How to Get Cheap Las Vegas Flights

Use Flexible Date Searches and Fare Alerts

Start with flexible-date tools such as Google Flights, Skyscanner, or Hopper. Set a price alert for your route and choose a date range of at least three days; shifting departure by one or two days often drops the fare noticeably. The cheapest windows to book domestic flights to Las Vegas are generally one to three months before departure, though error fares and flash sales can appear with little warning.

Consider Nearby Airports and Alternate Routes

Las Vegas McCarran (LAS) is the primary airport, but checking nearby alternatives like Henderson Executive (HND) or even flying into Phoenix (PHX) or Los Angeles (LAX) and driving or taking a bus can save substantial money. Budget carriers such as Frontier, Spirit, and Allegiant sometimes serve LAS from smaller regional airports with lower base fares, though added fees for bags and seats can erode the savings if you are not careful.

Compare Airlines and Fare Classes

Traditional carriers like Southwest, Delta, and United occasionally match ultra-low-cost prices, especially when you book a basic economy or economy fare and avoid extras. Use a comparison site that includes all carriers, then check the airline's own website — some carriers offer price matching or exclusive web discounts. Points and miles can also slash the cost, particularly if you have flexible travel dates and can book off-peak.

Avoid Common Booking Mistakes

• Waiting until the last minute, which usually raises prices on popular leisure routes.
• Booking only on the travel date you want; midweek departures and Tuesday or Wednesday flights are often cheaper.
• Ignoring baggage and seat fees, which can make a "cheap" ultra-low-cost flight more expensive than a bundled fare.
• Clearing cookies or using incognito mode is not reliably effective, but checking multiple devices and browsers can help confirm a price is genuine.

Time Your Trip for Lower Demand

Flying during shoulder seasons, midweek, and avoiding major conventions or holiday weekends typically yields the lowest fares. If your schedule allows, a Tuesday or Wednesday arrival and departure can be significantly cheaper than a Friday-Sunday trip. The exact savings depend on the time of year, your origin city, and how far in advance you book.
