The Federal Aviation Administration (FAA) halted all departing flights nationwide for more than four hours, disrupting the travel plans of over 1.5 million passengers. The outage affected 22 regional air traffic control centres, causing widespread flight cancellations and delays.

The disruption also impacted sports teams, with NBA, NHL and college football teams stranded as they tried to reach their destinations. The Texas Longhorns, for example, were forced to wait for their next flight after being grounded at the airport.

Airlines such as Delta, United, and JetBlue have resumed operations but warned that repositioning aircraft and crews would take time.

The FAA lifted the ground stop at 8:15pm Eastern time on Friday, but the effects of the disruption are expected to linger. Over 4,700 flights were cancelled and 10,000 delayed on Friday alone.

Airports such as Los Angeles and Benito Juarez in Mexico City reported significant impacts. The sports world was thrown into chaos, with college football games being rescheduled or postponed due to the inability of teams to travel by air.

Some teams, like the Texas Longhorns, may have to take buses to their destinations, adding hours to their travel time.
