Cached-fare history: across 4 months, Mar is the cheapest for STO → WAS. Best time to be there: Apr–May · Sep–Oct.
Fares bottom out in March around $455 and peak in December near $570 — a $115 spread across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 10.5 hours outbound, on a 10-night trip — ticketed under SAS, which on a connecting fare need not operate every leg. At $455 for 6,636 km each way, that works out to about $34 per 1,000 km flown. That is below the $44 typical of long-haul fares here. Across the 20 departure cities we track at a similar distance from Washington, this fare ranks 2nd — 5% above the $432 from London. It is also the cheapest of the 22 routes of similar length we watch out of Stockholm.

STO → WAS, answered.
Is $455 a good price for Stockholm to Washington?
Only slightly. The seasonal median is around $535 round-trip and this fare is 15% under it, about $80. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from Stockholm to Washington?
Across 4 months of cached-fare history, Mar comes out cheapest on this route. The best months to actually be in Washington are Apr–May · Sep–Oct — when those overlap, that's your window.
How far in advance should I book STO → Washington?
We do not publish a number for this, because we cannot measure it yet.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, Mar comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Stockholm to Washington?
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.
