United Continental Holdings, the parent company of United Airlines, entered into a non-prosecution agreement with the U.S. Attorney’s Office as part of a case in which David Samson, the former chairman of the Port Authority of New York and New Jersey, pleaded guilty to bribery for pressuring United to reinstate a non-stop flight route between Newark, New Jersey, and Columbia, South Carolina, for his personal benefit. United paid a $2.25 million penalty and agreed to cooperate with and report periodically to the U.S. Attorney’s Office for two years.
