Whenever you're ready to visit, here's your guide to booking cheap flights to Las Vegas.


How to Find Cheap Las Vegas Flights

After major metropolitan hubs like New York, Los Angeles, or Washington, D.C., Las Vegas has among the most flight options of any airport in the country. And that's a recipe for cheap flights.

More than two dozen airlines fly in and out of Las Vegas (LAS) Harry Reid International airport, with direct flights to more than 100 cities in the U.S. and abroad. Budget airlines like Allegiant, Spirit, Frontier, and Sun Country are big players when it comes to flying to Las Vegas.

But it doesn't matter if you're not interested in flying a no-frills, ultra-low-cost carrier to Las Vegas. No matter what, that competition helps keep fares into the city low. How low? Well, we'll show you that soon.

Las Vegas may be a place unlike any other, but the rules governing how to find the cheapest flights still apply when it comes to flying to Sin City. Here's how you can be sure to snag a cheap fare:

  • Be flexible. All travelers would love to fly into Las Vegas on a Friday and return on a Sunday. Airlines know it, and they’ll typically jack up rates on those two travel days. If you can stretch it out into a long weekend or depart Vegas on Saturday instead, you'll not only get cheaper airfare – you may pay less for your hotel, too. 
  • Start your search with Google Flights, the most powerful search engine to find cheap fares, period. Google Flights will easily show you if you can score a much bigger deal by changing your dates by just a day or two.
  • Book directly with the airline using Google Flights rather than using OTAs like ExpediaUnless the savings of booking through those third-party sites are massive, it's not worth the trouble – you're much better off booking with the airline.
  • Always book your flights firstThe biggest mistake travelers make, whether they're going to Las Vegas or anywhere else in the world, is setting their dates, requesting their PTO, booking a hotel, and then turning to airfare. Maybe you'll get lucky and score a deal on the dates you need. But odds are you've just boxed yourself into paying a fortune.
  • Time it right by booking your airfare no sooner than six months before departure, but at least a month or so before your trip. That's the sweet spot for getting cheap flights to Las Vegas.
  • Avoid peak travel periods when high demand drives the cost of airfare sky-high. Flights around Christmas and New Years always tend to be expensive, but there's more to it than that. Late March and early April always seem to be expensive for flying to Las Vegas. And the convention and trade show circuit in Las Vegas can drive up prices too – especially during mega-events like CES in early January and the Specialty Equipment Market Association in early November each year.
  • Use flight deal alert services like our Thrifty Traveler Premium service, which sends the best Las Vegas flight deals from your home airport directly to your email inbox. We're constantly looking for cheap airfare within the U.S. and internationally.

  • Just did $83 RT non-stop DEN – LAS two weeks ago on Frontier. With my elite status (matched from IHG + $49), had no extra charges for carry-on, seat assignment, stretch seating or priority boarding. Great deal!
