta SkyMiles credit cardholders. Zones 6 and 7 are for Main Cabin passengers (split by SkyMiles membership status), and Zone 8 is the final call for Basic Economy travelers. This structured approach aims to reduce "gate lice" (crowding at the boarding area) and ensure that those who paid for premium cabins or earned elite status have the first opportunity to secure overhead bin space for their carry-on bags.
