Cheap Flights Denver to Vegas? Insider Insights for Smart Travelers
The Denver to Las Vegas route is one of America’s most traveled corridors, connecting Colorado’s vibrant capital with the glittering entertainment oasis of the Southwest. Whether you’re chasing weekend getaways, attending conventions, or planning a quick escape from the Mile High City, finding affordable airfare on this route requires strategy, timing, and insider knowledge. This comprehensive guide reveals proven tactics to secure the cheapest flights from Denver to Las Vegas while maximizing your travel value.
Las Vegas remains one of the most accessible destinations from Denver, with multiple daily flights and competitive pricing between major carriers. The approximately 600-mile distance and one-hour flight time make this route incredibly convenient, but that convenience can come with premium pricing if you don’t know when and how to book. Understanding seasonal patterns, airline strategies, and booking windows can save you hundreds of dollars on your journey.
Best Times to Book Flights Denver to Las Vegas
Timing is everything when hunting for cheap flights from Denver to Las Vegas. Industry data consistently shows that booking 1-3 months in advance typically yields the best prices for this route. However, the Denver-Vegas corridor has unique characteristics that differ from longer-haul flights, making it essential to understand local travel patterns.
Tuesday and Wednesday departures historically offer the lowest fares on this route, as business travelers dominate Monday and Friday flights. If you have flexibility, avoiding peak travel days can reduce your ticket price by 20-40%. Early morning departures (6-8 AM) often cost less than afternoon or evening flights, though you’ll sacrifice sleep for savings.
The sweet spot for booking appears to be 4-6 weeks before your intended travel date. At this window, airlines have released most of their inventory but haven’t yet implemented surge pricing for last-minute bookings. For weekend trips, consider flying out on Thursday evening and returning Sunday afternoon rather than the traditional Friday-Sunday schedule.
Flash sales and error fares occasionally appear on this route, particularly when airlines engage in price wars. Following travel blogs and deal aggregators can help you catch these rare opportunities. Set up price alerts on multiple booking platforms to monitor fluctuations in real-time.
Airline Options and Price Comparison
Denver International Airport serves as a major Southwest Airlines hub, which significantly impacts pricing on the Denver-Vegas route. Southwest’s checked bag policy and frequent promotions often make it competitive despite appearing higher at first glance. United Airlines, Delta, and Frontier also operate this route regularly, each with distinct pricing strategies.
Southwest Airlines dominates the Denver-Vegas market with the most daily flights, typically 15-20 departures daily. Their transparent pricing (bags fly free) sometimes makes their fares more economical than competitors charging hidden baggage fees. Southwest also offers same-day flight changes at no additional cost, providing flexibility for budget-conscious travelers.
Frontier Airlines frequently offers the lowest base fares on this route, though their strict carry-on policies and baggage charges can negate savings. If you’re traveling light with only a personal item, Frontier can deliver genuine bargains. Delta and United typically position themselves in the mid-range, occasionally matching Frontier’s prices during competitive periods.
For those concerned about flight reliability and safety, understanding airline safety records and operational history helps balance price with peace of mind. While all commercial carriers maintain rigorous safety standards, some travelers prefer established carriers with extensive operational networks.
Money-Saving Strategies for Budget Travelers
Beyond basic booking strategies, several proven tactics can dramatically reduce your Denver to Las Vegas airfare costs. The most effective approach combines multiple strategies rather than relying on a single method.
Use Flight Comparison Tools Strategically: Kayak, Google Flights, and Skyscanner provide price tracking and comparison capabilities across multiple airlines simultaneously. However, these tools sometimes miss budget carrier deals or special promotions. Cross-reference results with direct airline websites, as some carriers offer exclusive discounts unavailable through third-party platforms.
Embrace Flexible Travel Dates: Using flexible date search features reveals price variations across weeks. A Tuesday flight might cost $89 while Friday costs $159 for the identical route. Even shifting your trip by 2-3 days can yield substantial savings. This flexibility is particularly valuable for remote workers and retirees without fixed schedules.
