Daughter and her boyfriend arrived Schipol at 8:35 with carry on only and boarding passes in hand. They were through security exactly three hours later. Passport control only took a few minutes. They said that there was someone checking boarding passes to make sure you were not getting there more than four hours before your flight. IcelandAir is holding its flight right now waiting for passengers. Delta to Boston is also delayed (they are on separate flights) due to waiting on pushback slot and ground control checking for passengers.
