Chicago to Newark

What the Data Says About ORD to EWR

The Chicago to Newark corridor (ORD → EWR) covers roughly 719 miles and is served by 34 carriers, based on Bureau of Transportation Statistics reporting. Across 29,547 flights in the dataset, this route posts a 74.4% on-time rate with an average delay of 80.5 minutes when flights run late. Over the most recent 24 months of BTS data, 12,098 flights were recorded on this pairing — 280 cancelled (2.3%) and 36 diverted (0.3%). Those baseline metrics tell you what to expect before you book.

Having 34 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 29,547 total flights analyzed, the 74.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 80.5-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, Feb 2024 posted the best performance on this corridor at 88% on-time, while May 2025 came in at 50% on-time — a 37-point gap between best and worst recent month. For travelers evaluating the ORD to EWR route, the combination of a 74.4% on-time rate, 80.5-minute average delay, 2.3% recent cancellation rate, and 34 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
