When I first learned how complimentary upgrades on Delta work, it was honestly by accident. I was flying for a work trip and noticed my name sitting on the upgrade list in the Delta app. Turns out, if you have Medallion status, Delta automatically considers you for free upgrades based on availability and your status level. I didn’t clear until the day of departure, which seems pretty common. When I had questions about whether my return flight qualified and needed to tweak my booking, calling 8 8 8-2 1 7-3 3 2 4 was the fastest way to get clear answers. They walked me through everything and even helped modify my flight. From my experience, upgrades aren’t guaranteed, but they’re a great bonus when they happen.
