Jetstar passengers awoke on Saturday 29 November to dozens of cancellations and delays after Airbus issued an overnight directive ordering immediate software reversions on thousands of A320-family aircraft worldwide.
The recall follows an incident on a JetBlue service in the United States in which corrupted flight-control data—believed to have been triggered by elevated solar-radiation activity—caused a sudden altitude loss. Airbus engineers traced the problem to an interaction between the flight-management guidance computer (FMGC) and the latest navigation-database architecture. Until a permanent patch is certified, operators must roll back to the previous software load.
![Jetstar Grounds 34 Airbus A320s After Global Software Recall, Cancelling 90 Flights Nationwide]()
Jetstar confirmed 34 of its 85 A320s required the two-to-three-hour update, forcing the low-cost carrier to cancel about 90 domestic services and a handful of short-haul international flights. The disruptions were heaviest in Brisbane, Sydney and Melbourne, stranding thousands of travellers at the start of the summer peak. By late afternoon, 20 aircraft had returned to service, with the remainder expected to be cleared by Sunday. Qantas and Virgin Australia, whose smaller A320 sub-fleets run mainly charter and regional routes, reported no operational impact and offered spare capacity where possible.
Aviation analysts say the incident highlights the growing cyber-physical complexity of modern fleets and the importance of rigorous change-management protocols when updating aircraft software. For corporate travel managers, the takeaway is the need for real-time disruption monitoring and flexible re-booking frameworks—even when issues originate off-shore. Travel-risk teams should also note the increasing role of space-weather events in aviation resilience planning, with experts predicting a surge in geomagnetic activity as the solar cycle peaks in 2026.
Jetstar is providing affected customers with fee-free re-accommodation or refunds and has urged passengers booked through the weekend to check flight status before leaving for the airport. Airports and ride-share operators are bracing for flow-on effects on Sunday, when aircraft rotations and crew hours are expected to remain out of position.
