Are there any specifcs about the healh certifcate? This could be as simple as a predrafted letter provided by the Greek Government/Airline online that a doctor has to sign, saying that the patient had no symptoms within the last xx days. And what about non-tourism-related flights, those for business? I read a few weeks ago, Greece was thinking about allowing certain EU-citizens to fly into Athens from 15 May. Does anyone have an update on that? I understand that the Governments are still discussing these matters at EU level, considering bilateral agreements if an agreement fails at EU level.
