Hi Ditzyboy,
My assumption is that PER SH flying will be 737's only. Not A330's. My understanding is based on an email the shortlisters with AO rec'd stating that the reason we can't start flying yet is because the next 767 from QF has been delayed until QF convert 7 A330's from SH cabins to LH cabins for LH operations.
So I think it will only be the one a/c type for PER in the future.
Hope this has helped.
Cheers
Raver
