As of April 7th, 2019, the Hellenic Police has implemented EU Regulation 2017/458 which requires for all European citizens, travelling to/from Non-Schengen destinations, systematic checks against relevant databases.
In view of the above, increased waiting times might be expected at passport control, thus passengers travelling to Non-Schengen destinations are kindly requested:
to timely attend the checkpoints of the Hellenic Police, allowing sufficient time to reach the Departure Gate of their flight.
to hold a passport document rather than an id card, in order to accelerate the checks.
Passengers travelling to domestic destinations or to International destinations within the Schengen Treaty do not fall in this Regulatory framework. The following countries are member states of the Schengen Treaty:
Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxemburg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
