Flying from Los Angeles to Denver is one of the most frequently traveled routes in the western United States, connecting two vibrant cities just 1,000 miles apart. Whether you’re heading to Colorado’s Mile High City for business, outdoor adventures, or a quick mountain getaway, finding affordable airfare can significantly stretch your travel budget. This comprehensive guide reveals insider strategies, timing secrets, and booking hacks that savvy travelers use to score the cheapest Denver flights from LAX.
The LAX-to-Denver corridor offers competitive pricing due to multiple airlines operating the route and consistent demand throughout the year. However, prices fluctuate dramatically based on booking timing, seasonal factors, and day-of-week variations. Understanding these patterns gives you a substantial advantage when hunting for deals on this popular domestic route.
Best Time to Book Denver Flights from LAX
Timing your booking is absolutely critical when searching for cheap Denver flights from LAX. Industry data consistently shows that booking 1-3 months in advance offers the sweet spot for domestic flights, with prices typically 20-30% lower than last-minute bookings. For the LAX-Denver route specifically, booking 45-60 days ahead frequently yields the lowest fares.
The “Tuesday-Wednesday effect” remains remarkably reliable for this route. Airlines traditionally release their lowest fares on Tuesday afternoons, and competitors match these prices by Wednesday morning. Setting up price alerts on Tuesday evening and checking Wednesday morning gives you first access to these deals. Avoid booking on Friday, Saturday, or Sunday when airlines know leisure travelers are planning weekend trips and price accordingly.
Mid-week departures (Tuesday through Thursday) consistently offer 15-25% savings compared to weekend flights. A Tuesday morning departure from LAX to Denver might cost $120-150, while the same flight on Friday could easily run $200-250. If your schedule permits flexibility, shifting your travel dates by just one or two days can yield substantial savings.
Booking during off-peak hours matters too. Early morning searches (6-8 AM) and late evening searches (after 10 PM) sometimes reveal better prices than midday bookings. This timing variation relates to airline pricing algorithms and real-time inventory management. Some travelers swear by clearing their browser cookies before searching, though best airlines for long flights analysis suggests this has minimal impact on domestic routes.
Airlines Operating LAX to Denver
Four major carriers dominate the LAX-Denver market: Southwest Airlines, United Airlines, Frontier Airlines, and Delta Air Lines. Each offers distinct pricing strategies and amenities worth comparing.
Southwest Airlines typically offers competitive base fares, though their bags-fly-free policy adds value. They operate multiple daily flights on this route with flexible change policies that justify slightly higher ticket prices. Southwest’s lack of seat selection and boarding process differences mean you’ll want to factor in early-bird check-in costs if seat selection matters to you.
Frontier Airlines frequently advertises the absolute lowest base fares, often undercutting competitors by $20-40 per ticket. However, their ultra-low-cost model charges separately for carry-ons, seat selection, and checked baggage. A “cheap” Frontier fare of $89 might actually cost $150+ once you add necessary fees. Calculate total costs before assuming Frontier is the best deal.
United Airlines offers several daily flights with reasonable pricing and better frequent flyer integration if you’re a member. Their hub presence in Denver means they’re motivated to fill flights, sometimes resulting in competitive fares. United’s checked baggage fees and seat selection charges apply unless you have premium status.
Delta Air Lines typically prices slightly higher than competitors but offers consistent service and reliability. Their SkyMiles program provides decent value for frequent travelers on this route. Delta’s partnership with international carriers might offer advantages if you’re connecting internationally from Denver.
Cheapest Days and Times to Fly
Historical data for LAX-Denver flights shows consistent pricing patterns throughout the week. Tuesday and Wednesday departures average 18-22% cheaper than Friday-Sunday flights. Early morning departures (5-8 AM) often cost less than afternoon (12-4 PM) or evening (5-10 PM) flights, partly because business travelers avoid early morning slots and leisure travelers prefer convenient times.
