Passengers from these airports are tested on arrival. Anyone who tests negative for the coronavirus must be self-quarantined for a week. Those who test positive must be quarantined for two weeks under supervision. Other passengers are only examined by sampling.
Groningen Airport Eelde
Groningen Airport Eelde is not on the list. The north of the Netherlands is much less hard hit by the virus. In theory, tourists can fly from there to Greece so as not to have to be quarantined, but the problem is that there are no flights (yet).
As of June 15, Greece will only open the airports of Athens and Thessaloniki to foreign tourists. Groningen Airport has no scheduled services to those cities. Dutch (and Belgians) could fly from German airports, for example, so as not to have to be quarantined.
The policy outlined above applies in any case from 15 to 30 June. The quarantine obligation is intended to expire from 1 July, when all Greek airports will open up again to foreign tourists. But the government has the caveat that this can still change.
First, Greece did not yet want to welcome tourists from the Netherlands, Belgium and a number of other countries from June 15. But the European Commission strongly criticized this: there should be no discrimination on nationality. Greece then “clarified” the policy.
