Colorado Springs to Atlanta

What the Data Says About COS to ATL

The Colorado Springs to Atlanta corridor (COS → ATL) covers roughly 1,184 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 1,129 flights in the dataset, this route posts a 86.6% on-time rate with an average delay of 95.3 minutes when flights run late. Over the most recent 24 months of BTS data, 1,006 flights were recorded on this pairing — 11 cancelled (1.1%) and 6 diverted (0.6%). 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 1,129 total flights analyzed, the 86.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 95.3-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 98% on-time, while Nov 2024 came in at 71% on-time — a 27-point gap between best and worst recent month. For travelers evaluating the COS to ATL route, the combination of a 86.6% on-time rate, 95.3-minute average delay, 1.1% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
