IT Failure Disrupts Check-In at Düsseldorf Airport, Systems Restored by Midday

A connectivity breakdown at Sita cut external data links used by airlines for processing.

Overview

  • An early morning outage slowed check-in and self-bag-drop, causing long queues at Düsseldorf Airport.
  • All carriers were affected to varying degrees, and several resorted to manual processing at counters.
  • Sita reported normal operations resuming around 12:40 p.m. local time, with the airport confirming recovery shortly after.
  • The airport’s own systems were unaffected, security checkpoints stayed open, and flight operations continued.
  • Some passengers missed departures due to delays, and the airport advised travelers to check status directly with their airlines.
