Traveling from Denver to Las Vegas offers a journey from the Mile High City’s cool, crisp air to the warm, glittering lights of Sin City. Whether you’re heading to Las Vegas for a spontaneous weekend getaway, a business convention, or a leisurely vacation, finding the most affordable flights can make your trip even more enjoyable. In this blog, we’ll explore the best platforms and strategies for booking the cheapest flights from Denver to Las Vegas, using the resources available at CheapFlightsDeals.

1. Start with a Comprehensive Search

Utilizing Powerful Search Engines:

  • CheapFlightsDeals Search Tool: Begin your search with a comprehensive tool like CheapFlightsDeals which aggregates flight data from multiple airlines and booking platforms, ensuring you see a wide array of options.
  • Google Flights: Another excellent resource, Google Flights offers a user-friendly interface and immediate access to airline fares, allowing you to quickly compare prices for your specific travel dates.

2. Check Low-Cost Carriers Directly

Focusing on Budget Airlines:

  • Southwest Airlines: Known for offering competitive prices and two free checked bags, Southwest frequently has deals from Denver to Las Vegas. Note that Southwest’s fares don’t appear on most comparison sites, so you’ll need to check their website directly.
  • Frontier Airlines: As a Denver-based airline, Frontier often provides budget-friendly flights to Las Vegas. Keep an eye on their online deals and email subscriptions for promotional fares.

3. Consider Alternative Booking Sites

Exploring Different Platforms:

  • Skyscanner: This site is renowned for its ability to scour through countless travel sites and bring forward some of the cheapest options available, including hidden gems not found on more mainstream sites.
  • Kayak: With features like “hacker fares” which combine one-way tickets on different airlines to make a round trip, Kayak can help you find unique combinations that might save you money.

4. Timing Your Purchase Right

Knowing the Best Time to Book:

  • Book in Advance: Generally, booking your flight about six weeks in advance offers the best prices.
  • Best Day to Book: Studies suggest that booking on a Tuesday or Wednesday can often result in better rates, as airlines tend to release weekly sales early in the week.
  • Watch for Seasonal Deals: Las Vegas has several peak seasons, including New Year’s Eve and the summer months. Try to book outside these times, or if you must travel during these periods, book as early as possible.

5. Set Up Alerts

Staying Ahead with Technology:

  • Price Alerts: Both CheapFlightsDeals and other flight comparison tools offer features where you can set alerts for specific routes. This way, you’ll get notifications directly to your email or phone when prices drop for Denver to Las Vegas flights.

6. Utilize Rewards and Frequent Flier Programs

Leveraging Points for Flights:

  • Credit Card Points: If you have a credit card that accumulates travel points, check if you can redeem them for a flight from Denver to Las Vegas.
  • Airline Miles: If you frequently fly between these cities, consider sticking to one airline and accumulating miles, which can be redeemed for flights or upgrades.

7. Check for Package Deals

Combining Travel Components:

  • Flight Plus Hotel Packages: Sometimes booking a flight along with a hotel stay through sites like Expedia or Orbitz can provide savings compared to booking each separately.
  • Last-Minute Packages: If you’re flexible, last-minute packages can sometimes offer incredible value, especially in a destination like Las Vegas that caters to spontaneous travelers.

8. Follow Airlines on Social Media

Catching Exclusive Promotions:

  • Social Media Offers: Airlines sometimes announce flash sales exclusively on their social media platforms. By following airlines that operate the Denver to Las Vegas route, you can access these deals before they’re widely known.


Booking the cheapest flight from Denver to Las Vegas requires a mix of strategic planning and savvy use of online tools. By starting your search with robust platforms like Cheap Flights Deals, setting up price alerts, and exploring all possible options including direct airline promotions and package deals, you can ensure that you get the best possible deal on your airfare. Remember, flexibility and timing are key components in finding the lowest priced flights, so keep your travel dates as adaptable as possible and book when the time is right.
