Viable LHR→NRT option, but the IST–NRT leg fully traverses the Central Asian corridor — the longest exposure to that congestion bottleneck of any option on this pair.
Limited alternative paths if the main corridor is disrupted
Check Eurocontrol Central Asian ATFM status before each leg. Delays on the IST–NRT segment of 45–90 minutes are not unusual during peak restriction periods.
Evaluated using advisory airspace exposure, corridor sensitivity, detour impact, and hub routing logic — based on EASA and national authority advisories.
