Perhaps Jetstar and the QF group are seeing what occurs when we don't have our own in house heavy maintenance capability. We can't get the work done ourselves so we have to pay whatever the 'market' dictates. Given the tight slots for maintenance around the world it appears that we now don't have much choice.
I was speaking to one of our former heavy maintenance guys last night (he was part of the OJH rescue in BKK) and he's alarmed at the lack of corporate memory now in QF with respect to either rescuing aircraft or even being able to maintain them if required!
