01Fare seasonality

When this route gets cheap.

Cached-fare history: across 5 months, Sep is the cheapest for LON → OSL. Best time to be there: Jun–Aug.

Fares bottom out in September around $41 and peak in February near $91 — a $50 spread across the 5 months we track. The cheapest itinerary we are tracking flies Ryanair UK nonstop and takes about 2 hours outbound, on a 7-night trip. At $41 for 1,154 km each way, that works out to about $18 per 1,000 km flown. That is well under the $41 that short-haul fares on this board typically run. Of the 9 departure cities we track at a similar distance from Oslo, this is the cheapest right now — 52% under the next one, Paris. That puts it in the cheaper half of the 12 routes of similar length we watch out of London, where the middle fare is $53.

02Good to know

LON → OSL, answered.

Is $41 a good price for London to Oslo?

Yes — the seasonal median for this route is around $55 round-trip. At $41 you're 25% below that, saving about $14, which we rate good for this route.

What is the cheapest month to fly from London to Oslo?

Across 5 months of cached-fare history, Sep comes out cheapest on this route. The best months to actually be in Oslo are Jun–Aug — when those overlap, that's your window.

How far in advance should I book LON → Oslo?

We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 5 months of cached fares, Sep comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.

Are there nonstop flights from London to Oslo?

Yes — the current board includes nonstop fares (Ryanair UK). The outbound leg runs around 2 hours.

Are these prices guaranteed?

No — these are cached fares found on real searches (this one on September 1). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
