The Federal Aviation Administration is ordering flight schedule reductions at Newark Liberty International Airport (EWR) amid ongoing air traffic control challenges and runway construction.

The Federal Aviation Administration said on Tuesday it would require flight cuts at Newark, one of the main airports serving New York City, after it met with U.S. airlines to address congestion issues following a series of major disruptions.

The New Jersey airport, which has faced radar problems and major delays, is scrambling to bring in more air traffic controllers and complete construction.
