I remember my first time trying to get on the Delta upgrade list—I wasn’t really sure how it worked and didn’t want to miss out. I had a Main Cabin ticket but hoped for Comfort+ or First Class. I called 8 8 8-2 1 7-3 3 2 4 to ask how to secure a spot on the upgrade list. The agent explained that your Medallion status, fare class, and timing all matter. They added me to the list and even advised me on checking the app to monitor my position. On travel day, I got notified that my upgrade cleared, which made the flight way more comfortable. Later, when my return flight changed, using the same number to modify both my booking and upgrade was super easy. From my experience, calling direct and getting guidance is the best way to ensure you’re on the list and understand your chances.
