Go to the airports early if they have time cause both Hong Kong and Singapore Int’l Airports have wonderful/spacious shopping arcades where you can roam/window-shop/shop around, and enjoy a vast variety of Asian and western cuisines!

CX Flight number but the carrier is LCC Hong Kong Express which means no meal and no drinks at all without paying. Not even water. So keep your credit card handy so you can buy a drink if you get thirsty. Seating is LCC cramped and basic. No IFE. Gate was the furthest possible gate in the satellite terminal at HKIA so allow time to walk there.

signage could be better in locating transfer departure gate when you are coming off of a transiting flight. Airport has lots of amenities
