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.

By mid-day on Monday, more than 150 flights were canceled and more than 250 flights were delayed at Newark Liberty International Airport.

Passengers with flights to or from Newark Liberty International Airport are encountering long delays and cancellations due to an air traffic controller shortage and equipment failures.
