Flights from Sydney and Melbourne airports faced delays as the US Federal Aviation Administration (FAA) halted all departures and delayed landings in response to a temporary telecommunications outage. Passengers on flights bound for Los Angeles and Dallas experienced significant delays, with one flight departing nearly three hours later than scheduled.

The FAA lifted the grounding order shortly before 1pm, but the impact on delays remained unclear. Airlines such as Qantas advised passengers to check their websites for updates.

Brisbane Airport also reported delays on four flights, though none were cancelled as of 2pm Saturday. The FAA continues to investigate the cause of the outage.
