Leadsled raises an interesting perspective.
The Asian route ex Australia to London was around 6 and a bit hours to WSSS.
Then circa 12 to EGLL.
Pushing the jetstream to YPPH, circa 5 hours and then 17 to EGLL, will passengers prefer the well trodden Asian route, or flock to fly trans continental to YPPH. Then a whole 17 hours to London?
