When SkyWest runs best on this route

- 8am–11am196 flights89.7%
- 11am–2pm96 flights80.4%

Book the morning departure. Flights leaving between 8am–11am arrive on time 89.7% of the time, against 75.6% for the overnight window. That is 14 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 196 flights scheduled in it.
Across the year
SkyWest on MSP to BIS through the year
December is the weak month at 61.6% on time, against 97.0% 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. September was the busiest month here, with 106 flights.
Across the week, Sunday is the strongest day at 91.3% on time and Friday the weakest at 78.3%, a spread of 13 points.

Delay causes
Why SkyWest runs late on this route
Carrier accounts for 62% of the 5,825 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Carrier
- 18%Extreme weather
- 18%National Airspace System
- 2%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 3.1 times the usual weather exposure. The split is drawn from 5,825 reported delay minutes.
The largest share of delay minutes, 62%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,602 of the 5,825 delay minutes reported here.
Cancellations sit at 1.09% against a national 1.89%, which is ordinary. Diversions add another 0.16%.
Connections and stage length
What a delay here costs
5.7% 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 about an hour, which a normal layover absorbs.
At 386 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 85.4% on time across 641 flights, within 2 points 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. 641 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 BIS
Put together: treat all of this as provisional. 641 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 83.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 633 completed flights over 12 months sit behind that.
