As regards respect for the essence of the fundamental rights enshrined in Articles 7 and 8 of the Charter, it is true that PNR data may, in some circumstances, reveal very specific information on the private life of a person. However, in so far as, on the one hand, the nature of that information is limited to certain aspects of a person’s private life, concerning that person’s air travel in particular, and, on the other hand, the PNR Directive expressly prohibits in Article 13(4) thereof the processing of sensitive data within the meaning of Article 9(1) of the GDPR, the data covered by that directive do not by themselves allow for a full overview of the private life of a person. In addition, that directive, in Article 1(2) thereof read in conjunction with Article 3(8) and (9) thereof as well as Annex II thereto, circumscribes the purposes for which those data are to be processed. Lastly, that same directive, in Articles 4 to 15 thereof, lays down the rules governing the transfer, processing and retention of those data as well as the rules intended to ensure, inter alia, the security, confidentiality and integrity of those data, and to protect them against unlawful access and processing. In those circumstances, the interferences which the PNR Directive entails do not adversely affect the essence of the fundamental rights enshrined in Articles 7 and 8 of the Charter.
