I was on the EK (morning arrival into JFK) last month ........... No queue at all. Was out of there in a flash ......... Those booths were operational (where you do your finger printing etc etc.,) but it didn't work too well - I had to get the usher's(what do you call the random dude who's walking around?) help me with it.
Fast Track - hahaha ..........Unfortunately, the US airports are backward and sub par.
