The US Federal Aviation Administration lifted its nationwide ground stop Friday (local time), ending a halt on all departures across the country.
Flights from Incheon to the United States moved to resume normal operations after cancellations were reversed.
The FAA lifted the ground stop roughly four hours and 20 minutes after it took effect, Yonhap and Reuters reported.
Aviation outlet The Air Current said the FAA's ground stop was lifted at around 8:15 p.m. Eastern time Friday (10:15 a.m. Korean Standard Time Saturday).
Some Korean Air and Asiana Airlines flights on US-bound routes from Incheon that had been canceled also moved to resume normal service.
Earlier, Korean Air had canceled flights on its Incheon–Atlanta route (KE033 and KE034), while Asiana Airlines canceled its Incheon–New York service (OZ221 and OZ222) the same day.
Meanwhile, the FAA had earlier halted all departures nationwide due to what appeared to be a failure in air traffic control communications systems. Local media reported the disruption stemmed from a communications problem at an air traffic control center and was not believed to be a cyberattack.
