From the domestic gates to T3 should take you 45 minutes or so by airside bus. So at that point, if the flight is on time you should have 20 minutes or so in the T3 lounge. The only real problem is if the ABZ flight is delayed, you have about 20 - 30 minutes slack only. Just have your boarding pass for the USA ready on leaving the ABZ flight, they will check it after leaving the jetty and going through the glass doors for Flight Connections.
