New Delhi: Air travellers across the world are facing mounting delays after Airbus announced an urgent software update for more than 6,000 A320 aircraft, prompting widespread flight cancellations and operational disruptions. Aviation authorities and airlines have warned passengers that delays could last from several hours to, in some cases, more than a week.
The advisory followed a technical investigation by Airbus into a JetBlue incident last year, when an A320 flying from Mexico to the United States suffered a sudden computer malfunction mid-air. The aircraft’s nose pitched downward before the pilot made an emergency landing in Florida. Subsequent analysis found that intense solar radiation had interfered with the aircraft’s onboard data systems.
In response, Airbus has issued a global directive requiring airlines to install updated software across the A320 fleet. While the update will take only a few hours for most aircraft, around 1,000 planes may require up to a week to complete the process, potentially disrupting schedules for weeks.
A statement by Airbus says, “Analysis of a recent event involving an A320 Family aircraft has revealed that intense solar radiation may corrupt data critical to the functioning of flight controls.

The impact has been immediate: Air France cancelled 35 flights, while Japan Airlines grounded 65 services. In India, both Air India and IndiGo have issued advisories alerting passengers to possible delays and cancellations.
According to the European Union Aviation Safety Agency (EASA), the update could affect as much as 70% of European airline operations. “Passenger inconvenience is unavoidable, but safety remains our highest priority,” the agency said.
The A320 family is among the most widely used aircraft in global commercial aviation, meaning even short-term disruption has far-reaching consequences. Airlines are working to reschedule flights, arrange replacement aircraft where possible, and communicate delays, but officials cautioned that travellers should brace for continued uncertainty in the coming days.
Airbus has urged airlines to complete the update “as quickly as operationally possible” to ensure fleet safety and prevent further incidents linked to radiation-induced data interference.
