US-bound flights out of Australia delayed after telecommunications outage grounded American planes

These include a Qantas flight to Dallas, and an United Airlines flight to San Francisco.

Flights to the US were also delayed at Brisbane Airport, where passengers on one US bound flight began boarding at around 1pm.
