Anchorage to Chicago

What the Data Says About ANC to ORD

The Anchorage to Chicago corridor (ANC → ORD) covers roughly 2,846 miles and is served by 9 carriers, based on Bureau of Transportation Statistics reporting. Across 3,576 flights in the dataset, this route posts a 77.2% on-time rate with an average delay of 82.7 minutes when flights run late. Over the most recent 24 months of BTS data, 2,434 flights were recorded on this pairing — 17 cancelled (0.7%) and 13 diverted (0.5%). 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 3,576 total flights analyzed, the 77.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 82.7-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 93% on-time, while Jun 2023 came in at 59% on-time — a 34-point gap between best and worst recent month. For travelers evaluating the ANC to ORD route, the combination of a 77.2% on-time rate, 82.7-minute average delay, 0.7% recent cancellation rate, and 9 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
