Jetstar passengers faced lengthy delays at a number of airports across Australia, as well as in New Zealand and Asia, on Tuesday after an IT outage downed check-in systems.

The budget airline acknowledged the problems in a tweet after 8am AEDT, though the first reports emerged just after 6am.
“Some flights are experiencing short delays this morning due to an IT outage affecting a few systems,” Jetstar said. “Our technicians are working on the issue.”
“We appreciate delays are frustrating and apologise to customers for the impact to their journey.”
By 11:30am, Jetstar said in a travel alert that airport systems were "progressively coming back online", with staff "working to resume normal operations as soon as possible".
iTnews has contacted the airline for further information on the issues.
Passengers have reported long delays at Melbourne, Brisbane, Adelaide, Gold Coast and Brisbane airports, with staff having to resort to manual check-in processes.

Jetstar flights out of overseas airports like Singapore and Queenstown also appear to have been affected.
The IT outage comes ahead of planned industrial action this coming Friday.
Australian airports also reported an outage of the global advanced passenger processing system for most of Tuesday, resulting in delays to outbound international passenger processing.
As at 2:43pm, Sydney Airport has advised that the system is back online.
The outage is the second to affect the Australian Border Force in the last week.
⚠️The international passenger check-in processing system is back online. Please continue to contact your airline for flight status. https://t.co/B4ro3BcfXK
