Thousands of flights have been disrupted worldwide after planes were grounded by a software problem. As many as 6,000 Airbus planes may have been affected by the error, resulting in cancellations on a number of UK airlines, including Wizz Air, EasyJet and Jet2.

Meanwhile in the USA, American Airlines has seen more than 300 planes grounded over the Thanksgiving period when six million travel home to be with their families.

It is believed the problem was discovered after an incident in October when a flight from Cancun, Mexico, to Newark in New Jersey suffered a sharp loss of altitude. The JetBlue plane dropped 100 ft in just seven seconds, leaving 15 people injured including children. It had to carry out an emergency landing in Florida.
