Proposals in the EU Parliament calling for more information about airline passengers to be made available to national authorities are on the table; they would make the Passenger Name Record (PNR) of all passengers arriving and departing EU available. This record, which TSA uses in the U.S., includes passenger names and addresses, seat number, reservation info, itinerary, purchase method, etc.
While EU authorities have been generally very zealous about data privacy on many fronts, some believe this data would help spot potential terrorists before arrival. Details from Bloomberg News.
