The diversion coordination is discussed in Section 1.10.1 of the report (pp.20-22). The aircraft had not declared it was in a "Mayday Fuel" situation at the time diversion coordination was initiated. Consequently, the coordination procedures were based on the normal movement of an arriving aircraft in a non-emergency situation, which can take 10-20 minutes. When the aircraft did eventually declare "Mayday Fuel", the diversion was immediately accepted and the aircraft given priority to land ahead of all other arrivals into Batam.
