Why book

Via Seoul adds a brief ICN connection but routes through the same Central Asian corridor. Good choice if direct NRT–FRA capacity is limited or if you benefit from ICN's transit infrastructure.

The catch

Goes close to a warning area but does not cross it

Worth knowing

ICN connection requires 1.5–2h transit minimum. Korean Air and Asiana ICN–FRA services are daily but less frequent than LH/NH combined — check availability on specific travel dates.

Comparable airspace profile to the direct option — both use the Central Asian corridor. Ranked slightly lower due to the additional connection, which adds schedule complexity without meaningful airspace benefit.

NRT–ICN first leg (~2h) is a clean intra-Northeast Asian sector with no advisory concerns.
ICN–FRA second leg uses the Central Asian corridor — same routing as the direct NRT–FRA option.
Korean Air and Asiana both operate ICN–FRA. This gives two-carrier rebooking flexibility at Seoul.
Seoul Incheon (ICN) is consistently rated among Asia's top transit hubs — efficient connections, strong infrastructure.
Total journey approximately 12 hours including transit at ICN. Slightly longer than direct but useful if NRT–FRA direct availability is tight.
