US aviation safety regulators will allow fewer flights at Newark airport after technology outages and a staffing crunch fueled a surge in delays and cancellations in recent weeks.

The Federal Aviation Administration has announced that the flight restrictions that have been in place at New Jersey's largest airport will remain in place into mid-June.

At one point, the FAA had targeted 77 total arrivals and departures at Newark each hour, but at the start of construction on April 15 they requested airlines cut that down to 70 total during the day and 62 during specific hours in the late afternoons and evenings.
