Cheap flights from Oslo

Oslo Gardermoen Airport (OSL) is Scandinavia's second-busiest airport and the primary gateway for Norway, with a broad European network alongside transatlantic routes to New York and other North American cities. Norwegian Air, SAS, and Wideroe all operate from here, with low-cost competition keeping European fares notably competitive relative to Norway's otherwise high cost of living. Routes to Southern Europe — Spain, Italy, Greece — are among the most price-sensitive, with fares often 30-40% lower in shoulder months (April-May, September-October) compared to the Norwegian summer peak. November through February is when Oslo produces its sharpest prices to Southern Europe: demand from Norwegian holiday-makers falls away sharply and low-cost carriers cut prices to fill capacity — sub-€80 one-way fares to Spain and Italy appear reliably in those months. Oslo Gardermoen sits 50 km north of the city centre, reached by the Airport Express Train (Flytoget) in 22 minutes. For domestic Norwegian travel, OSL connects to Bergen, Stavanger, Trondheim, and over 40 regional airports in a network that makes flying the practical mode for most Norwegian intercity travel.
