Hundreds of flights have been delayed or canceled at Newark Liberty International Airport due to a ground stop and ongoing construction.

The airport is experiencing significant disruptions, with two main reasons contributing to the issues.

The airport's three runways are not fully operational due to construction, with one runway being resurfaced and getting new lighting. This runway closure is expected to last until June.

Additionally, staffing issues among air traffic controllers in the flight tower are causing major delays for both departures and arrivals.

The FAA warns that some arriving flights might be delayed by up to five hours.