Clear Your Browser Cookies: While airline price discrimination based on browsing history is debated, clearing cookies before booking ensures you’re not shown inflated prices based on previous searches. Use private browsing mode or clear your cache before finalizing purchases.
Consider Connecting Flights: Occasionally, one-stop itineraries cost significantly less than direct flights, particularly when connections route through major hubs. While this adds travel time, savings of $50-100+ might justify the extra hour in the air for budget-conscious travelers.
Join Airline Newsletters: Southwest, United, Delta, and Frontier regularly email exclusive deals to subscribers. These promotions often provide 15-25% discounts on specific routes, and the Denver-Vegas corridor frequently appears in promotional rotations.
Seasonal Pricing Patterns Explained
Las Vegas experiences dramatic seasonal variations in tourism, directly impacting flight prices from Denver. Understanding these patterns allows strategic planning around low-demand periods.
January and February: Post-holiday travel slumps create some of the year’s lowest fares. Winter weather in Denver discourages casual travelers, and Las Vegas’s winter season lacks the appeal of summer pool parties or holiday festivities. Expect fares in the $79-120 range for round-trips.
March through May: Spring break and warm weather increase demand moderately. Prices rise to $99-150, with significant spikes during specific spring break weeks. Easter travel periods see premium pricing.
June through August: Peak summer season brings the year’s highest prices as families vacation and pool season peaks. Expect $120-200+ for round-trip fares. This period should be avoided if budget is your primary concern.
September and October: Post-summer demand decreases while weather remains pleasant. Prices moderate to $89-130, making this an excellent window for budget travelers seeking good weather without peak season pricing.
November and December: Thanksgiving and Christmas weeks experience price spikes, but early November and mid-December offer opportunities. New Year’s Eve week commands premium prices, but December 26-30 often features discounted fares as travelers return home.
Alternative Airports and Routes
While Denver International Airport is the obvious departure point, exploring alternatives occasionally reveals savings. Denver’s secondary airport, Rocky Mountain Metropolitan Airport (BJC), handles limited commercial traffic but occasionally offers deals through regional carriers.
Las Vegas receives flights at Harry Reid International Airport (LAS), the primary airport, but some budget carriers experiment with alternative arrangements. Checking both airports ensures you capture all available options.
For Denver residents in southern Colorado, considering flights from Colorado Springs Airport (COS) sometimes yields savings, particularly on budget carriers. While driving to Colorado Springs adds time and fuel costs, significantly cheaper airfare occasionally justifies the effort.
Similarly, exploring flights from nearby airports like Pueblo Memorial Airport (PUB) for southern Colorado residents or considering Salt Lake City Airport (SLC) for northern Colorado travelers occasionally reveals cheaper options. The key is calculating total trip cost including ground transportation, not just airfare.
Loyalty Programs and Credit Card Rewards
Frequent flyer programs dramatically reduce effective airfare costs when strategically utilized. Southwest Rapid Rewards, United MileagePlus, and Delta SkyMiles all serve the Denver-Vegas route frequently, allowing point redemption for free or heavily discounted flights.
Co-branded airline credit cards offer sign-up bonuses typically worth $100-300 in travel value. If you meet minimum spending requirements through regular purchases, the bonus alone can cover multiple Denver-Vegas round-trips. Cards from Southwest, United, and Delta offer accelerated points on airline purchases, effectively discounting future flights.
For frequent Denver-Vegas travelers, elite status in loyalty programs provides additional benefits: priority boarding, free baggage, seat upgrades, and lounge access. These perks add value beyond discounted fares, particularly for business travelers or those making multiple trips annually.
Transfer partnerships with credit card companies occasionally provide better value than direct airline redemptions. Premium credit cards partnered with airlines sometimes allow point transfers at favorable rates, stretching your rewards further.
