Baton Rouge to Houston

What the Data Says About BTR to IAH

The Baton Rouge to Houston corridor (BTR → IAH) covers roughly 253 miles and is served by 14 carriers, based on Bureau of Transportation Statistics reporting. Across 2,148 flights in the dataset, this route posts a 86.4% on-time rate with an average delay of 89.4 minutes when flights run late. Over the most recent 24 months of BTS data, 1,237 flights were recorded on this pairing — 28 cancelled (2.3%) and 5 diverted (0.4%). Those baseline metrics tell you what to expect before you book.

Having 14 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,148 total flights analyzed, the 86.4% on-time figure is statistically meaningful rather than a small-sample fluke. The 89.4-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 2020 posted the best performance on this corridor at 98% on-time, while Jan 2024 came in at 72% on-time — a 26-point gap between best and worst recent month. For travelers evaluating the BTR to IAH route, the combination of a 86.4% on-time rate, 89.4-minute average delay, 2.3% recent cancellation rate, and 14 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
