With summer travel season approaching, the crisis at the New Jersey airport could mean weeks, if not months, of misery for travelers.

United Airlines, which flies the most from Newark, has cancelled 35 round-trip flights per day to help ease pressure on the airport.

Delays and cancellations at Newark Airport have raised questions about whether a shortage of air traffic controllers and technological issues could fuel travel disruptions elsewhere.

The interim rule will cap the number of arrivals and departures at Newark Liberty International Airport at 28 apiece per hour. That’s in line with the limits imposed after about half a dozen controllers went on a 45-day trauma leave following the first outage on April 28.
