Flights from Oslo to Helsinki

A real Duffel search for Oslo to Helsinki on 2026-10-01 found 100 offer(s), operated by Air Baltic Corporation A/S, Austrian, Finnair, Lufthansa, Norwegian Air Shuttle, Norwegian Air Sweden, SAS. Fares in this sample ranged from GBP 83.55 to GBP 239.51, with the cheapest at GBP 83.55 — a nonstop itinerary was available in this search. This is a dated snapshot from a single sample search (cabin: economy), not a live quote: always verify current fares and schedules directly with the airline or a booking platform before you travel.

The great-circle distance between Oslo and Helsinki is approximately 763 km; based on typical cruise speeds for a route of this length, the estimated flight time is around 1h 27m — an estimate, not a live schedule figure, since actual times vary with routing, winds, and the aircraft operated.

This snapshot reflects one departure date, one cabin, and one adult passenger searched via the Duffel flight-search API — a live search on your actual travel dates will typically surface more fare options and departure times than a single sample can capture, and fares generally move with demand, so the range above is a guide to what has recently been available rather than a promise of what you will pay. Nothing on this page is invented: every carrier and fare figure comes directly from the search described above, and a route with no confirmed offers is never shown as if it had one.
