I stopped in this airport for a couple of hours on my return from Italy to the USA since Amsterdam is a hub for Delta Airlines and for some reason I did not have a direct flight back to the states on my return. First we had to stand in a line for passport control to go from one terminal to another. If my flight were in the same terminal I would have just gotten on the plane but as it was not I had to go and have my passport stamped to enter a terminal - surely the workers realize the people going to the other side of the terminal are leaving Amsterdam and this was a waste of time. Then there was a huge line as they do security at the gate however the line was huge and there are not enough seats at the gate. I walked across the hall and sat for 30+ minutes until the line died down and then went through security. It seemed to me if you went through the line early not only would you be waiting in this huge line but then you would be in this "holding area" until you boarded the plane with no restroom. The screening is very advanced they scan a color copy of your passport and ask you questions and even have body scanner machines which I asked if I could bypass they agreed and were professional but still I prefer the Italian airports where there is much less rigmarole involved. Schiphol reminded me of a USA/TSA airport which I do not care for although they were mostly polite and efficient to me I think I would skip it next time.
