I might have a bad memory, but I thought in the past, Diamonds were able to guest 2 passengers with them, to the CX designated lounge for that flight. So for example, in JFK, the Diamond CX designated lounge is the "Soho" lounge. In the past I thought Diamond members could bring 2 guests with them as it is the official CX-utilised lounge.

It appears now that there is a distinction between CX operated lounges, and non-CX operated lounges. This Soho lounge specifically says that Diamond members can only bring 1 guest with them:

If you have a look at CX operated lounges, it points you to the general lounge admittance page which says Diamonds can bring 2 guests: https://www.cathaypacific.com/cx/en_...dmittance.html
There is no mention on this page of a distinction between different lounges.

The Diamond benefits page also says that passengers can only guest people travelling on the same flight: https://www.cathaypacific.com/cx/en_..._1655455297241
