The disruptions at Newark Liberty International Airport continue with delays and cancellations, after more than 500 flights were impacted Sunday. As of 8:30 a.m. Monday, the airport reported 20 delays and 73 cancellations,

The shortage of certified air traffic controllers in the US has led to flight disruptions and headaches for travelers across the country, most recently at busy Newark Liberty International Airport in New Jersey,

The delays and cancellations are a response to continued air traffic control staffing and equipment issues at the FAA facility in Philadelphia, which oversees Newark's airspace.
