CX flight deck visits?

[Taildragger67]

Hi,

Just wondering what the rule is on CX re fright deck visits?

I know they're banned in most countries but there are still a few where they're allowed.

Is HK one?

Reason I ask is that I'm on 254 & 111 Thu/Fri & am wondering if it's worth asking when I get on.

Feel free to PM me.

Thanks
