Cathay lounge access during transit

[HockeyMonkey]

I am a OWE and have an upcoming transit which arrives in HKG at 7:30am via AY with a departure at 8pm via QF

Could I use the Pier or Wing first lounges as both an arrivals lounge in the morning for breakfast and a rest before clearing customs for a day trip into town and then reenter in the afternoon for dinner?

Theoretically you can but it is a hassle as you need to go back into airside area via transit security and then if you need to exit you need to go to airline desk and get permission to exit via transit security and then immigration.

I did it many years ago with dad.

As JohnK says this is easier said than done, and not encouraged. There is a plaza premium arrival lounge right under the train station. IIRC reasonably priced.
