27.07 million passengers in 2025 — a record post-pandemic year, still 5% below the 2019 peak, with international traffic growing slower than at any other Scandinavian hub. Oslo’s airport is capacity-rich and competition-poor.
Oslo Airport handled 27.07 million passengers in 2025 (+2.4%), its best year since the pandemic but still 5.3% below the 2019 record of 28.59 million. International traffic (15.97 million) grew slower than at Copenhagen, Stockholm or any Scandinavian peer — Avinor itself flags the gap and calls for measures to defend Norway’s connectivity.
The structural drivers are domestic — the Oslo–Trondheim and Oslo–Bergen corridors remain among Europe’s busiest air routes — and outbound leisure to Spain and the Canary Islands. New carriers easyJet, Transavia and Volotea entered in 2025, adding competition on European leisure routes.
The airport sits 37 km north of the centre. Flytoget runs to Oslo S every 10 minutes in 19–22 minutes (NOK 252); the slower Vy service costs NOK 129. Coaches (Flybussen, every 20 minutes, ~NOK 259) serve 100+ stops but lose to the train on speed.
Capacity is the quiet story: OSL can handle 32 million passengers a year against 27 million actual — headroom most European capitals would trade for. The constraint is demand and long-haul network depth, not runways.
OSL is the mirror image of Athens: where ATH has demand leading capacity, Oslo has capacity waiting for demand. The international gap Avinor complains about is really a long-haul gap — the Gulf and Asian networks that Copenhagen built and Oslo did not. For travellers that is an opportunity, not a flaw: fares stay competitive, the Flytoget link is the best airport rail in the Nordics, and the weak krone prices the whole airport experience below its quality. Watch the long-haul route announcements in 2026 — they are the leading indicator for Oslo’s next hotel cycle.
