When this route gets cheap.
The cheapest itinerary we are tracking makes 2 stops and takes about 13.5 hours outbound, on a 6-night trip — ticketed under Southwest, which on a connecting fare need not operate every leg. At $421 for 7,772 km each way, that works out to about $27 per 1,000 km flown. That is well under the $44 per 1,000 km that long-haul fares on this board typically run. Across the 16 departure cities we track at a similar distance from Honolulu, this fare ranks 4th — 9% above the $388 from Dallas. It is also the 2nd cheapest of the 30 routes of similar length we watch out of Washington. 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. Fare history here is still too short to name a cheap season. The best time to be in Honolulu: Apr–Jun · Sep–Nov.

The median cached fare across this calendar is 2% higher than when tracking began on 8 Aug — $677 then versus $693 now, across 15 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 $310, on 10 Sep.
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.

Good to know
WAS → HNL, answered.
How far in advance should I book WAS → Honolulu?
We do not publish a number for this, because we cannot measure it yet.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. Our guide Why flight prices change covers the levers we can measure.
Are there nonstop flights from Washington to Honolulu?
The current cheapest fares involve a connection, ticketed under Southwest. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on 17 October). 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.
