About this list
Colorado's airport list is built by taking every US airport in the source dataset, computing the great-circle distance from each airport to all 52 state centroids, and grouping the airport under the closest one. Every state ends up with a populated page that way, including the small states that share their nearest international gateway with a neighbour. The flip side is that a handful of airports very close to a state border get filed under the neighbouring side.
The departures column reflects the number of distinct scheduled routes recorded against each airport in the OpenFlights routes table. A high count usually indicates a hub or focus city for one or more carriers; a low count typically points to seasonal or single-carrier service. For an authoritative real-time view, always confirm schedules with the operating airline.
Connecting onward
Most travelers in Colorado reach long-haul destinations by connecting through a larger national or international hub. On any airport page below, the destinations table links straight through to the destination airport, where you can repeat the drill-down to see how onward connections fan out from there. Browsing this way gives you a feel for how a state plugs into the wider US and global network. Even small airports usually sit one or two hops away from any major world city.
