My father and I are flying CX F in a couple of months on different flights. I am on CX 873 arriving at 6:10 AM while he is on CX 881 arriving at 6:45 AM. We're connecting later that afternoon to BKK

Where would be the ideal place in HKG Airport for us to meet up before heading into the city for a bit? I was thinking the Arrivals Lounge but perhaps a different lounge or location would be easier and more comfortable to meet and freshen up before going into town?

Thank you!
