Please see this fine analysis of the new EU PNR Directive from a human rights perspective.
“According to the PNR (Passenger Name Record) Directive 2016/681 of 27 April 2016, a series of everyday data of all air passengers (third-country nationals but also EU citizens, including those on intra-Schengen flights) will soon be transferred to specialised units to be analysed in order to identify persons of interest in relation to terrorist offences and other serious crimes. This new instrument raises once again fundamental rights challenges posed by its future operation, particularly in relation to privacy and citizenship rights. Therefore, the story of the PNR Directive, as described below, is probably not finished as such concerns open up the possibility of a future involvement of the Court of Justice.”
