01Fare seasonality

When this route gets cheap.

Cached-fare history: across 4 months, Sep is the cheapest for CPH → OSL. Best time to be there: Jun–Aug.

Fares bottom out in September around $88 and peak in December near $129 — a $41 spread across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 2.5 hours outbound, on a 5-night trip — ticketed under AL, which on a connecting fare need not operate every leg.

The 6 days we hold a cached fare for

Tap a date → live search

The median cached fare across this calendar is 11% lower than when tracking began on Aug 8 — $123 then versus $110 now, across 5 recorded snapshots. This is a calendar-level trend, so an individual deal above can be lower. The lowest single day we have seen here is $92, on Nov 2.

These are the only days we have a cached price for on this route so far — not the only days it flies. The search above covers any date.

02Good to know

CPH → OSL, answered.

Is $88 a good price for Copenhagen to Oslo?

Yes — the seasonal median for this route is around $110 round-trip. At $88 you're 20% below that, saving about $22, which we rate good for this route.

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

Across 4 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 CPH → 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We do not publish a number for this, because we cannot measure it yet.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 4 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 Copenhagen to Oslo?

The current cheapest fares involve a connection, ticketed under AL. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.

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.
