Düsseldorf Airport Check-In Outage Resolved After Morning IT Failure

The airport attributed the breakdown to an external data transmission fault used by airlines rather than a failure of its own systems.

Overview

  • IT provider SITA said connectivity issues affecting some check-in services were fixed, with all systems back to normal.
  • All airlines were affected to varying degrees, and several reverted to manual check-in and baggage drop during the disruption.
  • Morning passengers encountered longer queues and some missed flights, but the airport said only airlines can provide reliable figures.
  • Security checkpoints remained open and flight operations continued throughout, according to the airport.
  • Travelers were advised to confirm their flight status with their carriers and allow extra time as operations stabilize.
