Layover window for return flights?
 

Not sure if this is the right place to post... I'm looking at doing a mileage run to Jakarta (CGK), and currently, the flight deal has a flight that lands at CGK, and then the return flight leaves 80 minutes later. Do I need to go through customs? Wondering if this is too tight of a window to work with. Thanks!

From? What airline? Can you be certain that the same aircraft will be used for your next flight? If it's a once-a-day international flight, your probably ok, if not, you may be out of luck. You will go through immigration.
