Check Houston flight status at IAH, Hobby: Delays expected nationwide amid FAA outage

HOUSTON - The Federal Aviation Administration has lifted a ground stop on flights across the U.S. following a computer outage early Wednesday that resulted in thousands of delays and hundreds of cancellations quickly cascading through the system at airports nationwide.

The FAA ordered all departing flights grounded early Wednesday morning, but lifted that order just before 8 a.m. CT.

However, delays and cancellations continued to snowball. More than 3,700 flights were delayed and more than 640 were cancelled.

In an update at 7:15 a.m. CT, the FAA said it was making progress in restoring the Notice to Air Missions system following an overnight outage.

"A Notice to Air Missions alerts pilots about closed runways, equipment outages, and other potential hazards along a flight route or at a location that could affect the flight," the agency wrote on Twitter.

Just before 8 a.m. CT, the FAA said normal air traffic operations were resuming gradually across the country, and they were still looking into the cause of the initial problem.
