SkyWest on MEM to IAH lands a B+, about a point better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 723 flights, with a median arrival 8 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate SkyWest on MEM to IAH from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Departure window
When SkyWest runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 16 points, against half a point between the best and worst carrier.

- 8am–11am67 flights89.6%
- 11am–2pm342 flights81.1%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 89.6% of the time, against 73.6% for the afternoon window. That is 16 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 342 flights scheduled in it.
Across the year
SkyWest on MEM to IAH through the year
December is the weak month at 61.7% on time, against 92.9% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. April was the busiest month here, with 89 flights.
Across the week, Tuesday is the strongest day at 84.1% on time and Sunday the weakest at 75.0%, a spread of 9 points.

The worst days
Worst days for SkyWest on MEM to IAH
The latest arrival of the period was on 1 December 2025, 20 hours 53 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across December, March and April, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 1 December 2025 | 20 hours 53 minutes | Carrier |
| 16 March 2026 | 8 hours 14 minutes | National Airspace System |

Delay causes
Why SkyWest runs late on this route
Late-arriving aircraft accounts for 42% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 42%Late-arriving aircraft
- 25%Carrier
- 23%National Airspace System
- 10%Extreme weather
42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 13,000 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 13,110 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 89.6% on time here.
Cancellations are rare at 0.83%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here costs
8.9% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
At 468 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 8am–11am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 84.7% on time across 719 flights, 6 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 6 points of difference.
One caution: this is a thin sample. 723 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 MEM to IAH
Put together: treat all of this as provisional. 723 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 78.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 716 completed flights over 12 months sit behind that.
