Atlanta to Colorado Springs

What the Data Says About ATL to COS

The Atlanta to Colorado Springs corridor (ATL → COS) covers roughly 1,184 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,128 flights in the dataset, this route posts a 76.5% on-time rate with an average delay of 65.6 minutes when flights run late. Over the most recent 24 months of BTS data, 1,005 flights were recorded on this pairing — 10 cancelled (1.0%) and 2 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,128 total flights analyzed, the 76.5% on-time figure is statistically meaningful rather than a small-sample fluke. The 65.6-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Oct 2025 posted the best performance on this corridor at 83% on-time, while Jul 2024 came in at 56% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the ATL to COS route, the combination of a 76.5% on-time rate, 65.6-minute average delay, 1.0% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
