Frequently Asked Questions About the Cheapest Colorado Airports to Fly Into

Before we wrap up, let’s tackle some frequently asked questions about the cheapest airports to fly into Colorado to help you plan your trip even better. Here’s everything you need to know about flights to Colorado:

Which airport in Colorado is cheapest to fly into?

The cost of flying into Colorado can vary widely depending on several factors, such as your departure city, the time of year, and how far in advance you book. However, Denver International Airport (DEN) often emerges as the cheapest airport to fly into Colorado. This is primarily because Denver serves as a major hub for several airlines, including United and Southwest.

The high volume of flights going in and out of DEN creates a competitive environment, which often leads to lower fares. Additionally, Denver frequently offers special promotions and discounts, especially during off-peak seasons, making it a budget-friendly option for many travelers.

Is it better to fly into Vail or Denver?

Whether it’s better to fly into Vail or Denver depends on your priorities, budget, and travel plans. Here are some considerations to help you decide:

Flying into Vail (Eagle County Regional Airport – EGE):

1. Convenience: If Vail or nearby ski resorts are your primary destination, flying directly into Eagle County Regional Airport can save you the drive from Denver, which can be especially beneficial during winter months when mountain passes can be treacherous.
2. Smaller Airport: EGE is a smaller airport, which often means quicker check-ins and less hassle compared to larger airports.
3. Scenic: The flight into Vail offers breathtaking mountain views.
4. Cost: Flights directly into Vail can be more expensive than flights into Denver, especially if coming from farther away.
5. Limited Flight Options: There are fewer flights and routes available to EGE compared to Denver, which might limit flexibility.

Flying into Denver (Denver International Airport – DIA):

1. More Flight Options: DIA is a major international airport with numerous daily flights from a wide range of domestic and international locations. This can offer more flexibility in terms of flight times and often more competitive prices.
2. Cost: Generally, flights into Denver can be cheaper than flights into Vail, especially if you’re booking well in advance or catching a deal.
3. Drive: The drive from Denver to Vail is about 2 hours without traffic, but this can vary greatly depending on weather conditions, especially in winter. The drive, though, is scenic and takes you through the Rocky Mountains.
4. Versatility: If you’re planning to visit other parts of Colorado in addition to Vail, flying into Denver might offer more flexibility.

What’s the cheapest time to fly to Colorado?

The most budget-friendly times to fly to Colorado are generally the shoulder seasons of late spring and early fall. During these months, the state sees fewer tourists. This often leads airlines to offer special promotions and discounts to fill seats. If you’re flexible with your travel dates, you can take advantage of these lower prices by booking a few months in advance. It’s also worth noting that prices can spike during major events or festivals, so it’s wise to check the local calendar before booking your trip.

What time of day are flights cheapest?

Flights are generally most affordable during off-peak hours. This usually means flying mid-week or during inconvenient times like late at night or very early in the morning. These less popular times are less likely to fill up, prompting airlines to lower prices to attract passengers. However, this isn’t a hard and fast rule and can vary depending on the airline and the specific route. Therefore, it’s always a good idea to compare prices for different times and days when planning your trip.

How far in advance should I book my flight to Colorado?

For the best fares, aim to book your flight to one of the cheapest airports to fly into Colorado around 50 to 100 days before your planned departure. Airlines often release their most competitive fares during this window. However, this can vary depending on the time of year and the popularity of the route. If you’re planning to travel during peak seasons like winter for skiing or summer for hiking, you may need to book even further in advance to secure the best rates.

Are smaller airports cheaper than larger ones?

Smaller airports like Colorado Springs Airport (COS) or Pueblo Memorial Airport (PUB) can offer competitive prices. It is mainly due to their lower operational costs and fewer amenities. However, these airports may have fewer flight options, which could limit your flexibility. It’s essential to weigh the cost savings against the convenience and availability of flights when choosing an airport.

Where is the best place to fly into Colorado?

The best place to fly into Colorado largely depends on your intended destinations and activities within the state. Here are the major airports in Colorado and their advantages:

1. Denver International Airport (DIA):
   • Advantages: It’s the largest airport in Colorado and one of the busiest in the U.S. This means it offers the most flight options, often at competitive prices. It’s a hub for many major airlines. From DIA, you have easy access to Denver, Boulder, and it’s a gateway to the Rocky Mountains and ski resorts like Breckenridge, Vail, and Aspen (though these are still a drive away).
2. Colorado Springs Airport (COS):
   • Advantages: Located in the southern part of the state, it’s a smaller and less hectic alternative to DIA. It’s ideal if your primary destinations are Colorado Springs, Pikes Peak, Garden of the Gods, or other southern Colorado attractions.
3. Aspen/Pitkin County Airport (ASE):
   • Advantages: If you’re heading straight to Aspen for skiing or festivals, flying directly into this airport can save you a long drive from Denver. However, flights might be pricier and more limited.
4. Eagle County Regional Airport (EGE):
   • Advantages: Located closer to ski resorts like Vail and Beaver Creek, it’s a convenient option during the ski season. Like Aspen, flights might be more limited and potentially more expensive.
5. Grand Junction Regional Airport (GJT):
   • Advantages: If you’re exploring the western part of Colorado, like the Colorado National Monument or the wine country around Palisade, this airport is a good choice.

Is it cheaper to fly into Colorado and then drive to my final destination?

Sometimes flying into a major airport like Denver International Airport (DEN) and then driving to your final destination can be more cost-effective, especially if you’re heading to a less accessible area of the state. However, this approach adds the extra time and potential cost of car rental or other forms of transportation. Therefore, it’s crucial to consider these additional factors and calculate the total cost to see if this option makes sense for your trip.

Do airlines offer package deals for Colorado destinations?

Yes, airlines frequently offer package deals, particularly for high-traffic tourist destinations like the ski resorts in Vail or Aspen. These packages often include not just flights but also accommodations and sometimes even ski passes or other activity tickets. By bundling these elements, you can often save a significant amount compared to booking each component separately.

How can I find the best flight deals to Colorado?

To secure the best flight deals, it’s advisable to use a combination of search engines and fare alert services. This approach allows you to compare prices from multiple sources and be notified when fares drop. Additionally, consider flying mid-week or being flexible with your travel dates, as these factors can significantly impact the cost of flights. Lastly, don’t forget to check the airlines’ own websites, as some carriers reserve their best fares for customers who book directly, and you may also avoid additional booking fees.

Final Thoughts on Colorado’s Cheapest Airports

Choosing the right airport can make all the difference when planning your Colorado adventure, both in terms of cost and convenience. From bustling hubs like Denver International Airport (DEN) to smaller, more specialized airports like Alamosa San Luis Valley Regional Airport (ALS), Colorado offers a range of options to fit every traveler’s needs and budget.

The key to finding the best deals is flexibility. Being open to flying at different times of the day, or even into different airports, can yield significant savings. And remember, the cheapest airports to fly into Colorado aren’t always the most obvious ones. Smaller airports often offer competitive prices and can be closer to your final destination, saving you both time and money.

Timing is also crucial. The cheapest fares are often found during Colorado’s shoulder seasons in late spring and early fall. However, if winter sports are your thing, keep an eye out for package deals that can make even the more expensive airports more affordable.
