Airlines across the world raced to keep their fleet operating after a major software glitch forced an urgent update for Airbus SE’s most widely flown aircraft, with the rapid response avoiding a major meltdown during a crucial holiday-travel season.

Airlines around the world are racing to avoid widespread cancelations by fixing thousands of aircraft which need immediate maintenance to protect from a problem that injured passengers and caused an emergency landing last month.

Transportation Secretary Duffy says minimal travel disruptions expected as airlines rush to complete Airbus A320 software updates by Sunday.

The recall followed an unintended loss of altitude on an October JetBlue flight from Cancún to New Jersey which injured 10 passengers.

The setback appears to be among the largest recalls affecting Airbus in its 55-year history and comes weeks after the A320 overtook the Boeing 737 as the most-delivered model. At the time Airbus issued its bulletin to the plane's more than 350 operators, some 3,000 A320-family jets were in the air.

One of the world’s largest airplane makers said Friday that intense solar radiation may corrupt data critical to flight controls on a “significant number” of its most popular aircraft, prompting a swift response from several airlines. Airbus attributed the revelation to a recent analysis involving its A320 family of aircraft.

Thousands of Airbus planes are returning to normal service after being briefly grounded following a warning that solar radiation could interfere with onboard computers.

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.

A Jetblue flight last month had an issue that led to several injuries. That's what led to an investigation and possible grounding.
