Pay a little more and go with American or United. Also, fly earlier in the day. It seems that night flights have the crankiest crews on Southwest.

Alaska Air is very efficient & on-time so allow enough time to get luggage, go thru Customs & Immigration, & long security lines. Terminals in SEA are readily accessible by trains but more signage is needed. Fortunately, Information booths are everywhere & are manned by very helpful staff.

FAQs - booking Colorado flights

  • Where is the closest airport if I want to quickly start exploring Colorado’s mountains?

    Colorado is home to many mountains and ski resorts. Booking a flight to Durango via Durango–La Plata County Airport will put you close to the Purgatory Resort. However, it will still be a 44 mi rental car ride to the mountains. A flight to Aspen–Pitkin County Airport will put you near Crested Butte Mountain Resort, and driving to this magnificent resort will take 3h 5m.

  • What is the closest airport to the Rio Grande National Forest?

    Consider booking a flight to Colorado Springs, then renting a car and driving to the Rio Grande National Forest (4h 20m). You can also book a flight to the smaller airport located in the town of Durango (Durango–La Plata County Airport). It’s about a 2h 52m drive from Durango to the national forest. However, flights to Colorado Springs are less expensive and more frequent.

  • Where can I book a flight to Colorado?

    The state has several airports you can arrive in and depart from. The main four hubs are Aspen–Pitkin County Airport, located in the middle of the state; the City of Colorado Springs Municipal Airport in the southern part of the state; Denver International Airport, the most popular and busiest airport in the state; and Durango–La Plata County Airport, which is the best for anyone wanting to travel to the Southwest.

  • What is the best airport to get to Durango, Colorado?

    Durango is on the outskirts of basically everything. You can reach it directly by flying to Durango–La Plata County Airport, but while flights here may be more frequent, they are also more expensive. Consider flying to Albuquerque, NM, via Albuquerque International Sunport (ABQ), and then booking a rental car and driving the 217 mi to Durango. It’s closer and cheaper than flying to either Denver or Pueblo.

  • How does KAYAK find such low prices on flights from the United States to Colorado?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from the United States to Colorado.

  • What is the Hacker Fare option on flights from the United States to Colorado?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional round-trip ticket. You could then fly from the United States to Colorado with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from the United States to Colorado?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from the United States to Colorado up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

  • To reach the capital city of Denver, Colorado, consider booking a flight to the Denver International Airport (DEN). The airport is not located in the city (26 mi), so be prepared for about an hour-long rental car drive.
  • To reach the Rocky Mountain State Park, consider booking a flight to the Denver airport. It is the northern-most major hub for the park and offers the best choice for anyone wanting to see the northern region of Colorado.
  • The Denver International Airport is a good place to fly for anyone wanting to visit nearby cities. It is located near a few of Colorado’s most popular towns, like Boulder (42m) and Aurora (20m). You can then book nonstop flights from Denver to other parts of the state for cheaper.
  • For fliers coming in from the West Coast, like Los Angeles International Airport (LAX), flights will be significantly cheaper. Flights from East Coast cities, such as Alabama’s Birmingham-Shuttlesworth International Airport (BHM), are going to be more expensive but more frequent.
  • If you want to get to the middle of Colorado, consider booking a flight to Aspen. While flights may be more expensive here, the only other way to reach the city is a lengthy car ride from Denver or Durango.
