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 flies Southwest nonstop and takes about 5.5 hours outbound, on a 4-night trip. At $290 for 2,642 km each way, that works out to about $55 per 1,000 km flown. That is above the $39 typical of medium-haul fares here. Across the 5 departure cities we track at a similar distance from Houston, this fare ranks 3rd — 1.9× the $155 we hold from 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.

The median cached fare across this calendar is 27% higher than when tracking began on Aug 8 — $288 then versus $367 now, across 5 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 $257, on Sep 23.
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.

SF → HOU, answered.
How far in advance should I book SF → 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We do not publish a number for this, because we cannot measure it yet.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 San Francisco to Houston?
Yes — the current board includes nonstop fares (Southwest). The outbound leg runs around 5.5 hours.
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.
