The FAA's nationwide ground shutdown continued to disrupt U.S. air travel Saturday, with nearly 3,300 flights canceled and nearly 1,000 delayed as of 5:15 a.m. ET.
Airlines are struggling to recover from Friday's disruption, with millions of passengers facing ongoing delays and cancellations.
The disruption has renewed attention to the antiquated technology underlying America's air traffic control system; US Transportation Secretary Sean Duffy has requested $50 billion in emergency funding to modernize the system, with Congress now under pressure to respond to the request.
