You forgot to mention how unreliable and how much manpower the A380 absorbs
I beg to differ. The worlds most avionic advanced passenger aircraft requires next to no avionic technicians these days (provided you dont mind the occassional 3 + hour delay). Manpower is really being saved there.
As for jacking incidents, who knows what happened there. And comparing overseas MRO's to SAM is like comparing apples to oranges. We don't have a heavy maint facility for this aircraft.
There are quality engineers all around the globe. Many in QF are from different backgrounds of maintenance, and from other countries too. What makes a real difference to maintaining a quality product are the facitlities, procedures and ratios of qualified supervision in place. IMHO Sydney had the best many years ago (but it wasn't "worlds best practice").
