Lately I've been finding that it takes the Delta system 5-10 minutes after confirmation of booking before the system upgrades me.
Also, unless you like to drink for free on the airplane, an "upgrade" to a middle seat in C+ is not necessarily an upgrade.
That said, I'm quite happy being PM; Delta still treats me well. Welcome to our ranks.
Thank you - am excited to be on board as a JFK flyer!
