NJS/Cobham have been flying jets on all of these routes in some form or another for nearly 25 years. Before QANTAS domestic existed, before sunstate/eastern were bought by QANTAS. This is not new.
Don't spoil the story with facts.
I would be interested to hear how long the majority of these people complaining have been employed in the QF group, if they are there at all,
and secondly if QF purchased the QFlink side of Cobham (they could not afford the complete company) would the problem automatically be resolved and the pilots miraculously become of the same ability as the rest of the group?
