This is what happens when Pornstar goes U/S in a port where big brother doesn't fly to. When you take away that safety net it becomes apparent how budget this airline really is.
It has nothing to do with maintenance being contracted out to Qantas. If the truth be known a large part of Pornstars 320 work is done by people other than Jetstar.
Jetstar had a 330 problem a few weeks ago on the SYD-HNL route. The aircraft didn't even leave Sydney. But thats OK because big brother was able to pull them out of the poo by uploading quite a few pax on the QF HNL-SYD flight.
Quality is not a word that should be used anywhere when discussing Jetstar international.
