I have ALWAYS gotten mixed answers about the INSPass. Yes, it's true - you can use them now that the Orange Alert is no longer.
I have used INSPass in LAX and sometimes it's working, sometimes it's not. The customs agents there really are clueless and when I got the new card a few months ago, the man there said there was NO intention of it being phased out - contrary to what MANY agents have told me in different airports - LAX, JFK, IAD, ORD, etc.!
