On July 24, 2020, US Customs and Border Protection (CBP) published in the Federal Register a final rule and technical amendment [CBP Dec. 20-10] that amends CBP regulations (in 19 C.F.R. 122.15(b)) by revising the list of user fee airports to reflect the designation of user fee status for four additional airports: New York Stewart International Airport in New Windsor, New York; Lakeland Linder International Airport in Lakeland, Florida; Boca Raton Airport in Boca Raton, Florida; and Ontario International Airport in Ontario, California. User fee airports are those airports which, while not qualifying for designation as international or landing rights airports, have been approved by the Commissioner of CBP to receive, for a fee, the customs services of CBP officers for the processing of aircraft entering the United States, and the passengers and cargo of those aircraft.
