Yes, Delta Silver Medallion members are technically eligible for Unlimited Complimentary Upgrades to Delta One, but only on domestic flights within the U.S. 50 (such as New York-JFK to Los Angeles or flights to Hawaii). In 2026, Silver Medallions are at the bottom of the upgrade hierarchy, meaning they will only clear after all Diamond, Platinum, and Gold members have been accommodated. For Delta One, Silver upgrades typically only clear on the day of departure at the gate. It is vital to know that you cannot get a complimentary upgrade to Delta One on international long-haul flights (e.g., USA to Europe or Asia) regardless of your status tier; those require the use of "Global Upgrade Certificates" or miles. If you are a Silver Medallion, your best chance for a Delta One seat is on a "red-eye" flight or a mid-week flight to a non-hub city where there are fewer high-tier business travelers. Always ensure you have "requested" the upgrade in your flyDelta app profile to be automatically added to the standby list.
