Passengers have described "chaos" at a UK airport during check-in procedures following a worldwide IT failure on what would typically be one of the busiest days for flying since the pandemic's outbreak inception. Additionally, train services across several countries also experienced disruptions due to similar technical problems.
Over 1,000 flights globally were affected as Microsoft-developed Windows systems employed by airlines and airports encountered issues. Some US carriers like American Airlines and Delta made the decision to ground all their flights temporarily until the problem was resolved. The Dutch carrier KLM reported difficulty in handling flight operations, leading to a significant reduction of its services that morning. Similar occurrences were observed in India, Japan, and Australia as well.
In the UK, notable airports such as London Gatwick and Luton faced challenges with their check-in systems. The nation's primary commuter railway service, GTR, had to reduce its train services due to communication system outages. A passenger at Gatwick described a situation where he spent over three hours waiting in line for the check-in process during what was expected to be one of the hottest days so far that year.
Airline operators like Ryanair and easyJet stated they were not responsible for these problems, advising passengers to arrive at airports earlier than usual. Wizz Air noted issues with its website, online check-in services, and apps prompting a switch to manual check-ins. British Airways acknowledged that their operations might experience disruptions due to the IT system outages.
At Luton airport in the UK, long lines were reported by passengers while Heathrow mentioned minor impacts on its systems but reassured minimal effects on flight schedules thanks to contingency plans. At Palma de Mallorca's airport, a family of five experienced substantial delays due to technical issues and extended waiting times.
The Business Travel Association pointed out that the IT problems were having significant implications for global travel, with travel management companies working diligently to find solutions and reassure affected passengers worldwide. Cirium's statistics showed 1,390 flights cancelled by 11 am UK time on Friday - typically a busy day in terms of departures since the pandemic began.
The UK air traffic control organization Nats confirmed that its systems were fully operational despite having faced IT issues last summer. The National Rail reported widespread IT challenges across their network, causing potential train cancellations and disruptions to customer information services. A spokesperson for the Rail Delivery Group expressed regret over any inconvenience caused to passengers and assured that most trains were still running.
Several train service operators reported issues with ticket vending machines due to IT problems, including South Western Railway. Despite these challenges, Network Rail, responsible for railway infrastructure, remained unaffected by the outage.
