Best time to be in Brussels: Apr–Jun · Sep. 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 3.5 hours outbound, on a 2-night trip — ticketed under Ryanair UK, which on a connecting fare need not operate every leg. At $146 for 1,085 km each way, that works out to about $67 per 1,000 km flown. That is above the $41 typical of short-haul fares here. Across the 6 departure cities we track at a similar distance from Brussels, this fare ranks 6th — 3.8× the $38 we hold from Stockholm. That puts it in the cheaper half of the 8 routes of similar length we watch out of Oslo, where the middle fare is $151. 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.

The median cached fare across this calendar is 7% higher than when tracking began on Aug 8 — $168 then versus $180 now, across 6 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 $122, on Sep 15.
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.

OSL → BRU, answered.
How far in advance should I book OSL → Brussels?
We do not publish a number for this, because we cannot measure it yet.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 Oslo to Brussels?
The current cheapest fares involve a connection, ticketed under Ryanair UK. 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.
