The last notam I got said 40 minutes holding for traffic into Sydney. At 12:10 we were given a landing time of 13:29 local!This was on top of the 15 minute delay we copped on the ground in OOL. Then we were sequenced for the LLZ approach onto 34R where ATC stated 50% of the aircraft were getting in. We got in but the aircraft behind did not. Because we are operating to third worlds best practice if there is room for the extra fuel it gets carried. If its INTER I carry TEMPO if its TEMPO I carry ALT regardless of whether its above the SLAM but below the alternate. ATC, airline ops and the BoM are all operating in their own silos so my mitigator of that threat is to have more than enough liquid greenhouse gas to make up for the holes in the cheese.
