QUEENSTOWN, New Zealand — A Qantas jet flying from Queenstown to Sydney was forced to divert to Christchurch on Saturday after witnesses reported flames bursting from its left-engine area and a series of loud bangs shortly after takeoff.
Flight QF122 landed safely in Christchurch at about 5pm on September 5, with firefighters and emergency vehicles waiting for the Boeing 737-800. Qantas described the incident as a “suspected engine issue” and said its pilots were trained to manage such situations.
No injuries were reported in the information available after the landing. Passengers, however, faced an unexpected stop in Christchurch instead of Sydney, with Qantas arranging support and onward travel.
What happened to Qantas QF122?
QF122 was scheduled to leave Queenstown at about 3.35pm and arrive in Sydney at approximately 4.50pm local time.
Not long after departure, residents around Frankton heard a succession of unusually loud sounds from the aircraft. Ground footage showed repeated orange flashes or flames near its left engine as it climbed away from Queenstown.
One witness compared the popping noises to gunshots. Brothers Daniel and Campbell Longmire, who watched the aircraft from Frankton, described several bursts of flame accompanied by loud bangs. Campbell estimated seeing around six or seven flame bursts.
The dramatic scenes prompted people in the area to come outside and watch the aircraft as it continued flying.
Why did QF122 divert to Christchurch?
Instead of continuing across the Tasman Sea to Sydney, the pilots headed to Christchurch.
Qantas has not publicly explained why Christchurch was selected rather than returning to Queenstown. Without an official explanation, claims about the specific operational reason for that decision would be speculation.
Aircraft diversions can significantly alter passenger journeys even when emergencies end safely. Travellers recently faced another example when an aircraft stuck on the runway disrupted flights at Gatwick Airport, forcing diversions and delays.
Emergency crews meet Qantas jet in Christchurch
Firefighters were positioned at Christchurch Airport before QF122 arrived, a standard precaution when an incoming aircraft reports a technical problem.
The jet subsequently made what Qantas described as a safe and normal landing. Footage showed emergency vehicles near the aircraft after touchdown, while smoke appeared to be visible around the left-engine area. The source of that smoke has not been officially confirmed.
Qantas acknowledged that the incident would have been distressing for passengers and said customers would be contacted and supported.
Passengers to be rebooked after QF122 diversion
Passengers who expected to arrive in Sydney instead found themselves in Christchurch and needed new travel arrangements.
Qantas said affected customers would receive support. New Zealand reporting said accommodation would be provided where required and passengers would be rescheduled onto other flights.
Customers should check direct airline notifications and the official Qantas flight status page for individual itinerary changes.
Major aviation disruptions can also affect passengers well beyond the aircraft directly involved. That was evident when severe flooding disrupted flights and transport across Toronto, highlighting why travellers should monitor airline updates during rapidly changing events.

What aircraft was involved?
The aircraft operating QF122 was reported to be a Boeing 737-800 about 15 years old. The twin-engine narrow-body aircraft type is widely used for short- and medium-haul services, including trans-Tasman flights.
The unfolding incident attracted intense interest on flight-tracking services. QF122 became one of the most-tracked aircraft on Flightradar24 as thousands followed its diversion toward Christchurch.
Queenstown Airport, meanwhile, confirmed that it remained operational following the departure.
Did Qantas QF122 suffer an engine fire?
An engine fire has not been officially confirmed.
Videos and eyewitness accounts establish that flames were visible around the left-engine area and loud bangs were heard, but Qantas has so far characterized what happened as a suspected engine issue.
That distinction matters. The appearance of flames alone cannot determine the precise mechanical problem. Suggestions of a bird strike, compressor problem or another specific failure remain unconfirmed, and Qantas has not publicly said whether the affected engine was shut down during the diversion.
The aircraft will need technical examination to establish what caused the abnormal engine behaviour. Until more information is released, the confirmed sequence is that QF122 encountered a suspected engine issue after leaving Queenstown, diverted to Christchurch and landed safely with emergency crews standing by.
