QNH1013,
Perhaps you are not those who cut the queue and I'm not saying all do that but it happens often enough to have caught my attention. Glad AAsia A320 is doing BKI and KCH most. come 1st Aug,there will be more relief on MH side.
Speed restriction for descend should be planned to all major airport. Most of them published this requirement in thier AIP.Chief pilot should have included this in SOP. Nevertheless, I agree with you that speed control/sequencing in KL FIR is an rather frustrating daily affair.
