well it depends on where you depart.. and whether it's a connecting flight
11 or 12 hours, I think.
It's about 7 hours to Dubai from HK and then 3 and a half hrs from Dubai to Larnaca Airport in Cyprus.
3hr 35min to 3hr 40min Hong Kong (HKG) to Phuket, Thailand (HKT) by a nonstop flight operated by Air New Zealand, Cathay Pacific Airways, Dragonair or Thai Airways.
it is 19 hours because you have to get on a fanny and hump it for 4 hours to get to hong kong ;)
