Comments from a Virgin Australia Group spokesman:
Virgin Australia was one of many airlines globally to experience an outage with the Sabre booking system.
Sabre, which is a third-party IT system we use for check-in, boarding and flight bookings, is investigating the cause of the outage.
While it has since been resolved, the impacts on our guests were felt right across our domestic network, and on behalf of Virgin Australia, we apologise for any disruption caused.
We are working closely with Sabre to ensure that necessary measures are taken to prevent these outages from reoccurring.
