The authority cautioned that the lifting of the ground stop does not mean an immediate return to normal operations, as airlines are likely to face continued disruption while clearing the backlog of affected passengers.
Airlines are working to rebook passengers whose travel plans were affected by the suspension, with knock-on delays expected as operations gradually return to normal.
The FAA grounded all departing flights across the country for only the second time since the September 11, 2001, attacks, citing "extraordinary circumstances" triggered by communications problems at regional air traffic control centres.

The outage appeared to have affected a telecommunications network managed by L3Harris Technologies, which handles critical radio frequencies used by air traffic controllers to communicate with pilots, a Wall Street Journal report said. However, it remained unclear whether the disruption had also affected radar feeds used to maintain safe separation between aircraft during flights.
The ground stop caused widespread disruption at several major US airports, leaving thousands of passengers stranded in long queues as they waited for updates on their flights. More than 1.5 million people were scheduled to travel on flights after the pause took effect, according to aviation data firm Cirium.
