Beginning Tuesday, Dulles International Airport serves as a gateway airport, eTurboNews reports, allowing such air operations as corporate aircrafts, charter flights and on-demand operations to fly directly into Ronald Reagan Washington National Airport, or DCA. "We are being responsive to the aviation industry by adding Dulles as a gateway to DCA," said John Sammon, the Transportation Security Administration's assistant administrator of transportation sector network management. "This provides operators much greater flexibility when traveling to the nation's capital while underlining TSA's commitment to maintain the highest levels of security while allowing for the free flow of commerce."
