Why book

CGK–ICN via Hong Kong. Cathay Pacific provides the CGK–HKG leg; multiple carriers connect HKG–ICN. Avoids the warning area entirely — route over South China Sea and into Korea. Alternative when SIN routing is sold out or HKG schedules align better. Korean Air or Asiana connections from HKG are reliable.

Worth knowing

CGK–HKG–ICN avoids the warning area entirely. South China Sea is open and avoids the warning area. Monitor HKG connection time.
