Madison to Phoenix

What the Data Says About MSN to PHX

The Madison to Phoenix corridor (MSN → PHX) covers roughly 1,396 miles and is served by 10 carriers, based on Bureau of Transportation Statistics reporting. Across 2,225 flights in the dataset, this route posts a 83% on-time rate with an average delay of 121.5 minutes when flights run late. Over the most recent 24 months of BTS data, 908 flights were recorded on this pairing — 4 cancelled (0.4%) and 2 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 10 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,225 total flights analyzed, the 83% on-time figure is statistically meaningful rather than a small-sample fluke. The 121.5-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 2025 posted the best performance on this corridor at 84% on-time, while Apr 2025 came in at 77% on-time — a 7-point gap between best and worst recent month. For travelers evaluating the MSN to PHX route, the combination of a 83% on-time rate, 121.5-minute average delay, 0.4% recent cancellation rate, and 10 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
