Small airport, but efficient. Very passenger friendly. No big lines. Limited food and souvenir options, but still very smooth and quiet. They play nice and cool music in the background.
Though the Muzak may drive you to distraction, COS offers free wifi, in-seat power outlets in many of their seats, and an amazing view of the Springs' signature landmark: Pike's Peak.
Nice airport! Would pick this over DEN if fares are close. Limited food past checkpoints, so if time allows eat before you get groped by the screeners.
Lately the United counter has been severely understaffed. Expect over an hour from the time you arrive until hitting your gate if your flight is early in the AM, not fun
