These figures cover 658 flights between September 2025 and August 2026. The median arrival is 8 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Departure window
When SkyWest runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 658 flights.
- 5am–8am—
- 8am–11am270 flights84.6%
- 11am–2pm283 flights80.1%
- 2pm–5pm105 flights78.6%
- 5pm–8pm—
- 8pm–5am—
Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 84.6% on time for the 8am–11am window against 78.6% for 2pm–5pm. Worth taking if the schedule allows, not worth an extra connection. The 11am–2pm window is the busiest, with 283 flights scheduled in it.
Across the year
SkyWest on MSP to GRR through the year
January is the weak month at 69.4% on time, against 90.3% in August. 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. May was the busiest month here, with 84 flights.
Across the week, Tuesday is the strongest day at 91.7% on time and Thursday the weakest at 76.3%, a spread of 15 points.

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 73% of the 8,609 delay minutes carriers reported here, and the remaining four split what is left.
- 73%Carrier
- 18%Extreme weather
- 9%National Airspace System
- 0%Security
Extreme weather accounts for 18% 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 3.0 times the usual weather exposure. The split is drawn from 8,609 reported delay minutes.
The largest share of delay minutes, 73%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 6,265 of the 8,609 delay minutes reported here.
Cancellations sit at 1.06% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
7.4% 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 a little over an hour, which a normal layover absorbs.
At 408 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 runs 81.1% on time across 658 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. 658 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 MSP to GRR
Put together: treat all of this as provisional. 658 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 81.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 651 completed flights over 12 months sit behind that.
