Airport check-in chaos in Australia, New Zealand
Airline staff were forced to manually process customers after the globally-used, border-clearance system known as Advance Passenger Processing went down about 8am on Monday.
Photos uploaded to social media show queues snaking the length of airport foyers in Sydney and Melbourne, as staff worked to clear the backlog.
A Sydney Airport spokeswoman says its system came back on at 10.40am with check-in resuming "as normal". Melbourne's was again online by about 11am with all airlines able to process digital check-ins.
Brisbane Airport was also affected by the shutdown, prompting manual check-ins but no flights were delayed, a spokeswoman told AAP.
Six flights departing from Auckland Airport experienced minor delays when Immigration New Zealand's national system went "down" too, according to the airport's Twitter account.
"Immigration NZ advises the system is now fully functional. Customs arrivals Smartgate will be limited for flights ex Australia that departed during the outage," the New Zealand airport stated.
All airlines at Wellington Airport were able to process check-ins without delays once the "global" issue was amended.
Those flying internationally are advised to contact their airline to check the status of their service. ■
