WOOKiee.......your correct on a few accounts, however what you are dealing with are people who dont reason very well. For whatever reason, they find comfort in being negative about V Australia and tend to troll pprune in search of a negative post about the company.
It makes me think they were either knocked back for an interview or failed one, or are a bit envious of mates of theirs that may be flying B777's and they arent. Why else would they concern themselves with the operation? there is absolutely d!ckall they can do to improve conditions, and sledging V Australia pilots and the operation itself, I think is a futile attempt at making themselves feel better.
But hey....they are experts though...some of them fly for REX and are champions at taking on the Singaporeans, so they are obviously well versed to offer us all advice on what T&C's to accept and are great at telling other pilots "I told you so"..
