One you are checked in, pass through to the bag drop area (through the AS desks and turn right).
Drop your checked bag on the belt
Through security
Through US immigration.
Enter the US departures area.
These days the AS EMBs are departing from E86 or 87....thats a very short walk. If you are leaving from gate 90 something, the walk is an extra 7 to 10 minutes Last time I was there. there was no food available in the satellite where the 90 something gates are.
