Oslo is expensive Norway, but Norwegian keeps Europe cheap and Norse opens up the US — and the single best money move is taking the Vy train, not the Flytoget express, into town.
Oslo Gardermoen (OSL) is Norway’s main gateway, where Norwegian (the home low-cost carrier) and SAS set the European map, Norse Atlantic opens up low-cost long-haul to the US, and Wizz Air backfills the budget eastern routes. Norway is a pricey country, so timing and carrier choice matter more here than almost anywhere — but the cheap fares are genuinely there if you fly the right months.
The fares below are real prices aifly has tracked leaving OSL, cheapest first. Oslo’s strengths are the Maghreb (Fes, Essaouira, Marrakech, Casablanca), the Caucasus (Armenia, Azerbaijan, Kutaisi, Georgia), Turkey, Cape Verde, and a strong North American bench (New York, Washington, San Francisco, Minneapolis, Seattle). Learn the season, set an alert, and book to the target.
When fares from Oslo actually drop
The cheapest windows are November and the broader winter outside the holidays, plus the April–May shoulder before the brief, intense Norwegian summer. June and July are the expensive months — peak season in both directions, when Norwegians travel and visitors flock north — so they’re the worst time for value. On the transatlantic routes, the US is cheapest in the late-autumn and winter shoulder.
Lead time beats day-of-week. Norwegian and Wizz short-haul fares price best 4–8 weeks out and reward jumping on the seat sales; Norse and SAS long-haul to the US rewards booking 2–3 months ahead with a fare alert. For a flexible trip, simply avoiding June–July does most of the work.
Which airlines keep Oslo cheap
Norwegian is the home team and the floor-setter on European and southern-sun routes — but read its fares: LowFare includes only a cabin bag, while LowFare+ adds a 20 kg checked bag and a seat, and the gap is often worth it. SAS covers the network routes, and Wizz Air competes on the eastern and Maghreb map.
The standout for value long-haul is Norse Atlantic, the Oslo-born low-cost carrier flying nonstop to the US East Coast and beyond, routinely undercutting the legacy fares. On the routes Norse doesn’t fly, the Gulf carriers (Emirates, Qatar, Turkish) and SAS connect via their hubs, usually with a bag. Bag math: Norwegian LowFare, Wizz and Norse’s cheapest fare all exclude a checked bag — price it in before comparing, especially on a long US trip.
Getting to and from Oslo Gardermoen (OSL)
This is the saving nobody tells you about. Two trains run the 50 km from Gardermoen into Oslo, and they’re nearly identical in time but not in price. The famous Flytoget express costs about 258 NOK (~€22) for a 19-minute run. The Vy regional train does the same trip in about 23 minutes for roughly 129 NOK (~€11) — literally half the price for four extra minutes. Unless you’re chasing those minutes, take the Vy.
Both run frequently to Oslo Central Station (Oslo S). A taxi is eye-watering by any standard (700+ NOK), so the train is the only sane choice. OSL is a clean, efficient single-terminal airport — easy to navigate, with both train platforms directly below arrivals.
