Houston to Mission/McAllen/Edinburg

What the Data Says About IAH to MFE

The Houston to Mission/McAllen/Edinburg corridor (IAH → MFE) covers roughly 316 miles and is served by 16 carriers, based on Bureau of Transportation Statistics reporting. Across 5,811 flights in the dataset, this route posts a 83.2% on-time rate with an average delay of 77.1 minutes when flights run late. Over the most recent 24 months of BTS data, 1,518 flights were recorded on this pairing — 28 cancelled (1.8%) and 2 diverted (0.1%). Those baseline metrics tell you what to expect before you book.

Having 16 carriers on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 5,811 total flights analyzed, the 83.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 77.1-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 94% on-time, while Jul 2024 came in at 51% on-time — a 43-point gap between best and worst recent month. For travelers evaluating the IAH to MFE route, the combination of a 83.2% on-time rate, 77.1-minute average delay, 1.8% recent cancellation rate, and 16 available carriers is the concrete summary of what BTS data shows about reliability on this pairing.
