I've got a Sentri card but when I got to the Global Entry station at LAX I was told that I wasn't allowed to enter. This seems to be in contradiction of the "For NEXUS and SENTRI Members at Global Entry Kiosks" section on the Global Entry website (though it is a bit confusing).
Does anyone have any experience with this? Can someone explain what to say so that I can use Global Entry with my Sentri card?
