any updates on this?

I'm doing XXX-HKG-YYY (same ticket/same pnr/both legs CX), and the layover in hkg is 9 hours overnight. on both phone and whatsapp i'm trying to get an answer.

On WA they're clueless and can't even understand what i'm asking. Instead they state- you're not allowed to leave the airport, if you do, it's up to the airport discretion. ...? if i'm leaving the airport, i obviously am assuming i have the right to enter said country (i do), so this advice is just wrong. Then they stated that if i have a layover, and i try to do this, then i'd have to get rebooked, likely will be a fee. I don't think this is correct.

On the phone- they also couldn't comprehend what i'm trying to do. I suggest they call the HKIA check in desk (i don't have a number so can't call)- they said they can't do that.

So i'm just going to wing it. It's unfathomable to me that any airline would have an issue with this- what if i were at a long layover and went shopping outside of the airport, and came back with a new suitcase, they'd not honor it? =???
