Flights in and out of the UK are disrupted this month after a “software defect,” according to a report cited by multiple outlets. The fault leads to flight cancellations, affecting large numbers of passengers.

Both sources describe the disruption as significant, with flights being axed and passengers facing travel disruption. The reporting attributes the cause to a software problem rather than to weather or industrial action, but does not provide further technical details in the excerpts provided.

The outlets align on the overall picture: a system-related defect triggers widespread operational disruption across routes serving the UK. The sources differ mainly in presentation, with each focusing on the reported cause and the scale of passenger impact, rather than adding distinct information about remedial steps or the timeline of when the defect is identified and resolved.
