You can fly into the Colorado Springs or the Denver Airport.

Flying into Colorado Springs:

The Colorado Springs airport is convenient if you do not plan to rent a car. I do recommend that you rent a car if you want to go sight seeing. If you plan to stay downtown the wedding venue and a variety of restaurants are all in walking distance of the recommended hotels. Flying into Colorado Springs can be a bit pricey compared to Denver, but nice if you are staying local.

Flying into Denver:

Denver's airport is a bit outside of Denver and about 1.5-2 hours away from the wedding venue/hotel recommendations in Colorado Springs. It is a great option if you plan to rent a car and explore Denver, Colorado Springs, and other Colorado locations before or after the wedding. Denver usually has cheaper flight options than Colorado Springs offers.
