Just like clearing immigration through the GE kiosk, you will have access to a special lane to clear customs. Last month in charlotte, the line to clear customs was over 100 people deep with 1 customs officer to go through. With GE, we went to the left for people with GE and skipped that line and handed our GE receipt and passport to the officer and we were out through C/I in minutes where everyone else had a good 30-45 mins since multiple flights had arrived at same time.
