10,000+ US flights delayed, canceled: ‘I’m frustrated, but I smell like passion fruit’

A computer glitch at the Federal Aviation Administration delayed airline traffic across much of the nation early Wednesday, and the agency said it was investigating what caused the issue as flights resumed.

The FAA instituted a nationwide pause on departures, known as a ground stop, for about 90 minutes Wednesday morning, but that order had been lifted by 9 a.m. ET.

Just  before 8:30 p.m. ET, more than 10,000 flights within, into, or out of the U.S. were delayed according to the flight-tracking website FlightAware, and more than 1,300 flights in the country were canceled. With 19,621 domestic flights scheduled on Monday, according to Cirium data, those numbers have been rising as airlines recover their operations.

On Wednesday afternoon, NAV Canada, the country’s air traffic control organization, posted a tweet saying its NOTAM system was experiencing technical issues as well, but added that the problem was not resulting in flight delays so far.
