There's only one Jetstar.
It's res system is provided by Navitaire (called New Skies).
It's maintenance is proudly brought to you by the Jetstar Maintenance team currently headquartered in Newcastle.
As the A330 is - currently - considered an interim fleet, it was decided not financially/operationally expedient to train JQ's engineers to be A330 qualified. So a LOA was reached with QF Engineering to supply our engineering needs while that type is in our fleet.
No idea about Jetstar Asia - I'd assume it was the Singaporean engineering company.
No idea about Jetstar Pacific - I'd assume it was the Vietnam Airlines engineering company.
I'm pretty sure they use the Navitaire system for res as well.
I hope that's answered your queries.
