Not really sure, but as a side note Perth SH is turning into quite a good little base from a flying prespective (clearly due to the reduction of the Perth LH base).
It has gone from a base where next to no trips were available to basically all trips for the month of July, mainly Japan and Singapore. Looking at the July bid book there are days where all their inter WA flights (which is all they use to do) are gone for Perth based crew and these have now been incorporated into longer trips for the eastern state bases.
Clearly this will not be financially viable long term as thats why the Perth base was opened in the first place but who knows the 29 LH crew start training on 1 July so they may see a return of their traditional flying in August.
Also no word yet on where regional progression will go, but if they were that short in Perth you would think they would be given start date's and Perth ASAP and they havent.
