Hate to say it but I think you are lucky..get there at lunchtime when many flights seem to leave and you be in long lines before you get through. I would always leave a 2 hour minimum more like 2 and a half..this last time through was a loooong haul. One thing we do to speed things up is get a second c and i form from the ferry company so we are ready to go right through to c and i at the airport..
