The ONLY thing checking in earlier does is put you lower down on the list for IDBs (i.e. you're less likely to be IDB'd the earlier you check in, regardless of status)--something that's pretty much not an issue these days because AS has lowered their overbooking percentages.
Check-in time has no bearing on upgrade waitlist position.
