A fault which saw several Jetstar airport check-ins go down this afternoon has been fixed.

Jetstar spokesman Phil Boeyen said a Telstra outage had affected computer check-in systems at a few airports - not including Auckland Airport - for about two hours this afternoon.

The fault was fixed and all systems were back online shortly after 5pm.

While it was down, Jetstar airport staff manually checked in travellers.

Boeyen understood the airline's mobile and online check-ins weren't affected.
