Air passengers across the world were left checking departure boards this weekend after Airbus ordered urgent software repairs on around 6,000 A320 aircraft, forcing airlines to pull planes from service at short notice. The directive followed an alert from the European Union Aviation Safety Agency (EASA) after a JetBlue incident in October involving an unexpected drop in altitude. Investigators linked the problem to the Elevator and Aileron Computer, meaning affected aircraft must now receive a software realignment before flying again.
While Airbus insists safety has never been compromised, the sudden need to update thousands of jets has triggered a ripple of operational disruption – and passengers are already feeling the impact. Here’s a clear look at which airlines have confirmed they are affected, and what each carrier is saying.
US, Europe and Asia: Airlines issue travel warnings
In the United States, American Airlines, the world’s largest operator of the Airbus A320 family, confirmed that 340 of its 480 A320 aircraft require the software update. The airline said engineers were working through the process as quickly as possible, with the aim of limiting the number of delays. No mass grounding has been announced, but some schedule changes were unavoidable.
In India, Air India warned that part of its fleet would need immediate updates, meaning certain services could be delayed until each aircraft receives clearance. Low-cost giant IndiGo followed with a similar statement, confirming it is working with aviation regulators to carry out the precautionary updates, again cautioning that passengers may experience delays over the affected period.
Across Europe, disruption quickly spread. Lufthansa said a “small number” of cancellations and delays were likely over the weekend, pointing out that the required software work takes several hours per aircraft.
In France, the impact was more visible: Air France cancelled 35 flights following the directive as several aircraft were taken offline for maintenance.
In the UK, British Airways reassured customers that its operations remain largely stable. Only three BA aircraft are A320 models affected by the update, limiting any knock-on effect to the rest of its network.
Ireland’s national airline Aer Lingus also played down any serious disruption. The carrier confirmed that its A320 fleet is relatively small and that it does not expect major schedule problems while the software realignment is completed.
Meanwhile, budget airline Wizz Air said some delays were likely over the weekend as affected jets undergo maintenance, although the company has already booked immediate repair slots to return aircraft to service as fast as possible.
At easyJet, the news was more reassuring. The airline said that many of its A320 aircraft already had updated software, allowing it to continue operating most flights as scheduled and aiming for a swift return to normal service levels.
Latin America and the Pacific feel the ripple effect
Latin America has seen some of the most significant operational consequences.
Mexican carrier Volaris confirmed that its flights would face delays over the next 48 to 72 hours while affected aircraft undergo software updates.
Colombia’s national airline Avianca issued perhaps the strongest warning of all. The carrier halted ticket sales until December 8, citing expected major disruptions over the next 10 days. About 70 per cent of Avianca’s fleet is affected, placing it among the airlines hit hardest by the directive.
Another Mexican carrier, Viva, acknowledged that its operations would also be impacted by the required updates. However, the airline has not specified when it expects full service to resume, leaving passengers waiting for further guidance.
Further south, LATAM Airlines confirmed that the software update applies to A320 aircraft operated by its affiliates in Colombia, Chile and Peru. Jets operated in Brazil and Ecuador are not affected, according to the airline.
In the Asia-Pacific region, Air New Zealand announced that all of its A320neo aircraft were being updated, meaning Saturday flight operations would be affected as maintenance teams worked through the fleet.
By contrast, Brazil’s Azul said it was spared from the disruption – none of its A320 aircraft fall under the software directive, allowing the airline to maintain its full flying schedule.
Where things stand for passengers
Airbus has acknowledged that the mandatory checks would inevitably cause disruption for airlines and travellers alike. In a statement, the company said: “We apologise for the inconvenience this may cause and will work closely with operators, keeping safety as our number one priority.”
With thousands of aircraft moving through the update process, airlines are juggling schedules daily to minimise cancellations while ensuring safety compliance. Some carriers – particularly those with smaller affected fleets – expect only minor interruptions. Others, especially those with a heavy concentration of A320s, face days of operational instability.
For passengers, the message is straightforward: expect possible delays or last-minute changes, particularly with airlines that have acknowledged larger impacts such as Avianca, Volaris, Air France, American Airlines, Air New Zealand, and parts of the IndiGo and Lufthansa networks.
Travellers are advised to check flight status regularly, remain flexible with connections, and contact airlines directly for rebooking options where needed.
Behind the scenes, technicians are working flat out to clear aircraft for service, airline by airline. Until that work is complete, the skies remain busy – but not entirely predictable.
