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.

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

The Denver outage is the latest in a series of glitches that have put a spotlight on the nation’s aging air traffic control system.

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.

Tech chaos at Newark Liberty airport saw a spike in cancellations and delays in recent weeks, disrupting one of the busiest airports in the United States.
