It's not a big deal – but I'm a little confused about Delta's checked baggage policy in the following scenario:

SYD->STL, (few days stopover) then STL->MDT, (few weeks) then MDT->SYD.

I suppose I will not be entitled to my international 50LB checked bag on the STL->MDT leg because it will be considered separate? I emailed Delta but they just gave me the generic checked baggage links.

Also, it seems Delta have changed their AU<->US policy of 2 checked bags at 50LB a piece – appears to be now 1 checked bag at 50LB a piece for anyone not a Silver Medallion member or above.. (economy).

EDIT: Actually, speaking of Silver Medallion status - my wife is a Silver Medallion, since we are flying together, can we go to the priority check-in desk in Sydney even though I am "General" scum?
