Chicago to Palm Springs

What the Data Says About ORD to PSP

The Chicago to Palm Springs corridor (ORD → PSP) covers roughly 1,651 miles and is served by 8 carriers, based on Bureau of Transportation Statistics reporting. Across 2,939 flights in the dataset, this route posts a 81% on-time rate with an average delay of 63.1 minutes when flights run late. Over the most recent 24 months of BTS data, 1,820 flights were recorded on this pairing — 9 cancelled (0.5%) and 4 diverted (0.2%). Those baseline metrics tell you what to expect before you book.

Having 8 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,939 total flights analyzed, the 81% on-time figure is statistically meaningful rather than a small-sample fluke. The 63.1-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, Oct 2024 posted the best performance on this corridor at 98% on-time, while Dec 2025 came in at 65% on-time — a 34-point gap between best and worst recent month. For travelers evaluating the ORD to PSP route, the combination of a 81% on-time rate, 63.1-minute average delay, 0.5% recent cancellation rate, and 8 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
