I have a trip coming up with 4-6 hour stopovers at the following airports: PEK, BKK, CGK and some shorter ones at SIN and NRT.

I am trying to figure out where/how to use some lounges for both me and my spouse. I have no elite levels with airlines, however I have 4 united club passes, amex plat (including priority pass), and the lounge club (2 free passes I believe).

Only NRT seems to have UA club, so I can use my UA passes there. I think I could probably use my priority pass to find a lounge anywhere, but I would have to pay $27 each time for my spouse. This is generally fine but with several stops, this could add up. Any help avoiding that fee would be appreciated.

I could also use info on which lounges (PP accessible) are best to use at those airports if anyone knows. Thanks.

Do not assume that you can use any lounge at an airport. In particular, at NRT the UA lounge is in Terminal 1 and reasonably close to most Star alliance gates but also walkable and accessible for DL, AF, and KE flights. You cannot use it for JAL, Qantas, AA, etc. flights.

You need to either provide more details or do some research. For example, the PP website usually has specific information on the location of their lounges.
