Bornholmslinjen
You can e.g. fly to Bornholm in just 35 minutes from Copenhagen or in about 1 hour and 10 minutes from Billund, Midtjylland, Aarhus, Aalborg and Sønderborg in Jutland, as well as from Stavanger and Stord in Norway (via Billund). Please note that some airports only have a direct connection to Bornholm during the summer.
