Montrose/Delta to Chicago

What the Data Says About MTJ to ORD

The Montrose/Delta to Chicago corridor (MTJ → ORD) covers roughly 1,081 miles and is served by 12 carriers, based on Bureau of Transportation Statistics reporting. Across 813 flights in the dataset, this route posts a 84.4% on-time rate with an average delay of 105.5 minutes when flights run late. Over the most recent 24 months of BTS data, 813 flights were recorded on this pairing — 27 cancelled (3.3%) and 8 diverted (1.0%). 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 813 total flights analyzed, the 84.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 105.5-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 95% on-time, while Mar 2022 came in at 88% on-time — a 7-point gap between best and worst recent month. For travelers evaluating the MTJ to ORD route, the combination of a 84.4% on-time rate, 105.5-minute average delay, 3.3% recent cancellation rate, and 12 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
