Europe's Airbus has ordered immediate repairs for 6,000 of its widely used A320 jets, a sweeping recall impacting over half the global fleet and threatening significant upheaval during the busiest US travel weekend, alongside worldwide disruption.
The mandatory fix, primarily a reversion to earlier software, must be implemented before aircraft can fly again, according to a bulletin seen by Reuters. Several airlines anticipate these repairs could cause flight delays or cancellations.
The Civil Aviation Authority warned that those aircraft will have to have software modified “or remain on the ground from Sunday onwards until the software has been changed”.
In most cases, the update is expected to take two hours. But with tight scheduling for many aircraft, disruption is likely.
But Britain's three biggest A320 operators – British Airways, easyJet and Wizz Air – say their operations are unaffected.
Here are major disruptions flagged by airlines as Saturday morning in alphabetical order:

The Irish carrier said a limited number of aircraft were impacted.
