In early December, the E.U. Commission—Europe’s governing body in Brussels—issued a directive requiring the 28 countries to share the Passenger Name Record, or PNR, of those traveling around Europe, and to retain passenger information—a proposal E.U. officials had mulled since 2011. After the Paris attacks, officials said PNR sharing was a key measure in safeguarding airplanes and trains against terrorism. Nearly four months later, the idea is no closer to reality, however. Europe’s Court for Human Rights has ruled that the measure would violate passengers’ privacy, while several countries have voiced similar concerns.

“There are delays, and it has not been voted on,” St-Pierre says. “The delays are both the court order, and politics.”
