The London to Singapore routing via Hong Kong currently has no active disruption zones affecting the airspace. This corridor is clear for the moment, though you should verify current conditions with your airline and official sources before booking.
The catch
Very few backup paths if this route is disrupted
Worth knowing
Monitor conditions over Southeast Asia and the Indian Ocean before departure. Check for any new airspace notices in the days leading up to your flight.

This path avoids major warning areas in the region right now. Alternative routings eastbound from London often pass through busier or more monitored airspace zones, making this Hong Kong connection relatively straightforward on paper.
Both legs avoid the Middle East advisory zone entirely. London to Hong Kong routes east via Central Asia; Hong Kong to Singapore routes south through South China Sea — a fully Gulf-free journey.
The backtrack from Hong Kong to Singapore is real: Hong Kong lies ~2,600km north-northeast of Singapore, making this the longest total distance of the three options by ~1,400km.
Cathay Pacific's Hong Kong hub has strong resilience and excellent onward connectivity throughout Southeast Asia if Singapore connections are needed.
This option makes the most structural sense if Gulf risk is your primary concern and schedule flexibility allows for a 14-15 hour journey.
Cathay operates 2 daily London to Hong Kong departures with onward connections; rebooking depth is adequate but narrower than Emirates on the Dubai option.
