Major Delays at Orlando International Airport as All U.S. Flights Grounded Early A.M. Due To Outage

FAA grounded all US flight departures early this morning during nationwide system failure causing massive disruptions at airports across the US.

Earlier this morning a Federal Aviation Administration system that provides pilots with notices they need to read before flying experienced an outage, affecting all flights in the US.

The FAA ordered airlines to pause all domestic departures until 9 a.m. Eastern Time to allow the agency to validate the integrity of flight and safety information.

The latest numbers from flight-tracking site FlightAware show more than 4,000 delays and nearly 700 flight cancellations across the US.

The disruptions come after an outage of the Notice to Air Missions system, which provides pilots with safety notices they need before flying.

Airports are now only beginning to see flights departing although serious delays and cancelations are expected throughout the day.

Here in Orlando, Orlando International Airport tweeted an update advising passengers to check with their airlines for travel updates.

"Please check with your airline directly for the most up-to-date flight information prior to your travels and follow @FAANews for the latest update in regards to their system outage. Thank you."

At 8:50 am, Orlando International Airport gave an update saying "Normal air traffic operations are resuming gradually across the U.S. following an overnight outage to the Notice to Air Missions system that provides safety info to flight crews. The ground stop has been lifted."
