9 Things Colorado Travelers Know About Booking Flights That Most Don't

Colorado travelers don’t just book flights – they outsmart the weather, the airlines, and even the mountains. Flying in and out of Denver International Airport comes with unique challenges that locals have learned to navigate like pros. From unpredictable weather patterns to understanding which airlines offer the best deals, frequent flyers from the Centennial State have developed strategies that save them time, money, and stress. Here are 9 insider tips that frequent flyers from the Centennial State swear by.

United and Southwest dominate Denver’s airspace, controlling nearly 80 percent of all flights through DIA. This isn’t just a fun fact – it’s critical information for booking smart. United operates a major hub at Denver, offering extensive domestic and international connections. Southwest brings its no-frills, two-free-bags approach that appeals to budget-conscious travelers.

Competition between these giants occasionally sparks fare wars that locals monitor like hawks. When one airline drops prices on a popular route, the other often matches within days. Savvy Colorado travelers compare both carriers religiously, knowing that loyalty to just one means potentially missing out on hundreds of dollars in savings.

Each airline has distinct advantages. United offers more destinations and premium cabin options, while Southwest provides flexibility with no change fees and generous baggage policies. Understanding these differences helps you choose the right carrier for your specific trip needs.

2. Fly Early – The Mountains Don’t Wait

Morning flights out of Denver International Airport aren’t just convenient – they’re strategic. Locals know that departures between 6 and 9 a.m. offer the smoothest rides because mountain wave winds haven’t built up yet. These powerful air currents form when westerly winds slam into the Rockies, creating turbulence that can rattle even experienced travelers.

By choosing an early departure, you’re essentially beating Mother Nature to the punch. The atmosphere is calmer, delays are less common, and your chances of a bumpy ride drop significantly. Plus, morning flights mean you arrive at your destination with a full day ahead of you.

Frequent Colorado flyers swear by this trick, especially during winter months when weather can turn quickly. Setting that early alarm might be tough, but the payoff is a reliable, comfortable flight that gets you where you need to go without drama.

3. Expect Four Seasons – in One Day

Colorado’s weather reputation isn’t exaggerated – it really can snow in September and hit 70 degrees by afternoon. This unpredictability directly impacts flight schedules at DIA. Snow can appear from September through May, strong winds blow year-round, and summer thunderstorms roll in with little warning.

Smart travelers build flexibility into their itineraries. Avoid booking tight connections during peak storm seasons, especially November through March. That thirty-minute layover might seem efficient, but one snow squall can turn it into a missed connection and a nightmare rebooking situation.

Experienced Colorado flyers check weather forecasts obsessively before travel days. They pack layers regardless of the season and always have a backup plan. Airlines often waive change fees during severe weather, so knowing your rights can save you money. When flying through Colorado, expect the unexpected and plan accordingly – that’s the local way.

4. Master the Goldilocks Window

Timing really is everything when booking Colorado flights. Book too early and you’ll pay premium prices set by algorithms predicting high demand. Wait too long and you’re competing with desperate travelers willing to pay anything for remaining seats. Locals have figured out the sweet spot – the Goldilocks window where prices are just right.

For domestic flights, aim for one to three months in advance. Peak seasons like ski season and holidays require more planning, so book three to five months ahead for those trips. This timing consistently yields the best balance between availability and affordability.

Airlines use sophisticated pricing systems that constantly adjust fares based on demand patterns. Experienced Colorado travelers understand these rhythms and plan accordingly. They mark their calendars, set reminders, and book when the window opens. Missing this optimal period often means paying fifty to two hundred dollars more for the exact same seat.

5. Look Beyond Denver

Denver International Airport handles most Colorado air traffic, but it’s not your only option. Colorado Springs Airport sits just ninety minutes south and often offers cheaper fares with dramatically shorter security lines. While flight options are more limited, the convenience and savings can make it worthwhile for flexible travelers.



