“Are these guys OK?” one person asked, posting a photo of the aircraft’s flight path to social media platform Reddit.
Engineers in Auckland “troubleshooted” the issue, a Qantas spokesperson said, and the flight departed at 10.30am.
It is scheduled to arrive in Brisbane just before midday AEST. There are no further disruptions to the schedule, with the next flight booked to depart Auckland International Airport at 6.25am tomorrow.
A flight can be diverted for many reasons and either return to the departing airport or emergency landing somewhere else.
In February, an Air New Zealand flight diverted to the Pacific island of Guam due to an “unidentified odour” in the cabin, and in April another Air New Zealand flight returned to Auckland after departing to Tahiti due to an issue with the aircraft’s hydraulic systems. In this instance, the airline knew it had a better chance of solving the issue in Auckland.
It isn’t unusual for a diverted flight to circle around a city before landing. In January, a Qantas flight from Christchurch to Melbourne was forced to fly four circles above Raglan before it could land at Auckland Airport.
