December is the busiest month for the UPS Worldport in Louisville, as the facility processes over 4 million packages a day during the holiday shipping season.
Even on a regular month, UPS processes over 2 million per day. The website Transport Topics says that makes Louisville’s Muhammad Ali International Airport the third busiest cargo airport on the continent.
