I hope nobody minds me sort of asking a follow on question regarding medallion upgrades.

Is DTW a "smaller" hub? I've flown through ATL once or twice and it clearly requires GM or better to have any real chance at upgrades, but what about DTW? I routed through LGA since I felt I'd have a good shot on at least 2 of my 4 flights, but I'm now kicking around SDC through DTW but don't know if it'll hurt my chances vs LGA.

Thanks!
