With backup systems and additional support mechanisms typically applied in such cases, are addressing the disruptions in air transport today caused by the problems mentioned by Microsoft.

For Greece, air traffic and passenger services continue without major issues, although sources in the sector told newmoney.gr that disruptions throughout the day are expected due to problems affecting airlines and airports abroad with their booking systems, which in turn impact flights to other countries. The issue caused by Microsoft’s systems reportedly does not involve air traffic control but mainly ground procedures such as check-in and security checks. Hence, backup systems have been activated for these checks, though delays are already being recorded on flights, especially since destination airports abroad (e.g., Berlin, Zurich) might be experiencing localized issues.

Aegean, the largest domestic airline, issued a statement: “As reflected in international media reports, problems with an antivirus system provider have created issues in air transport globally, without significantly impacting our operational function. However, due to the problems caused across the global chain and support systems, some services on our site have been affected, and our flights to and from affected airports may also be impacted. Our passengers can get updates from all official company channels.”

SKY Express flights are operating normally without its operational function being affected by the Microsoft blackout, according to the company’s announcement. “SKY Express informs its passengers that its flights are operating normally and its operational function has not been impacted,” the company stated.

Ryanair, the largest low-cost airline, advises all passengers to arrive at airports at least 3 hours before their scheduled departure time to handle any arising issues in time. Similarly, Wizz Air warns of disruptions across its network and requests passengers to arrive 3 hours early at airports.
