Best time to be in Lisbon: Mar–Jun · 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 11.5 hours outbound, on a 7-night trip — ticketed under Lufthansa, which on a connecting fare need not operate every leg. At $561 for 5,737 km each way, that works out to about $49 per 1,000 km flown. That is above the $39 typical of medium-haul fares here. Across the 8 departure cities we track at a similar distance from Lisbon, this fare ranks 6th — 1.7× the $326 we hold from Dubai. That puts it in the cheaper half of the 22 routes of similar length we watch out of Washington, where the middle fare is $634. We have 3 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.

WAS → LIS, answered.
How far in advance should I book WAS → Lisbon?
We do not publish a number for this, because we cannot measure it yet.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 Washington to Lisbon?
The current cheapest fares involve a connection, ticketed under Lufthansa. 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.
