Maybe HKG doesn't claim to be a 24 hour airport, but I find it odd that most of the shops and eateries close by 11pm, before the late evening European and other departures. Have tried to get a drink or whatever before these flights only to find closed shutters or tills being counted.

My Citibank CC gets me free massages at a beauty place, but it closes by around 7pm and I rarely have a departure before then, can never use the privilege.

Last week arrived at a new time of day for me at HKG, 5:30am. Buses on required route not running till after 7am (no night bus either), and coffee shops not open till 7am so no chance of a caffeine boost. Sat there for an hour and a half like a lemon till bus service started.

Not major issues in an efficient airport I otherwise like, but I do wonder about the lack of amenities "out of hours". Maybe the J passengers are catered for in lounges and this is just a Y problem.
