Why book

Short, clean, very high-frequency route. Cathay Pacific and Korean carriers together provide 8+ daily departures. No advisory zone involvement.

The catch

Very few backup paths if this route is disrupted

Worth knowing

Hong Kong to Seoul avoids the warning area. No major warning area is shown in our current route data. Monitor typhoon disruptions July–October.
