Best time to be in Houston: Mar–May · Oct–Nov. 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 4.5 hours outbound, on a 3-night trip — ticketed under Frontier Airlines, which on a connecting fare need not operate every leg. At $158 for 1,961 km each way, that works out to about $40 per 1,000 km flown. That is about the $41 typical of short-haul fares here. Across the 6 departure cities we track at a similar distance from Houston, this fare ranks 3rd — 13% above the $140 from Chicago. It is also the 2nd cheapest of the 6 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.

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.

WAS → HOU, answered.
How far in advance should I book WAS → Houston?
We do not publish a number for this, because we cannot measure it yet.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 Houston?
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.
