I am the only person on the reservation. Because of the routing (first flight from Singapore) the flight is KLM / Delta-operated. Maybe that makes a difference? But it won't let me Modify Flights and make the change.
Also, I called the PM Line where they worked on it for a while and said it was "fixed now", but everything appears the same. All Xs and no Manage Upgrades.
At least part of the answer is here:
Complimentary Upgrades on DL Metal when booked on a AF/KL/VS Codeshare Flight
