Chicago : O'Hare : Terminal 1 : Fast Security checkin

Terminal 1 at the O’Hare International Airport in Chicago is dedicated to United Airlines flights and is one of the busiest terminals in the airport. Accordingly, it is a pain in the rear to get through security here. Try the security check-in at the extreme left of the terminal (next to the bag check-in counters) and you will be surprised, how empty and fast it is :).