Hidden Fees and How to Avoid Them
Baggage fees, seat selection charges, and change fees can transform an apparently cheap flight into an expensive journey. Understanding each airline’s fee structure prevents unpleasant surprises at checkout.
Baggage Fees: Southwest includes two free checked bags, a significant advantage over competitors charging $30-40 per bag. For travelers with luggage, Southwest’s apparent higher base fare often results in lower total cost. Budget carriers like Frontier charge for carry-ons beyond a personal item, making their low fares deceptive for anyone with bags.
Seat Selection: Basic economy fares often exclude seat selection, with premium seating costing $10-25 extra. Choosing standard economy seats and accepting assigned seating saves money without sacrificing comfort on this short flight.
Change and Cancellation Policies: Budget carriers impose strict policies, charging $75-125 to change flights. Southwest’s free same-day changes and United’s more flexible basic economy policies provide valuable insurance against travel disruptions. For flexible travelers without firm plans, restrictive policies matter less.
Booking Directly vs. Third-Party Sites: While third-party booking sites sometimes show lower prices, booking directly with airlines ensures access to customer service and policy clarification. The small price difference rarely justifies the complications of third-party bookings.
Carefully review all fees during checkout before completing purchases. Many travelers inadvertently accept unnecessary charges by failing to uncheck optional services.

January and February typically offer the cheapest fares, with round-trip prices averaging $79-120. September and October provide excellent value combining lower prices with pleasant weather. Avoid June through August for budget-conscious travel, as peak summer pricing can reach $200+ for round-trips.
How far in advance should I book Denver to Las Vegas flights?
Booking 4-6 weeks in advance generally yields optimal prices. This window balances airline inventory release with avoiding last-minute surge pricing. For peak travel periods, booking 8 weeks ahead sometimes reveals better rates as airlines implement early booking incentives.
Which airline offers the best prices Denver to Vegas?
Frontier Airlines frequently offers the lowest base fares, but total costs including baggage fees may exceed Southwest’s transparent pricing. Southwest dominates the route with frequent flights and included baggage, often providing best overall value. Compare total costs including all fees rather than base fares alone.
Are Tuesday flights really cheaper than Friday flights?
Yes, Tuesday and Wednesday departures consistently cost 15-40% less than Friday and Sunday flights on the Denver-Vegas route. This reflects business travel patterns, with leisure travelers dominating weekends. If schedule flexibility exists, mid-week travel delivers significant savings.
Can I find flights under $100 round-trip Denver to Vegas?
Absolutely. Outside peak seasons, round-trip fares regularly fall below $100, particularly when booking 4-6 weeks in advance on Tuesday-Wednesday departures. Flash sales and error fares occasionally deliver even steeper discounts. Budget airlines like Frontier frequently advertise base fares starting at $39-49 one-way, though total costs with fees may exceed $100 round-trip.

This one-hour flight requires minimal packing. Bring a personal item with essentials: ID, boarding pass, medications, and valuables. Check baggage policies for your chosen airline—Southwest allows two free checked bags, while budget carriers charge $30-40 per bag.

Is it cheaper to drive from Denver to Las Vegas instead of flying?
Driving costs $80-120 in fuel plus wear-and-tear for the 750-mile journey, taking 11+ hours. Flying costs $80-200 round-trip and takes 4-5 hours total (including airport procedures). Flying is almost always faster and typically cheaper when comparing total trip time value. Driving only makes sense for road-trip enthusiasts or those combining multiple destinations.
How do I track price changes for Denver to Vegas flights?
Google Flights, Kayak, and Hopper offer price tracking and historical data. Set alerts on multiple platforms for your target dates, and check directly with airline websites weekly.

Should I book round-trip or one-way flights?
Round-trip bookings typically cost less than purchasing separate one-way tickets, even when returning on different dates. However, if your return date is uncertain, one-way flexibility might justify slightly higher costs. Calculate both options before deciding, as the Denver-Vegas route sometimes features pricing anomalies favoring one approach over the other.
