In the European context, PNR for Customs is much bigger than PPR for the actual airport.
Any pilot who goes places for real needs to contact the airport beforehand - unless as I said the flight is to a known H24 or similar airport where you can definitely just turn up (H24 ones usually look at the incoming flight plans to see who is coming and advise Customs etc accordingly; an amazing intellectual feat which the smaller airports have not got their heads around yet).
