Until the powers that be institute proper flow management, we at the UAE ACC will vector, speed control, hold for 10,15 or 20 mile trails as DXB require then you go over to 124.9 no speed control direct yada yada. Keep telling your bosses at Emirates/Arabia etc how much money it is costing them by having this bazaar (bizarre) mentality to DXB flow and maybe they will wake up and fix it.
As for DXB having holds, more power to them
