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.

Hundreds of flights were canceled or delayed at Newark Liberty International Airport over the weekend and again on Monday as shortages of air traffic controllers persists, causing flight disruptions at one of the nation’s busiest airports.

United Airlines says it will cancel dozens of Newark flights per day after this week's delays and FAA staffing problems.
