Great attitude. Slam and traffic hold has everything to do with it. ATC don't know and obviously don't care nor understand fuel policy. There was no traffic hold required after 0900 last night into BNE so why the delay or update of requirements. How is a pilot meant to second quess what atc are going to do when you are already airborne without prior knowledge with a finite amount of fuel. If you (ATC) anticipate there will be further TRAFFIC delays then promulgate a Notam to that effect don't use some local knowledge should know better crap. World's best practise not from our point of view. We all expect a few small delays speed reductions and vectoring but being told to hold for 15-20 minutes when there is no expectation and no advisory in place is poor management and especially when the weather is 3000m in rain. To hold out an olive branch we pilots and ATC need to see it from both sides and to look beyond our own backyards. End of rants. The PIC is ultimately responsible and for too long we have become compliant and without question.
