Great timing as I was actually just about to look for the right thread to ask this… but this year is my first as GM and I’m just trying to understand how the 72 hour upgrade window works.

Are upgrades in the window automated to clear if there’s room for upgrades (assuming I’m high enough on the list), or does it require someone at Delta to actually process the upgrade?

Also, is there any notification when the upgrade clears? My only experience so far has been upgrades at the gate, but if I clear before even checking in there won’t be an agent or screen to announce it.
