When this route gets cheap.
Fares bottom out in December around $104 and peak in September near $1,793, 1624% dearer, across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 5 hours outbound, on a 2-night trip — ticketed under Frontier Airlines, which on a connecting fare need not operate every leg. At $188 for 1,961 km each way, that works out to about $48 per 1,000 km flown. That is above the $41 per 1,000 km typical of short-haul fares here. Across the 6 departure cities we track at a similar distance from Houston, this fare ranks 4th — 41% above the $133 from Los Angeles. It is also the 2nd cheapest of the 6 routes of similar length we watch out of Washington. The best time to be in Houston: Mar–May · Oct–Nov.

Good to know
WAS → HOU, answered.
Is $188 a good price for Washington to Houston?
Yes — the seasonal median for this route is around $320 round-trip. At $188 you're 41% below that, which we rate rare for this route.
What is the cheapest month to fly from Washington to Houston?
Across 4 months of cached-fare history, Dec comes out cheapest on this route. The best months to actually be in Houston are Mar–May · Oct–Nov — when those overlap, that's your window.
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We do not publish a number for this, because we cannot measure it yet.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. What we can measure is which month is cheap: across 4 months of cached fares, Dec comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Washington to Houston?
The current cheapest fares involve a connection, ticketed under Frontier Airlines. 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.
