Experts weigh in on what travelers can do if facing delays or cancellations, and how to be proactive for upcoming flights.

Newark Airport reportedly experienced another outage Sunday, resulting in a temporary ground stop at the facility. Newark has been besieged with problems over the last few weeks, including multiple air traffic control equipment outages and widespread delays and cancellations of flights.

A 45-minute-long ground stop at Newark Liberty International Airport has been lifted. The ground stop was put in place by the FAA in response to an air traffic control equipment outage. This outage comes after two similar equipment outage incidents – one on April 28 and the other on May 9.
