SF → LAS, answered.
Is $87 a good price for San Francisco to Las Vegas?
Only slightly. The seasonal median is around $105 round-trip and this fare is 17% under it, about $18. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from San Francisco to Las Vegas?
Across 5 months of cached-fare history, Sep comes out cheapest on this route. The best months to actually be in Las Vegas are Mar–May · Oct–Nov — when those overlap, that's your window.
How far in advance should I book SF → Las Vegas?
We do not publish a number for this, because we cannot measure it yet.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 5 months of cached fares, Sep comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from San Francisco to Las Vegas?
Yes — the current board includes nonstop fares (Frontier Airlines). The outbound leg runs around 1.5 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.
