Colombian carrier Avianca must perform software "downgrades" on roughly two dozen remaining Airbus A320-family aircraft as it works to fully resolve a vulnerability issue by 3 December.

Airbus is examining a newly discovered A320-family fuselage panel flaw that is delaying some deliveries, Reuters reports, adding pressure to its 2025 production push.

Europe's 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, threatening upheaval during the busiest travel weekend of the year in the United States and disruption worldwide.

JetBlue Airways has modestly reduced expectations for its year-end operational performance in response to a trio of disruptions - Hurricane Melissa, the US federal government shutdown and the global grounding of Airbus A320-family jets.

Dozens of airlines from Asia to the United States said they had carried out a snap software retrofit ordered by Airbus, and mandated by global regulators, after a vulnerability to solar flares emerged in a recent mid-air incident on a JetBlue A320.

A solar radiation–linked software flaw in Airbus A320 jets triggered urgent global fixes, causing possible delays but no safety risk for travelers.
