When this route gets cheap.
The cheapest itinerary we are tracking flies Frontier Airlines nonstop and takes about 3 hours outbound, on a 1-night trip. At $104 for 1,902 km each way, that works out to about $27 per 1,000 km flown. That is well under the $41 per 1,000 km that short-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 — 26% under the next one, Miami. 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. Fare history here is still too short to name a cheap season. The best time to be in Washington: Apr–May · Sep–Oct.

The median cached fare across this calendar is 17% lower than when tracking began on 8 Aug — $221 then versus $183 now, across 19 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 $70, on 21 Oct.
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
DFW → WAS, answered.
How far in advance should I book DFW → 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We do not publish a number for this, because we cannot measure it yet.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. Our guide Why flight prices change covers the levers we can measure.
Are there nonstop flights from Dallas to Washington?
Yes — the current board includes nonstop fares (Frontier Airlines). The outbound leg runs around 3 hours.
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.
