Same clean airspace as the Hong Kong option, but Seoul is a slightly lower-resilience hub for South Asian connections than Hong Kong. Ranks below Hong Kong on hub quality.
Singapore to Seoul routes north through South China Sea and Philippine Sea — no active advisory exposure.

Two carriers (KE, OZ) at Seoul provide carrier flexibility when rebooking if disruption occurs.
Incheon is a large, efficient hub with good connectivity across Northeast Asia.
