안녕하세요. 대한항공 암스테르담 지점입니다.
4월 23일 "대한민국은 EU가 지정한 고위험 국가에서 제외"되었습니다.
따라서 한국에서 오시는 승객은 네덜란드 도착시 별도의 서류 작성이나, 격리는 필요하지 않습니다.

단, 참고로 스키폴 공항의 사이트에 언급된 "고위험국가에서 출발한 승객"은 별도 검역서류 작성해야 하지만, 격리 역시 '권고'하고 있습니다.
Update health declaration
Starting April 17th at 6 p.m, a health declaration is required for travellers from high-risk areas. Travellers from these areas are also urged to quarantine for two weeks. The European Union Aviation Safety Agency (EASA) maintains a list of airports in areas with a high risk of contamination. The measures above apply to passengers arriving in the Netherlands, which departed from airports in the mentioned countries and regions.

Travellers departing from these high-risk areas will receive a form from the airline they are travelling with. The questionnaire has been drawn up by the GGD and RIVM and must be completed before boarding. Travellers should keep the form with them during the trip. If one of the questions on the form is answered with "yes", the traveller will not be allowed on board by the airline.
