When this route gets cheap.
Fares bottom out in November around $215 and peak in April near $463, 115% dearer, across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 5 hours outbound, on a 3-night trip — ticketed under Frontier Airlines, which on a connecting fare need not operate every leg. At $215 for 2,642 km each way, that works out to about $41 per 1,000 km flown. That is about the $43 per 1,000 km typical of medium-haul fares here. Across the 5 departure cities we track at a similar distance from Houston, this fare ranks 3rd — 1.6× the $133 we hold from Los Angeles. The best time to be in Houston: Mar–May · Oct–Nov.

Good to know
SF → HOU, answered.
Is $215 a good price for San Francisco to Houston?
Yes — the seasonal median for this route is around $300 round-trip. At $215 you're 28% below that, which we rate good for this route.
What is the cheapest month to fly from San Francisco to Houston?
Across 4 months of cached-fare history, Nov 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 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We do not publish a number for this, because we cannot measure it yet.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. What we can measure is which month is cheap: across 4 months of cached fares, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from San Francisco 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.
