Airbus calls for 'immediate' software upgrade to A320 aircraft

An American Airlines Airbus A320-211 is seen on the tarmac on Jan. 8, 2020 at Philadelphia International Airport (PHL).

A320 planes are flown by a number of domestic and international airlines, and the required software update could lead to "operational disruptions to passengers and customers," according to Airbus.
