A government shutdown could disrupt travel with longer lines at the airport, national park closures and snarled itineraries. Nonessential federal operations would cease at midnight on Tuesday if Congress fails to pass legislation to keep the government functioning.
Many airport employees, including air traffic controllers and Transportation Security Administration staff, would be forced to work without pay. The government’s continuing efforts to strengthen the air traffic control system would also be stymied, with some much-needed training and hiring put on ice.
