As of today, according to the official site of travel.gov.gr the Passenger Locator Form is optional. here's hoping the RAT/PCR Covid tests go to. I am having trouble finding test sites in central PA who will test in time for a Monday night flight (in May). There's always the airport test at $250 each.
Welcome to Greece!
From 15 March 2022 onwards, travellers visiting Greece are no longer required to fill out the Passenger Locator Form (PLF).
However, a simplified PLF remains in operation, the completion of which is OPTIONAL, for the sole purpose of enabling the traveller / family to issue an EU Certificate of negative or positive COVID-19 test result.
Travellers, who decide to fill out the simplified form, will receive the PLF with their unique Quick Response (QR) code via email (the QR code will be provided in a link in the email).
The PLF can also be found on the Visit Greece app and at travel.gov.gr. It is strongly recommended that all visitors download the Visit Greece app (GDPR compliant) for free, prior to their arrival in Greece.
