SkyWest on MFE to IAH lands a B+, about a point worse than the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by about 2.9 hours on average. That rests on 328 flights, with a median arrival 9 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate SkyWest on MFE to IAH from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

The worst days
Worst days for SkyWest on MFE to IAH
The latest arrival of the period was on 9 July 2026, 21 hours 7 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across July, June, August and May, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 July 2026 | 21 hours 7 minutes | Carrier |
| 2 June 2026 | 19 hours 1 minute | National Airspace System |

Delay causes
Why SkyWest runs late on this route
Late-arriving aircraft accounts for 51% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Late-arriving aircraft
- 29%Carrier
- 17%National Airspace System
- 3%Extreme weather
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 15 to one. The split is drawn from 13,649 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 95.3% on time here.
Cancellations sit at 0.91% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
13.2% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
At 316 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.
The return leg runs 75.7% on time across 329 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 328 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking SkyWest on MFE to IAH
Put together: treat all of this as provisional. 328 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 76.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 325 completed flights over 12 months sit behind that.
