Nordic citizens do not need to carry a passport when travelling within the Nordic countries - with the exception of Svalbard and Iceland.
However, you should always be able to verify your identity upon request.
To travel in the EU and Schengen area, you must carry a valid passport or national ID that complies with EU 1157/2019.
Schengen countries:
Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Lithuania, Luxembourg, Malta, Monaco, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, and Switzerland.
Travelling within Schengen:
There are no individual security checks at the borders between Schengen countries. However, you still need to bring your national ID card or passport to prove your citizenship if necessary. In Latvia, Estonia and France, you must present a passport or national ID card when arriving and leaving.
The Schengen Agreement regulates free movement within the European member states, which means that there are no longer regular border controls. However, people travelling within the Schengen area (including children and infants) must always be able to prove their identity with a national ID card or passport.
Countries outside the Schengen area:
You must show your passport when checking in and boarding the plane when travelling to a country outside the Schengen area.
On Air Greenland’s and its partners’ flights between Denmark and countries outside the Schengen area, you must provide personal information including date of birth, citizenship, passport number, etc., when you check in.
United Kingdom:
If you are travelling to/from the UK or Ireland, your luggage must not weigh more than 32 kg. Baggage weighing more than this must be sent as air freight.
Only guide dogs and companion dogs are allowed in the cabin when travelling to/from the UK. Animals are not allowed in the cargo hold, but you can send your pet as air freight.
