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.
