Route last assessed 6d ago

Best for

Best-rated option for FRA→NRT. Avoids Gulf entirely; ICN is a world-class hub with excellent onward frequency to Tokyo. The ICN→NRT second leg is only 2 hours — dramatically shorter than IST→NRT.

Weakness

Limited alternative paths if the main corridor is disrupted

Watch

FRA→ICN uses the Central Asian corridor — same exposure as the direct flight on the first leg. Check ATFM status before departure. ICN→NRT transits Korean/Japanese airspace: clean, uncongested, no advisories.
