INCIDENT: Check-in Systems Offline for Days at Sunwing Airlines

Sunwing Airlines CEO, Mark Williams, revealed that the system the airline uses for check-ins and boarding was “breached” over the Easter long weekend. “A system that is up and running all the time, which never fails, was hacked,” Williams told CP24.

After 5 days, delays still occurring as service is restored. Williams told CP24 that due to the sensitive information that might have been breached, government agencies want to ensure that the breach has been remediated before resuming operations.

188 flights, thousands of passengers stuck and delayed when check-in systems taken offline, for 5+ days.

PAX reports the company targeted by the cyber attack was Illinois-based Airline Choice, which provides airline check-in and passenger security solutions.
