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 said Friday it plans to announce proposed temporary cuts to flights at Newark after meetings with major U.S. airlines to address congestion impacts.

United Airlines has sharply cut flights at its Newark hub and wants the FAA to impose new limitations on flights there to address ongoing delays. United said on Tuesday it expects to temporarily cut a few additional flights. Newark has also been hit by a series of telecom outages.
