Airbus is warning of potential travel disruption due to upgrades on about 6,000 operational A320 aircraft, affecting travellers in Australia and around the world.
The European plane-maker has instructed its clients to take "immediate precautionary action" following an evaluation of a JetBlue-operated A320 aircraft incident on 30 October.
In Australia, Tyrone Simes, the chief pilot for Jetstar, has confirmed the airline's flights are impacted and they expect "to see further disruptions today and probably minor disruptions tomorrow".
"The engineering team are able to change the software status of that computer on board the aeroplane, so they need to physically get on board and do that process," he said in a press conference at Melbourne Airport on Saturday, adding the process will take two to three hours.
"We've got about 90 flights affected. And of course that's just Jetstar. But it's important to note that it is a worldwide issue.

"Anything to do with the flight control system is a serious matter, and we take it very seriously," Simes said.
Jetstar planes 'ready to return'
On Saturday afternoon, a Jetstar spokesperson said the changes have already been implemented on some of their planes.
“As of 3:30pm, 20 of the 34 affected aircraft are ready to return to service. We’re expecting the remaining to be ready overnight, allowing flights to resume as planned on Sunday 30 November," they said in a statement.
"However, there may be some flow on delays or cancellations on Sunday as the network fully recovers. We will contact customers by SMS and email if there are any further disruptions.
"Safety is our number one priority, and we sincerely thank our customers for their patience and understanding as we worked through this issue."
SBS News understands Virgin Australia operates four A320s in its Virgin Australia Regional Airline business based in Western Australia, and the airline is able to cover the small number of flights that A320s were to have flown.
A Virgin Australia spokesperson has told SBS News that they "do not anticipate any impact to either Virgin Australia or our Regional Airline operations".
SBS News understands no Qantas-operated flights are affected by the recall.
Global flights impacted
The impacts are not only limited to Australia as Airlines from the United States to South America, Europe, India and New Zealand have warned the repairs could potentially cause flight delays or cancellations.
Air New Zealand has said that they are "affected by a global software issue impacting Airbus A320neo aircraft" and all of their "A320neo aircraft will be receiving a software update before operating their next passenger service."
"This will lead to disruption across a number of our A320neo flights today and we’re expecting a number of cancellations to services across that fleet," the airline posted on X.
There are around 11,300 A320-family jets in operation, including 6,440 of the core A320 model, which first flew in 1987. Four of the world's 10 biggest A320-family operators are major U.S. airlines: American Airlines, Delta Air Lines, JetBlue, and United Airlines.
The world's largest A320 operator, American Airlines, has said some 340 of its 480 A320 aircraft would need the fix. It said it mostly expected these to be completed by Saturday, with about two hours required for each plane.
ANA Holdings, Japan's biggest airline, has reported it cancelled 65 flights on Saturday after the Airbus A320 recall forced it to ground some aircraft.
Other airlines said they would take planes briefly out of service to carry out the repairs, including Germany's Lufthansa and India's IndiGo.
Britain's easyJet said it had already completed the work.
Colombian carrier Avianca said the recall affected more than 70 per cent of its fleet, around 100 jets, causing significant disruption over the next 10 days and prompting the airline to close ticket sales for travel dates through 8 December.
For about two-thirds of the affected jets, the recall will theoretically result in a brief grounding as airlines revert to a previous software version, industry sources have told Reuters.
What is the reason behind the recall?
The setback seems to be one of the biggest recalls in Airbus's 55-year history and follows weeks after the A320 overtook the Boeing 737 as the most-delivered model.
Airbus said in a statement that "intense solar radiation may corrupt data critical to the functioning of flight controls," adding that "a significant number of A320 Family aircraft currently in service" may be affected.
Replacing the software will take "a few hours" on most planes, but for some 1,000 aircraft, the process "will take weeks", a source close to the issue told the Agence France-Presse news agency.
The faulty software, the Elevator and Aileron Computer (ELAC), is made by aerospace and defence giant Thales.
"Airbus acknowledges these recommendations will lead to operational disruptions to passengers and customers," it said, apologising for the inconvenience.
The JetBlue incident
The major recall follows an incident involving a Jetblue-operated A320 aircraft on 30 October, which experienced an in-flight control problem caused by a computer malfunction.
The plane suddenly nosedived as it travelled between Cancun in Mexico and Newark in the United States, and pilots had to land in Tampa, Florida.
US media quoted local firefighters saying that some passengers were injured.
Produced since 1988, the A320 is the best-selling aircraft globally, with Airbus selling 12,257 of the plane by the end of September compared to the sale of 12,254 Boeing 737s.
