Why book

Clean airspace on both legs. Sydney to Hong Kong is a major regional route; Hong Kong to Frankfurt uses the Central Asian corridor. Good choice if Singapore availability is limited.

The catch

Very few backup paths if this route is disrupted

Worth knowing

Hong Kong to Frankfurt runs through the most congested Central Asian corridor slot for Frankfurt-bound traffic. Eurocontrol flow restrictions affect this routing more frequently than Singapore-originating traffic.
