Fares bottom out in October around $231 and peak in April near $529, 129% dearer, across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 6.5 hours outbound, on a 3-night trip — ticketed under Frontier Airlines, which on a connecting fare need not operate every leg. At $268 for 3,505 km each way, that works out to about $38 per 1,000 km flown. That is below the $43 per 1,000 km typical of medium-haul fares here. Across the 5 departure cities we track at a similar distance from Las Vegas, this fare ranks 4th — 21% above the $221 from New York. The best time to be in Las Vegas: Mar–May · Oct–Nov.

Route facts
Good to know
Only slightly. The seasonal median is around $295 round-trip and this fare is 9% under it. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
Across 5 months of cached-fare history, Oct 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.
We do not publish a number for this, because we cannot measure it yet.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, Oct comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
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.
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.
