The FAA is holding a “delay reduction” meeting Wednesday, seeking to cap the total number of flights at the airport.

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

A portion of the Denver air route traffic control center experienced a 90-second loss of communications late Monday, the Federal Aviation Administration said in a statement.

Recent communications issues at the FAA facility handling flights in and out of Newark airport were not new, officials say. Outages happened at least three times last year. CBS News senior transportation correspondent Kris Van Cleave has more.

A staffing shortage, runway construction and deferred maintenance to crucial air traffic technology have made Newark Airport a national laughingstock.

Duffy laid out an extensive plan to replace the nation’s outdated air traffic control system last week, including installing 4,600 new high-speed data connections and replacing 618 radars, but didn’t put a price tag on the plan other than to say it will cost billions.

The meeting comes after weeks of cancellations and delays at Newark Airport due to staffing shortages and runway construction.

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