Priority Pass terms and conditions:
Admittance to lounges is strictly subject to cardholders and any guests, if permitted, being in possession of a valid flight ticket and travel documents for the same day of travel. Airline, airport and other travel industry employees traveling on reduced-rate tickets may not be eligible for access. Outside the US, flight tickets must be accompanied by a valid boarding pass for a departing flight, i.e. outbound passengers only.
How or whether it is enforced at all will of course vary. If you have a document that looks like a boarding pass but without a seat assignment it's likely fine 99% of the time.
