Overview

• Collins Aerospace, part of RTX, reported an electronic glitch in its MUSE software that affected electronic check-in and bag-drop, with airports reverting to manual processing.
• Heathrow said automated processing is returning and most flights are operating, as aviation data from Cirium showed delays there had become limited.
• Brussels Airport reported ongoing significant delays and some cancellations after the outage, following a request from Eurocontrol to cut half of flights during a specified window.
• Berlin Brandenburg continued manual procedures while working with Collins on fixes, reporting that delays had eased to a more moderate level.
• Germany’s BSI, the UK’s National Cyber Security Centre and the European Commission are engaged in the probe, and no official attribution has been made as Egypt noted delays on inbound flights to Cairo, Hurghada and Sphinx.
