SkyWest on DTW to CMH 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 close to two hours on average. That rests on 587 flights, with a median arrival 8 minutes early.

When SkyWest runs best on this route

Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 59.8% on time, against 85.7% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 233 flights scheduled in it.
Across the year
SkyWest on DTW to CMH through the year
December is the weak month at 51.0% on time, against 93.6% in October. 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. February was the busiest month here, with 72 flights.
Across the week, Saturday is the strongest day at 88.7% on time and Sunday the weakest at 68.2%, a spread of 21 points.

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 78% of the 15,000 delay minutes carriers reported here, and the remaining four split what is left.
- 78%Carrier
- 16%Extreme weather
- 5%National Airspace System
Extreme weather accounts for 16% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.7 times the usual weather exposure. The split is drawn from 15,433 reported delay minutes.
The largest share of delay minutes, 78%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 12,000 of the 15,000 delay minutes reported here.
Cancellations sit at 1.53% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
12.1% 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 155 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 79.4% on time across 587 flights, 3 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 3 points of difference.
One caution: this is a thin sample. 587 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 DTW to CMH
Put together: treat all of this as provisional. 587 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. 578 completed flights over 12 months sit behind that.
