I guess this will have a significant impact on short and medium-haul operations:
"Air France has received a communication from Airbus requesting airlines to carry out a software update on certain aircraft in the Airbus A320 family (A318, A319, A320, A321).
Air France strictly complies with the instructions of the authorities and the manufacturer and is forced to adapt its flight schedule operated by this type of aircraft."
(Source: AF website, 28 November 2025)

Background story: "Airbus said on Friday it was ordering immediate repairs to 6,000 of its widely-used A320 family of jets in a sweeping recall affecting more than half the global fleet" (Reuters)

Visible impact today: for example, all AF flights from TLS and NCE after 7pm were cancelled or heavily delayed.
