Say hello to Akureyri (BIAR). The airport with one of the most demanding approaches in the Europe. It will be included in Keflavik package at no additional cost as a present from us.
Runway 01 with 5.3° GS path, or runway 19 with 3.45° GS both with offset.
The runway length is 2400 m which allows you to go there with both turboprops and jets. Since Keflavik is known for its difficult weather conditions it may be a great alternate airport.
