Cached-fare history: across 5 months, Sep is the cheapest for MIA → LAS. Best time to be there: Mar–May · Oct–Nov.
Fares bottom out in September around $172 and peak in December near $492 — a $320 spread across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 6.5 hours outbound, on a 14-night trip — ticketed under Frontier Airlines, which on a connecting fare need not operate every leg. At $172 for 3,505 km each way, that works out to about $25 per 1,000 km flown. That is well under the $39 that medium-haul fares on this board typically run. Of the 5 departure cities we track at a similar distance from Las Vegas, this is the cheapest right now — 7% under the next one, New York.

How far in advance should I book MIA → 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We do not publish a number for this, because we cannot measure it yet.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 Miami to Las Vegas?
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.
