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 6.5 hours outbound, on a 8-night trip — ticketed under Frontier Airlines, which on a connecting fare need not operate every leg. At $200 for 3,692 km each way, that works out to about $27 per 1,000 km flown. That is well under the $39 that medium-haul fares on this board typically run. Of the 3 departure cities we track at a similar distance from Washington, this is the cheapest right now — 28% under the next one, San Francisco. It is also the 3rd cheapest of the 7 routes of similar length we watch out of Los Angeles. 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.

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We do not publish a number for this, because we cannot measure it yet.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