Destination briefWASWashingtonFree museums by the dozen, and three airports competing hard enough to keep transatlantic fares honest.Best windowApr–May · Sep–OctAirportsDulles (IAD) · Reagan National (DCA) · Baltimore (BWI)All routes into WashingtonWhen this route gets cheap.
Best time to be in Washington: Apr–May · Sep–Oct. 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 10 hours outbound, on a 7-night trip — ticketed under KLM, which on a connecting fare need not operate every leg. At $621 for 5,443 km each way, that works out to about $57 per 1,000 km flown. That is above the $39 typical of medium-haul fares here. Across the 15 departure cities we track at a similar distance from Washington, this fare ranks 6th — 44% above the $432 from London. That puts it in the cheaper half of the 10 routes of similar length we watch out of Dublin, where the middle fare is $621. We have 1 month 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.

DUB → WAS, answered.
How far in advance should I book DUB → 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We do not publish a number for this, because we cannot measure it yet.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. See /guides/what-moves-a-flight-price/ for the levers we can measure.
Are there nonstop flights from Dublin to Washington?
The current cheapest fares involve a connection, ticketed under KLM. 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 August 21). 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.
