Thanks for the responses. I know the airport layout sometimes make a lounge visit on arrival impossible, but that's not the problem I encountered.

When you're physically passing the lounge on arrival and hold a boarding pass for the flight you arrived on, should be able to use it?
- According to the PP terms [MENTION=21736]mia[/MENTION] posted, apparently NO.
- In practice: YES sometimes, even when they scanned my boarding pass from an arriving flight.

That's confusing. I don't want to break the rules of PP, but if lounges admit entrance, it seems the rules allow so?
