- in terms of the number of data to be processed (it would now be easy to check whether, of the 34 types of PNR data, the ones that are really used are those relating to passenger identity - data which are already used by the Member States in connection with the directive for the control of illegal immigration).
- apstrādājamo datu apjoma ziņā (tagad būtu viegli pārbaudīt, vai no pasažieru datu reģistra 34 datu veidiem tiešām izmanto tos, kas attiecas uz pasažieru identitāti – datus, kurus jau lieto dalībvalstis saskaņā ar direktīvu par nelegālās imigrācijas kontroli).
