International meaning US/non-Schengen? If so, you are more likely to exit through the main arrival hall, which is basically on the ground floor, just below CDE. What you will need to do is proceed right as soon as you exit the baggage hall, straight ahead until you see another arrival area with flight information screen (you should see a McDonald Café and McDonald Restaurant within that hall), there you will go up the stairs and you will be in the AB's departures hall. It all sounds complicated but it's just matter of 30 seconds once you're there.

Any doubts, please let me know.
