Cathay Pacific Asia Miles - Lounges in Jakarta

I'm flying CX CGK-HKG in Y 9am

I have Emerald status - which lounge would you recomend I use?

CX passengers usually have access to two lounges: Pura Indah Lounge and Premier Lounge. The Premier Lounge would have been a better choice but it was being renovated when I was at CGK two weeks ago. The Pura Indah Lounge is an awful lounge overcrowded with people accessing it with credit card status. It's better to hang around at the Starbucks IMO.

Renovations seemed to have finished when I was there on 6th Oct

Do Qantas or Japan Airlines have lounges? I'd be able to access both of these.

Neither has their own lounges (I think Garuda is the only airline that actually operates their own lounge at CGK - all the others seem to use contract lounges). Regardless, don't get your hopes up too high about the lounges at CGK - they beat being in the terminal, but The Wing they ain't :D.

Premier Lounge which is right across from the Esplanade lounge is very nice now after the renovation.

Esplanade Lounge is exclusively for SQ only and even the design is very much SKL.
