• Brussels Airport said 25 departures were canceled Saturday and 50 on Sunday, and it asked airlines to cancel nearly half of Monday’s 276 scheduled departures as remediation continues.
• Heathrow reported most flights operating, though travelers faced longer check-in times, after earlier network measures reportedly led to substantial schedule reductions for a defined period.
• Berlin-Brandenburg advised use of alternative digital check-in options as staff continued manual processing, while some smaller airports reported brief impacts before reverting to their own systems.
