This route lands a B, 2 points 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 close to two hours on average. That rests on 864 MSP to ATW flights, with a median arrival 9 minutes early.
Best time to fly MSP to ATW: a 8am–11am departure, ideally on a Saturday. Flights in that window arrived on time 82.3% of the time and Saturday flights 84.2%, against 78.9% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

The most reliable ways to fly Minneapolis to Appleton
Every airline on this route and on the routes between nearby airports, ranked by how often a scheduled flight actually operated and arrived on time. 1 of the top 2 use a different airport at one end.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. MSP → GRBMinneapolis to Green Bay | SkyWest Airlines | 79.0% | 80.1% | 1.43% | 8pm–5am, Sat (route) | — |

Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
Departure window
The best time of day to leave
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 864 flights.

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 82.3% on time for the 8am–11am window against 74.8% for 2pm–5pm. Worth taking if the schedule allows, not worth an extra connection. The 2pm–5pm window is the busiest, with 305 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 42 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
December is the weak month at 52.5% on time, against 94.6% 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. October was the busiest month here, with 93 flights.
Across the week, Saturday is the strongest day at 84.2% on time and Friday the weakest at 76.0%, a spread of 8 points.
Delay causes
Why this route gets delayed
Carrier accounts for 76% of the 19,000 delay minutes carriers reported here, and the remaining four split what is left.
- 76%Carrier
- 18%Extreme weather
- 6%National Airspace System
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 2.9 times the usual weather exposure. The split is drawn from 19,257 reported delay minutes.
The largest share of delay minutes, 76%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 15,000 of the 19,000 delay minutes reported here.
Cancellations sit at 1.85% against a national 1.89%, which is ordinary. Diversions add another 0.46%.
Connections and stage length
What a delay here actually costs
10.2% 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 236 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 74.4% on time across 866 flights, 5 points below 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 5 points of difference.
One caution: this is a thin sample. 864 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 this route
Put together: treat all of this as provisional. 864 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 78.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 844 completed flights over 12 months sit behind that.
Common questions
MSP to ATW questions
How often is MSP to ATW delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 21.1% of the 864 flights in this analysis, against 22.7% nationally. Delayed flights are late by close to two hours on average.
How reliable is MSP to ATW compared with the rest of the country?
78.9% of flights arrive on time here against a national 77.3%, a difference of 2 points in its favour. That is worth a B on this site's grading scale.
What time of day has the fewest delays on MSP to ATW?
The 8am–11am departure window is the strongest at 82.3% on time. The 2pm–5pm window is the weakest at 74.8%, 8 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are December delays on MSP to ATW?
December is the weakest month at 52.5% on time, compared with 94.6% in October. Across the year that is 42 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
