By plane
Oulu Airport (http://www.ilmailulaitos....) is the busiest in the country after Helsinki, and the Helsinki-Oulu sector is the country's most popular domestic flight with frequent services almost 20 flights per day each way on Finnair, Blue1 and Norwegian. A fully flexible return economy ticket might cost more than â¬200 but a non-changeable one-way ticket can go as low as â¬20 or a return ticket for less than â¬50 when bought months in advance. Norwegian is often cheapest, but airlines compete on price for this route so be sure to check others. There are also some services to Riga, Rovaniemi, Tampere, Turku and Kemi.
The terminal has recently been expanded and now has jet bridges to get you in the planes without having to walk in the freezing cold tarmac. The airport has an automatic map dispenser that provides free maps, but sometimes it doesn't work.
Bus 19 ~â¬5 connects the airport to the city center in 30 minutes. Buses operate quite frequently from 06:25 to about 21:00 on weekdays. After 21:00 buses operate infrequently to 01:30. A taxi will cost you around â¬30 for the same distance. Bus 19 also takes you to the University of Oulu (http://www.oulu.fi/english/).
