Chicago to Montrose/Delta

What the Data Says About ORD to MTJ

The Chicago to Montrose/Delta corridor (ORD → MTJ) covers roughly 1,081 miles and is served by 12 carriers, based on Bureau of Transportation Statistics reporting. Across 814 flights in the dataset, this route posts a 79.9% on-time rate with an average delay of 58.6 minutes when flights run late. Over the most recent 24 months of BTS data, 814 flights were recorded on this pairing — 18 cancelled (2.2%) and 4 diverted (0.5%). Those baseline metrics tell you what to expect before you book.

Having 12 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 814 total flights analyzed, the 79.9% on-time figure is statistically meaningful rather than a small-sample fluke. The 58.6-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, Mar 2021 posted the best performance on this corridor at 93% on-time, while Mar 2022 came in at 86% on-time — a 8-point gap between best and worst recent month. For travelers evaluating the ORD to MTJ route, the combination of a 79.9% on-time rate, 58.6-minute average delay, 2.2% recent cancellation rate, and 12 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
