What the record says about this route
Which airline you fly changes the odds here. United Airlines arrived on time 10.3 points more often than SkyWest Airlines over the same period on the same route — same airports, same weather, same air traffic control. A gap that survives all of that is about how the two airlines are run.
The season swings this route hard. In February it ran 33.1 points more punctual than in May — a difference bigger than the one between the best and worst airlines on most routes. If the date is flexible, it is worth more than the carrier.
The shape of the lateness matters here. Flights on this route are not late often, but when they are late they are late by about 97 minutes — long enough to lose a connection or an evening. The on-time percentage looks reassuring and understates the consequence of being on the wrong flight.
The route has been getting worse. The later months run 11.8 points less punctual than the earlier ones. A drift of that size is rarely weather; it is more often an airline adding frequencies faster than the airports can absorb them.
Which airline should you fly on this route?
Over January 2025 – August 2026, United Airlines arrived on time most often on MFE to IAH. SkyWest Airlines was late most often. Flights ran closest to schedule in February and worst in May.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on MFE to IAH during January 2025 – August 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.
A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.
Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
