Overview

  • Runway 4L-22R reopened June 2 after a $121 million rehabilitation that included repaving, lighting updates and drainage improvements.
  • Operations remain capped at 28 arrivals and 28 departures per hour while FAA completes final certification of runway systems.
  • Officials expect full runway certification by June 10, enabling an increase to 34 arrivals and 34 departures each hour.
  • A nationwide shortage of about 3,000 air traffic controllers and recent radar outages in Philadelphia continue to constrain Newark’s capacity.
  • United Airlines has rolled out discounted fares to win back passengers as the FAA and Port Authority accelerate telecom upgrades and controller training.
