Cleanest airspace on both legs if Gulf avoidance is the priority. LHR–HKG via Central Asia; HKG–SYD clean southerly routing. Longest option but zero Gulf involvement.
Limited alternative paths if the main corridor is disrupted
LHR–HKG first leg runs through the most congested section of the Central Asian corridor. Eurocontrol flow restrictions affect outbound Heathrow capacity more frequently on this heading.
Evaluated using advisory airspace exposure, corridor sensitivity, detour impact, and hub routing logic — based on EASA and national authority advisories.
