Keg and others,
I can think of plenty of occasions when I and others both Captains and FO's have called fatigued without any reprurcssions either. As was pointed out earlier GS is not in a position to place sanctions on those that do.
But I am now going to respectfully leave this discussion because if it's just going to be a JQ versus QF pie fight:
A) I'm unqualified to engage the debate objectively because I've not seen both airlines from within.
B) From here on in I think it's just going to be character assassination and it serves nobody any purpose. I have a good life and I'm heading back to it.
