Across 1,117 flights in the dataset, this route posts a 87.7% on-time rate with an average delay of 79.5 minutes when flights run late.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 1,117 total flights analyzed, the 87.7% on-time figure is statistically meaningful rather than a small-sample fluke. The 79.5-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, Sep 2024 posted the best performance on this corridor at 96% on-time, while Mar 2025 came in at 73% on-time — a 23-point gap between best and worst recent month. For travelers evaluating the PHX to PSC route, the combination of a 87.7% on-time rate, 79.5-minute average delay, 0.0% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
