Not sure how you manage to do so well as an MVP, but congrats you’re doing far better than me
anyways between the 2 I do far better on DL upgrades as a silver than AS upgrades as an MVP. I fly a ton between DEN and SEA and only get upgraded on Saturdays on AS, it’s fairly spread out on DL (though if I clear it’s always at the gate...never at the window).
That being said it really depends on the routes you’re flying to. If it’s transcon or midcon, your odds are pretty abysmal either way but I’d recommend AS, I’ve gotten a few surprise upgrades as MVP before but on DL anywhere mid or transcon out of SEA I’m usually 20th+ on the list. Even as Gold on DL unless you’re doing West Coast flying it’ll be rough out of the hubs
