The F/As to which Kremin refers are actually NZ-based
Qantas F/As.
Since early May QF longhaul aircraft no longer fly from Auckland to anywhere (ie LAX or SYD/BNE/MEL) so all the AKL-based crew (who are A330 and 747 rated only) have supposedly been offered transfers to Perth and other Oz bases but, in the interim, they have evidently been flying rosters which pax into OZ in order to operate QF longhaul services from Oz.
It doesn't sound a whole lot different to what J has done. The plot thickens?
