Original Article (11:44 a.m. Tuesday): Authorities are investigating a suspicious package at Ronald Reagan Washington National Airport.
Airport operations and the Metropolitan Washington Airport Authority police this morning responded to an unattended item on the airport's ticketing level.
"Out of an abundance of caution, while the police investigate, they've cordoned off the area," said Lori Weaver, a spokeswoman for the airport authority.
Traffic on the airport's departure level has been rerouted to the arrival level. Washington National's concourse level remains open, Weaver told Patch at about 11:15 a.m. Tuesday.
Flight operations are proceeding normally, she said.
Arriving passengers should allow extra time to travel to the airport because of traffic being rerouted to the lower level, she said.
