Cheap flights from Oslo
Cheap flights from Oslo start at two airports: Oslo Airport and Sandefjord, and the popular routes head east and south — Krakow, Warsaw, Gdansk, Katowice, Riga, Berlin, Bucharest, Chisinau, Paris and Barcelona. Norwegian, Ryanair, Scandinavian Airlines and Air Baltic do most of the heavy lifting, with Ethiopian Airlines and Mokulele Flight Service on a few connections. Whether you want a short hop to Poland or a longer run to Barcelona, the airport you leave from changes what you pay.

Airports — Oslo
Oslo departs from two airports, and they are not interchangeable. Oslo Airport is the main gateway, where the widest mix of carriers shows up — Scandinavian Airlines, Norwegian, Norwegian International, Air Baltic and Ethiopian Airlines all appear on departures. Sandefjord is the second option, smaller and worth checking side by side with the main airport before you commit to a fare, because the airline list and the timings differ. Decide which airport suits your trip first; it shapes your choice of carrier and how early you need to leave home.
When to go
Oslo flies all year, and the calendar sets the price. Summer is the busy stretch, when Norwegian school holidays send families to Poland, the Baltics and the Mediterranean, and fares on those routes firm up early. Easter and the winter break bring a second wave, and Christmas is its own thing. The calmer windows sit outside the peaks — late autumn, the weeks after the winter break, and midweek departures rather than Friday and Sunday. If your dates move, compare a Tuesday with a Friday before you book.
