US Prepares Air-Traffic Overhaul as Vulnerabilities Rock Newark

The Trump administration’s plan to modernize the aging US air traffic-control system has gained fresh urgency after vulnerabilities with the existing system pushed United Airlines Holdings Inc. to cut flights at the second-busiest hub serving New York City.

Transportation Secretary Sean Duffy aims to release his proposal this coming week for a new system for the Federal Aviation Administration to manage the roughly 45,000 US flights that carry about 2.9 million passengers in the US each day. The plan is set to include upgrades to air traffic control systems and facilities, which will require billions of dollars in new funding from Congress.
