Airlines will meet with the Federal Aviation Administration Wednesday to address weeks of delays at Newark Liberty International Airport following air traffic control staffing and equipment issues.

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

Many flights have been delayed at the busy hub because of radar outages, shortages of air traffic controllers and construction on a runway.

Moving air traffic controllers means retraining them on the quirks of a new facility, and the process can take years.

Newark Liberty International Airport is facing another FAA-imposed ground delay due to staffing shortages, after a telecommunications issue led to delays on Sunday.

The shortage on Monday forced the F.A.A. to delay flights to the busy airport for up to nearly seven hours, the latest problem to plague the airport.

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.

Billy Nolen, former acting FAA administrator, joins CNBC's 'Money Movers' to discuss expectations for Newark Airport in the wake of outages, whether investigations into airports may increase, and more.