Locals living along the Front Range routinely compare both airports before booking. A fifty-dollar fare difference plus an hour saved in security lines adds up quickly. Colorado Springs works especially well for direct flights to major hubs like Dallas, Phoenix, or Los Angeles.



The trade-off is fewer daily departures and limited destinations compared to Denver’s massive network. But if your schedule aligns with available flights, you’ll enjoy a more relaxed airport experience. Parking is cheaper, terminals are easier to navigate, and the overall stress level drops considerably. Sometimes the best deal isn’t at the biggest airport.

6. Understand the Altitude Factor

Denver International Airport sits at 5,430 feet above sea level, making it one of the highest major airports in North America. This elevation isn’t just trivia – it affects how planes perform, especially on scorching summer days. Thin air at high altitude provides less lift, forcing planes to use longer runways and sometimes restrict passenger or cargo weight.

On particularly hot days, airlines may bump passengers or luggage to keep planes within safe operating limits. Savvy travelers know that morning flights avoid these heat-related issues because cooler temperatures mean denser air and better aircraft performance.

This altitude factor also explains why takeoffs from Denver feel longer than at sea-level airports. Pilots need more runway to achieve necessary speed for liftoff in thin mountain air. Understanding these physics helps manage expectations and explains occasional weight restrictions that might seem arbitrary. Colorado flyers take altitude seriously because it directly impacts their travel plans.

7. Automate Your Search

Constantly checking flight prices manually is exhausting and ineffective. Colorado’s experienced travelers automate the process using tools like Google Flights, Hopper, and Skyscanner. These platforms monitor fares continuously and send alerts when prices drop, eliminating guesswork and saving countless hours of manual searching.



Setting up price alerts takes five minutes but pays dividends throughout the year. Simply enter your desired route and travel dates, and the apps track pricing trends while you focus on other things. When fares drop to favorable levels, you receive instant notifications with booking links ready to go.



This strategy proves especially valuable during high-demand seasons like ski trips or fall foliage getaways when prices fluctuate wildly. Instead of gambling on the right booking moment, you let technology do the heavy lifting. Locals who fly regularly swear by automation, claiming it saves them hundreds of dollars annually while reducing booking stress to nearly zero.

8. Watch the 24-Hour Rule

Did you know most U.S. airlines let you cancel bookings within twenty-four hours without penalties? This federal regulation creates a risk-free window that smart travelers exploit ruthlessly. After booking, experienced Colorado flyers continue monitoring prices for that full day, ready to cancel and rebook if fares drop.

This isn’t being sneaky – it’s using consumer protections to your advantage. Airlines change prices constantly based on demand algorithms, and fares can drop significantly even hours after you book. Checking again before the twenty-four-hour window closes costs nothing but potentially saves substantial money.

The process is straightforward: book your flight, set a reminder for twenty-three hours later, then search again for the same route. If you find a better price, cancel your original booking and purchase the cheaper ticket. Some travelers save fifty to three hundred dollars using this simple strategy. It requires a bit of diligence, but the potential savings make it worthwhile for budget-conscious flyers.

9. The Hidden City Hack – At Your Own Risk

This controversial strategy involves booking a flight with a layover at your actual destination, then skipping the final leg. For example, a Denver-to-Chicago ticket might cost three hundred dollars, but Denver-to-New York with a Chicago layover might cost just two hundred. Some travelers book the cheaper option and simply leave the airport in Chicago.



Airlines absolutely hate this practice and consider it a violation of their contracts of carriage. Getting caught could result in ticket cancellation, frequent flyer account termination, or being billed the fare difference. It only works with carry-on luggage since checked bags continue to the final destination.



Colorado locals whisper about this hack but acknowledge the risks. It’s occasionally used for expensive one-way fares where price differences are extreme. However, most experienced travelers reserve it as a last resort, understanding that airlines are cracking down harder. Use extreme caution and understand you’re technically violating airline policies if you choose this route.
