Greece travel advice
Summary - As of 7 April 2019, the Hellenic Police will begin implementing systematic passport control checks for all European citizens travelling to/from destinations outside the Schengen area (including the UK). This is in line with the 2017 Schengen Borders Code regulation EU 2017/458, which will eventually be applied by all Schengen member states according to the individual timescales. Waiting times at passport control may be affected on departure from and arrival into Greece. You should ensure you arrive at the airport in good time.
