Odd. For me once I have applied the PointsPlus I no longer have the Upgrade Learn More button displayed at the top of the reservation details page. And when I open the seat map and try to choose a Polaris Seat the pop-up bubble says that upgrades are available to this type of seat and upon selection it will take me to the Upgrade page to view upgrade options. After clicking to go to that page all options listed show as No Upgrade Available (Money, Miles, PointsPlus). I get the PointsPlus not being available as I have already submitted a waitlisted request, but I wanted to see how much they are offering for the cash upgrade to Polaris to see if it is a good offer. For reference, this is an international long-haul flight with multiple people on the reservation, One 1K (me) and three Silvers (my children).

Maybe I will cancel the request and see if that causes the cash upgrade offer to display again.
