I'm looking at this flight <72 hours out and the seatmap looks like this:



and the upgrade list looks like this:



I'm pretty bummed I won't have my status back until after this trip, because I could probably clear this upgrade on a transcon even as a lowly MVP! What are the chances that they sell upgrades to first? And how much do they go far, typically? I remember at one point there was a flat cost based on the mileage, do they still do that? Can you use wallet credits to pay for the upgrade?

It looks like they've made U space available, but unfortunately I don't have access to any GGUs.
