Houston to Newark

What the Data Says About IAH to EWR

The Houston to Newark corridor (IAH → EWR) covers roughly 1,400 miles and is served by 3 carriers, based on Bureau of Transportation Statistics reporting. Across 19,906 flights in the dataset, this route posts a 76.6% on-time rate with an average delay of 76.2 minutes when flights run late. Over the most recent 24 months of BTS data, 7,494 flights were recorded on this pairing — 143 cancelled (1.9%) and 43 diverted (0.6%). Those baseline metrics tell you what to expect before you book.

Having 3 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 19,906 total flights analyzed, the 76.6% on-time figure is statistically meaningful rather than a small-sample fluke. The 76.2-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, Jan 2025 posted the best performance on this corridor at 89% on-time, while Jul 2024 came in at 53% on-time — a 36-point gap between best and worst recent month. For travelers evaluating the IAH to EWR route, the combination of a 76.6% on-time rate, 76.2-minute average delay, 1.9% recent cancellation rate, and 3 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
