Best for

Better structural resilience than the direct flight — the hub break at Istanbul creates a decision point. IST–NRT still uses the Central Asian corridor but you're not committed to it on a single ticket.

Weakness

Limited alternative paths if the main corridor is disrupted

Watch

IST–NRT traverses the Central Asian corridor — same exposure point as the direct flight, but you have a natural decision checkpoint at Istanbul.

Evaluated using advisory airspace exposure, corridor sensitivity, detour impact, and hub routing logic — based on EASA and national authority advisories.
