I'm going to be in Kiruna, Sweden. I will arrive to the town late and I have a flight at 6 am. It does not make sense to me to book hotel for a couple of hours.
Are there specific hours when Kiruna airport is open or is it open 24/7?
I couldn't find a reference on the airport's own web site, but from this page
The terminal at Kiruna Airport is open during the day. The terminal opens about an hour before the first flight departure and close about 30 minutes after the last flight arrival. This means that the terminal is closed during the night. Kiruna Airport doesn’t offer any accommodation in direct connection with the airport.
