Airline passengers have been warned of potential travel disruption after Airbus identified a "significant number" A320 planes impacted by a software issue.
In a statement, the plane maker said: "Analysis of a recent event involving an A320 Family aircraft has revealed that intense solar radiation may corrupt data critical to the functioning of flight controls.
"Airbus has consequently identified a significant number of A320 Family aircraft currently in-service which may be impacted."
It is understood the incident that triggered an unexpected repair involved a JetBlue flight from Cancun, Mexico, to Newark, New Jersey, on 30 October, which suffered a sharp loss of altitude which injured several passengers.
An Airbus spokesperson told Sky News the necessary software change would affect up to 6,000 planes.
They added that for most of the affected aircraft, the required software update would take 2-3 hours. However, some aircrafts would need new hardware to be able to adopt the required software and that those aircraft would be affected for longer.
British Airways, Lufthansa and Wizz Air are all affected by the issue.
Airbus told Sky News that it had proactively asked the European Union Aviation Safety Agency (EASA) to issue an air worthiness directive for the affected aircraft.
The issue is affecting A319, A320 and the A321 models.
The UK Civil Aviation Authority said it is likely to mean some disruption and cancellation to flights.
Some airlines will be more affected than others, Colombian airline Avianca has announced that it will close ticket sales for 10 days due to the issue.
In a statement, easyJet said: "As we are expecting this to result in some disruption, we will inform customers directly about any changes to our flying programme tomorrow and will do all possible to minimise the impact."
American Airlines said the Airbus software issue would impact 340 aircraft and it expects some operational delays due to a major software change requirement.
The airline added that it expects the vast majority of the updates to be completed by "today or tomorrow", and that they are "intently focused" on limiting cancellations.
Wizz Air said some of its flights over the weekend may be affected, while Air India said the issue could lead to delays.
British Airways told Sky News that only three of its aircraft where affected and that the required fixes will be carried out overnight and are not expected to disrupt its operations.
