Airline has trimmed its daily routes following technology and staffing issues affecting New Jersey hub.

The FAA is working on a short-term fix to the problems at Newark Airport that includes technical repairs and cutting flights to keep traffic manageable while dealing with a shortage of controllers.

The airline told the Sun the e-mail was sent to passengers who have upcoming flights to or through Newark’s airport, as well as its MileagePlus

Caught in the middle of the issues at Newark is United Airlines, which is the most active airline at the New Jersey airport. While the problems lie with the FAA system, the airline is where people often aim their frustrations over cancellations and delays.

By Rajesh Kumar Singh CHICAGO (Reuters) -United Airlines is facing a financial hit and potential long-term reputational harm as flight delays and cancellations pile up due to ongoing disruptions at Newark airport - one of its largest hubs and among the busiest in the country.

Staff shortages and equipment failures at Newark Liberty International Airport have raised safety concerns in recent weeks.

One air traffic controller (ATC) and a trainee will operate every flight in and out of Newark between 6.30pm-9.30pm — despite 15 staffers being the standard requirement for a shift.

"We've turned the corner, and we have the commitment," United Airlines CEO Scott Kirby said of reforms to the Federal Aviation Administration.
