What the Data Says About IDA to DFW

The Idaho Falls to Dallas/Fort Worth corridor (IDA → DFW) covers roughly 1,095 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 2,581 flights in the dataset, this route posts a 79.3% on-time rate with an average delay of 120.9 minutes when flights run late. Over the most recent 24 months of BTS data, 1,098 flights were recorded on this pairing — 14 cancelled (1.3%) and 11 diverted (1.0%). 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 2,581 total flights analyzed, the 79.3% on-time figure is statistically meaningful rather than a small-sample fluke. The 120.9-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, Aug 2024 posted the best performance on this corridor at 87% on-time, while Oct 2025 came in at 61% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the IDA to DFW route, the combination of a 79.3% on-time rate, 120.9-minute average delay, 1.3% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
