The majority of the air traffic passengers pass through the capital region’s airport and there are good roads, trains and ferries linking the region to the rest of Norway and Continental Europe. The public transport network in the Oslo region comprises railway, metro and tramlines, buses and boats. The main goods terminals for road and rail are located in the northeast corridor. Together with the Port of Oslo they form the main core of goods distribution in Eastern Norway.

The main airport Oslo Airport Gardermoen (OSL) is located 45 km north of Oslo. OSL has been ranked the most efficient airport in Europe by the Air Transport Research Society (ATRS) for 2010, based on comparisons of how well each individual airport makes use of its production potential. 37 European airports were analysed.

Thanks to the Airport Express Train and a well-developed bus network, the Oslo Airport at Gardermoen is well connected to the rest of the Oslo region. The Airport Express Train spends 19 minutes from Oslo Airport at Gardermoen to Oslo Central Station. 

In addition to OSL, the Oslo region has two other international airports within close reach: Sandefjord Airport Torp, located south-west of Oslo and Moss Airport Rygge located in south-east of Oslo.
