Buses 20 and 21 will take you between the centre of town and the university campus. In the morning, a 20 or 21 bus leaves the town centre every 5 to 10 minutes from the same bus stop, later in the day every 10 to 20 minutes. In the afternoons there is a 20 or 21 bus every 5 to 10 minutes from campus to town centre in the heaviest rush hour, later (after 1800) every 20 minutes.

Arriving at the Airport:
Taxi: Transportation from and to the airport generally is easiest by taxi. Both the hotels in the city centre and the university campus is a short taxi ride from the airport, 5–10 minutes except for rush hours. If you are going to the university, ask to be taken to “UiT – Hansine Hansens veg, The Faculty of Humanities/ or “ISV”). When you arrive there, just walk inside the nearest building - signs will lead you on.
Buses: There is an airport bus between the airport and the town centre; this has its final stop at the Scandic Ishavshotel. Look for buses named “Flybuss”.
If you arrive in the morning and want to go to the university campus, you have to look for buses marked with “UiT” (The University) and/or “Universitetssykehuset” or possibly “UNN” (the hospital close to the university). If in doubt, ask the driver! See separate itineraries for these buses at https://www.bussring.no/airport-express/.
