Can I use a Qantas Club single-entry invite card on Jetstar or Jetstar Asia?

[QF/JQ] PS QP invitation - use on JQ/3K? I was wondering if the single-entry invitation bestowed upon Silver members is useable when flying Jetstar or Jetstar Asia out of a port that has a Qantas-operated lounge (i.e. Singapore)?

Also, is it correct to understand that the Admirals Club 30 Day Membership grants access to Qantas-operated lounges as per Qantas Club membership (specifically in Singapore, Sydney, Brisbane and Canberra)?

Many thanks, and happy Christmas!

Yes you can use the single use pass as at any qantas club or international business lounge operated by QF when travelling on a QF or JQ flight number on your ticket. The policy does not mention 3K.  The 30 day AA pass can be used at any QF operated lounge.

Thanks. I believe QP members have access to the QP even flying on 3K Jetstar Asia, but I'd like to know if I could use a single-invitation pass in such a case. If the policy doesn't mention it, I'll have to see what others have found.

The AA pass cannot be used on Jetstar, right?