Red-eye flights (departing 10 PM or later, arriving after midnight) occasionally offer 15-20% discounts, though the travel experience trade-off rarely justifies the savings unless you’re extremely price-sensitive. Flights departing LAX around 6-7 AM and arriving in Denver by 8-9 AM typically represent the best balance of low fares and reasonable timing.
Monthly patterns show that flying mid-month (the 10th-20th) generally costs less than flying at month-start or month-end when business travelers book. Avoid traveling during school holidays, major holidays (Thanksgiving, Christmas, Spring Break), and peak ski season (December-March weekends) when Denver flights surge 40-60% in price.
The absolute cheapest flights typically occur in late August-early September, late April-early May, and mid-September through early November. These shoulder seasons offer pleasant Denver weather without peak demand pricing. Summer (June-August) brings consistent moderate pricing, while winter weekend flights command premium prices due to ski resort proximity.
Money-Saving Strategies and Hacks
Beyond basic timing strategies, several advanced techniques consistently yield cheaper Denver flights from LAX.
Price Monitoring Tools should be your first step. Google Flights, Kayak, and Hopper allow you to set price alerts for specific dates or flexible date ranges. These tools notify you when fares drop, helping you capitalize on flash sales. Hopper’s predictive pricing algorithm sometimes suggests the optimal booking window for your specific travel dates.
Incognito Mode Browsing prevents airlines from tracking your search history and raising prices based on repeated searches. While this is somewhat debated, using incognito/private browsing costs nothing and might provide marginal savings. Clear your cookies between searches across different booking sites.
Flexible Date Searching reveals how fares vary across a week. Most booking sites show calendar views displaying prices for each date. Shifting your departure by 1-2 days might reveal $50-100+ savings. If you have even basic schedule flexibility, always check multiple date combinations before booking.
Mistake Fares and Flash Sales occasionally appear when airlines misprice routes or run limited-time promotions. Following travel deal websites like The Points Guy and Scott’s Cheap Flights alerts you to these opportunities. Setting up notifications for LAX-Denver specifically helps you catch deals within minutes of posting.
Connecting Flight Strategies sometimes beat direct flights. Flights from LAX to Denver with a stop in Las Vegas, Phoenix, or Salt Lake City occasionally cost $30-80 less than direct flights, though the time trade-off rarely justifies this for a 1,000-mile route. Only consider connections if you have significant schedule flexibility.
Booking one-way flights separately rather than round-trips occasionally yields savings, particularly if your outbound and return flights have different pricing dynamics. Compare round-trip pricing against two separate one-way bookings before finalizing your purchase.
Alternative Airports and Routes
While Denver International Airport (DEN) is the primary destination, considering alternative airports can reveal cheaper options. Long Beach Airport (LGB), located just 30 miles south of LAX, sometimes offers cheaper flights than LAX itself. Burbank Airport (BUR) and Ontario International Airport (ONT) occasionally feature competitive fares for Denver routes.
Flying into Denver and considering alternative Colorado airports rarely makes sense given Denver’s central location, but if you’re planning a road trip, Colorado Springs Airport (COS) is worth comparing. Occasionally, flights to COS are cheaper, and the 90-minute drive to Denver might be worthwhile for significant savings.
The reverse route comparison—searching Denver to LAX instead of LAX to Denver—sometimes reveals pricing asymmetries. Airlines occasionally price directional routes differently based on demand patterns. Checking both directions takes two minutes and might save $20-40.
Seasonal Pricing Patterns
Denver’s unique position as a gateway to world-class skiing and outdoor recreation creates pronounced seasonal pricing variations. Winter (December-February) brings peak prices, particularly weekends, when ski enthusiasts flood Denver. Expect $250-350+ for weekend flights during ski season.
Spring (March-May) offers moderate pricing with improving weather. April and early May provide excellent value, with fares typically $120-180 for off-peak dates. This shoulder season combines reasonable prices with pleasant Denver weather perfect for outdoor activities.
Summer (June-August) brings consistent moderate pricing around $140-200 for mid-week flights. While school vacations create some price spikes, summer generally offers better deals than winter. Late August transitions toward fall pricing as families return to school routines.
