Important Changes to Delta Comfort+™
Because Delta Comfort+™ is now a separate fare, the upgrade policy has changed. Similar to First Class, Medallion members are eligible for complimentary upgrades if they opt in. Upgrade preferences can be managed in My Trips.
Based on availability, Diamond and Platinum members are eligible to receive a complimentary upgrade at any point after they have opted in. Gold Medallion members may receive an upgrade within 72 hours of departure, and within 24 hours for Silver Medallion members. Upgrades are automatic, and customers will be notified via email.
