Best time to be in Oslo: Jun–Aug. Fare history for this route is still thin, so we make no seasonal call yet.
The cheapest itinerary we are tracking makes one stop and takes about 9.5 hours outbound, on a 6-night trip — ticketed under SAS, which on a connecting fare need not operate every leg. At $261 for 6,500 km each way, that works out to about $20 per 1,000 km flown. That is well under the $44 that long-haul fares on this board typically run. Of the 11 departure cities we track at a similar distance from Oslo, this is the cheapest right now — 8% under the next one, Abu Dhabi. It is also the cheapest of the 27 routes of similar length we watch out of Chicago. We have 2 months of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage.

CHI → OSL, answered.
How far in advance should I book CHI → 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We do not publish a number for this, because we cannot measure it yet.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. See /guides/what-moves-a-flight-price/ for the levers we can measure.
Are there nonstop flights from Chicago to Oslo?
The current cheapest fares involve a connection, ticketed under SAS. 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.
