I probably won't access the club at all after I cancel my reserve next fall. Though if it turns out I'm still putting the lions share of spend on DL next year when actively considering other options, I'll just buy a club membership outright (this is assuming they don't come up with some sort of other form of SC access for medallions and/or change the membership rules). I definitely enjoy and get a lot of value from the club, but a fair amount of it is voluntarily (SLC is extremely predictable for TSA so now I'll show up to the airport last min vs. getting there early to have a meal in the club and relax). and in the situations where I'm still going to have layovers, there's a decent chance I'll be on AA given the price differences vs. DL.
I don't think I even put 75k a year on a CC across all cards, and while I could find a way to put my mortgage on it to do so, the opportunity cost is just too high.
