Grand Junction to Phoenix

What the Data Says About GJT to PHX

The Grand Junction to Phoenix corridor (GJT → PHX) covers roughly 438 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 5,435 flights in the dataset, this route posts a 86.8% on-time rate with an average delay of 98.6 minutes when flights run late. Over the most recent 24 months of BTS data, 2,052 flights were recorded on this pairing — 9 cancelled (0.4%) and 4 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 9 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,435 total flights analyzed, the 86.8% on-time figure is statistically meaningful rather than a small-sample fluke. The 98.6-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, Jan 2025 posted the best performance on this corridor at 97% on-time, while Feb 2024 came in at 75% on-time — a 22-point gap between best and worst recent month. For travelers evaluating the GJT to PHX route, the combination of a 86.8% on-time rate, 98.6-minute average delay, 0.4% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
