Finding Cheap Flights To Oslo

Oslo is served by Oslo Airport, Gardermoen (OSL), the main international airport and largest hub in Norway. It offers an extensive domestic network and comprehensive global connectivity from destinations across Europe, North America, Asia, and Africa. The city is also served by the smaller Oslo Airport, Torp (TRF), located farther south, which is a base for European low-cost carriers flying into the Oslo region.

Travelers flying into Oslo have access to a vast selection of direct arrivals. From OSL, key domestic routes include from Bergen (BGO), Stavanger (SVG), and Tromsø (TOS). International routes span major European capitals, long-haul arrivals from New York (JFK), Bangkok (BKK), and Dubai (DXB), and numerous leisure spots. From TRF, the focus is on low-cost European city break and sun destinations, with arrivals from London (STN), Edinburgh (EDI), and Mediterranean holiday airports.

The market for arrivals into Oslo is highly competitive. OSL is a hub for Scandinavian Airlines (SAS) and Norwegian Air Shuttle, and hosts all major international airlines flying into Oslo. Low-cost carriers like Ryanair and Wizz Air have a major base at TRF, creating intense price competition on many European arrival routes. This dual-airport system provides options for both full-service and budget travel into the Oslo area.

To secure cheap flights to Oslo, always compare prices into both OSL and TRF from your departure city. For European travel, book with Ryanair or Norwegian into TRF as early as possible. For domestic and intercontinental arrivals into OSL, compare SAS and Norwegian, and book well in advance. Be mindful of the significant distance (about 110km) between TRF and Oslo city center when calculating total travel time and cost — a cheap fare into TRF may still be worth it, but factor in the bus or train connection. Oslo's efficient public transport makes OSL easily accessible from the city for arriving passengers.