Fall (September-November) provides the year’s best value. September and October offer $100-150 fares with perfect hiking weather and fewer crowds. Early November maintains low prices before Thanksgiving travel surge. Late November through Thanksgiving sees significant price increases.
Loyalty Programs and Credit Cards
Frequent flyer programs amplify savings on Denver flights from LAX. Southwest’s Rapid Rewards, United’s MileagePlus, and Delta’s SkyMiles all offer redemption opportunities on this popular route. Earning miles through credit card sign-up bonuses often provides better value than purchasing miles directly.
Travel credit cards offering airline-specific bonuses make sense if you fly this route regularly. A card providing 50,000 Southwest miles after meeting spending requirements effectively covers 8-10 round-trip flights to Denver. Annual benefits and lounge access add further value for frequent travelers.
Combining flight booking strategies with credit card rewards can yield free flights faster than expected. Some travelers strategically book paid flights during high-bonus earning periods, accumulating miles quickly for future travel.
If you’re not a frequent flyer, comparison shopping between booking paid flights and using accumulated miles depends on your specific program balances and redemption rates. Generally, domestic redemptions at 1-1.5 cents per mile value make sense for flights costing $150+.
Exploring various flight routes and booking options across different programs helps identify which loyalty program offers best value for your travel patterns. Some travelers maintain accounts with multiple programs to maximize flexibility and options.
Now that you understand the intricacies of Denver flight pricing from LAX, let’s explore how these strategies compare to flights from Atlanta to Miami and other competitive domestic routes. The principles remain consistent—timing, flexibility, and strategic booking yield the best results regardless of route.
FAQ
What’s the average price for LAX to Denver flights?
Typical fares range $100-200 for off-peak mid-week flights, with weekend and peak season flights often $200-350+. Exact pricing depends heavily on booking timing, season, and how far in advance you book.
How far in advance should I book Denver flights from LAX?
The optimal booking window is 45-60 days before departure. Booking less than two weeks ahead typically results in 30-50% price premiums. Booking more than three months ahead occasionally reveals better deals but limits flexibility.
Which airline offers the cheapest fares?
Frontier usually advertises the lowest base fares, but total costs including baggage fees often exceed Southwest or United. Compare all-in pricing rather than base fares alone. United and Southwest frequently offer better value when factoring in included amenities.
Are Tuesday flights really cheaper?
Yes, Tuesday departures and bookings consistently show 15-25% savings compared to weekend flights. Wednesday departures also offer excellent pricing. This pattern holds reliably across the LAX-Denver route.
Should I book a round-trip or two separate one-way flights?
Round-trip bookings usually offer better value, but occasionally splitting into two one-way bookings saves money. Always compare both options before booking. Price differences are typically small (under $20) unless major pricing asymmetries exist.
What about red-eye flights to Denver?
Red-eyes occasionally offer 15-20% discounts, but the trade-off of arriving after midnight rarely justifies the savings unless you’re extremely price-sensitive. Early morning flights often provide better balance between price and convenience.
Can I find cheaper flights by flying into alternative Colorado airports?
Colorado Springs (COS) occasionally shows lower fares, but the 90-minute drive to Denver usually doesn’t justify the savings. Long Beach or Ontario airports near LAX sometimes beat LAX pricing by $10-20, worth checking if you’re driving from those areas anyway.
How do I use price alerts effectively?
Set alerts on Google Flights or Hopper for your specific travel dates and flexible date ranges. Check alerts Tuesday evenings when new fares release. Act quickly on significant price drops, as deals often fill within hours.
Is travel insurance worth it for Denver flights?
For short domestic flights, travel insurance rarely provides value unless you’re booking non-refundable deep-discount fares and have significant flexibility needs. Premium credit cards often include trip cancellation coverage, eliminating the need for separate insurance.
What’s the best way to find mistake fares for this route?
Follow Scott’s Cheap Flights and Airfare Watchdog for deal alerts. Set up specific notifications for LAX-Denver routes. Act immediately when deals post, as availability disappears quickly.
