It could take up to 20 years to build a new airport in Hvassahraun on the outskirts of Hafnafjörður, a suburb of Reykjavík, that would serve both international and domestic flights after. The cost of a new international and domestic airport could be a minimum of 300 billion krónur. This is stated in a report prepared for the Ministry of Transport and presented to the Environmental and Transport Committee of Parliament this morning.
