Best current option for LHR→SYD. LHR–SIN first leg uses Central Asian routing; SIN–SYD second leg is entirely clean. No advisory zone transit on either segment.
LHR–SIN first leg uses the Central Asian corridor — if Eurocontrol flow restrictions are active at departure, this leg is most exposed to delays. Plan extra buffer at Heathrow.
Evaluated using advisory airspace exposure, corridor sensitivity, detour impact, and hub routing logic — based on EASA and national authority advisories.
