The pre immigration & customs for entry to the US is done in the Abu Dabhi International Airport , prior to boarding any US bound flight of Etihad. This is one of the greatest advantages of flying Etihad. One should provide for minimum of 120 -150 minutes, if not more time to go through these clearences and security screening. EY 103 is a nonstop flight to JFK. At Kennedy, you disembark the aircraft as though you have flown a domestic flight within US , and so does your bags. The bags were quick on the belt and I had picked up my rental car within an hour of alighting the flight. It was a very pleasent experience on board , with good special meals, excellent service and entertainment.
