This Hong Kong connection avoids warning areas that affect some alternative routings on the London corridor. It ranks among the clearer options for this journey at the moment.
Sydney to Hong Kong (approximately 9h) is a clean, uncomplicated sector entirely south of any advisory zone.
Hong Kong to London second leg routes over Central Asia — standard European routing since the Russian airspace closure, but a heavily congested corridor slot.
Cathay Pacific has maintained consistent Sydney to Hong Kong to London service. Hong Kong hub has shown strong resilience through the post-2022 period.
Total journey is approximately 22 hours including transit — the longest of the three main corridor options, due to more northerly Hong Kong positioning.
This corridor makes most sense for travellers wanting to avoid all Gulf involvement, or connecting onward from Hong Kong to other East Asian points.
