Chicago to Savannah

What the Data Says About ORD to SAV

The Chicago to Savannah corridor (ORD → SAV) covers roughly 773 miles and is served by 38 carriers, based on Bureau of Transportation Statistics reporting. Across 5,680 flights in the dataset, this route posts a 83% on-time rate with an average delay of 70.3 minutes when flights run late. Over the most recent 24 months of BTS data, 2,252 flights were recorded on this pairing — 29 cancelled (1.3%) and 7 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 38 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,680 total flights analyzed, the 83% on-time figure is statistically meaningful rather than a small-sample fluke. The 70.3-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, Nov 2024 posted the best performance on this corridor at 91% on-time, while Mar 2025 came in at 73% on-time — a 18-point gap between best and worst recent month. For travelers evaluating the ORD to SAV route, the combination of a 83% on-time rate, 70.3-minute average delay, 1.3% recent cancellation rate, and 38 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
