Currently most reliable LHR→HKG option, but the IST–HKG leg depends heavily on the congested Central Asian corridor.

Weakness

Limited alternative paths if the main corridor is disrupted

Watch

Check Eurocontrol Central Asian flow restriction status within 24 hours of departure for the IST–HKG leg. Flow restrictions on this segment cause delays of 30–90 minutes.
