Global airlines affected by major Airbus A320 recall 

Europe's Airbus ordered immediate repairs to 6,000 of its widely used A320 jets in a sweeping recall affecting more than half the global fleet, threatening upheaval during the busiest travel weekend of the year in the U.S. and sparking disruption worldwide.

The fix mainly involves reverting to earlier software, but it must be done before the planes can fly again, according to a bulletin to airlines seen by Reuters news agency. Several airlines said the repairs could cause flight delays or cancellations.
