This corridor avoids major conflict zones that affect some alternative paths to Tokyo. Hong Kong remains a functioning hub for this route, making it competitive among eastbound options from London.
Cathay Pacific routes London to Hong Kong via South Asia (southern corridor over India and South Asia), not through the Central Asian bottleneck — this is the key structural advantage over the Istanbul option.
Corridor dependency rated 1/3: multiple routing options exist for London to Hong Kong, versus the Istanbul option's sole dependency on Central Asian airspace.
Hong Kong hub is world-class in resilience. Tokyo is a stable destination. The Hong Kong to Tokyo segment over the Pacific approaches is uncongested.
Trade-off: Hong Kong sits south-southwest of Tokyo, meaning this routing approaches Tokyo from below rather than the northwest. Total distance is ~700km longer than Istanbul option.
Cathay Pacific's 2 daily London to Hong Kong departures give adequate but not high-frequency rebooking options if disruption occurs.
