This is subject to change based on future policy, but the way it works currently:
Before coming arriving in Iceland, you will need proof of a negative COVID result. You will supply this information at the airport when you are checking in for your flight. There’s also a registration document that you will need to fill out (it’s quite short) 24h before your flight. At the moment, you do not require a COVID test after landing, however that has been the case in other times. It’s impossible for us to gauge what policy will be like come May, but we’re committed to a safe event and will follow all policy that the Health Department puts out.
