Delta on MSP to GRR lands a B, level with the national rate of 77.3%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 595 flights, with a median arrival 6 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Delta on MSP to GRR from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Departure window
When Delta runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 14 points, against half a point between the best and worst carrier.

- 8am–11am50 flights88.0%
- 11am–2pm2 flights—

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 88.0% of the time, against 73.8% 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 8pm–5am window is the busiest, with 345 flights scheduled in it.
Across the year
Delta on MSP to GRR through the year
December is the weak month at 63.0% on time, against 89.1% in November. 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. June was the busiest month here, with 90 flights.
Across the week, Wednesday is the strongest day at 82.4% on time and Thursday the weakest at 69.8%, a spread of 13 points.

Delay causes
Why Delta runs late on this route
Carrier accounts for 58% of the 8,418 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Carrier
- 23%Late-arriving aircraft
- 17%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 58%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,870 of the 8,418 delay minutes reported here. The split is drawn from 8,418 reported delay minutes.
Cancellations sit at 1.01% against a national 1.89%, which is ordinary. Diversions add another 0.34%.
Connections and stage length
What a delay here costs
8.3% 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 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 is a different operation and performs like one: it runs 81.4% on time across 595 flights, 4 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 4 points of difference.
One caution: this is a thin sample. 595 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 Delta on MSP to GRR
Put together: treat all of this as provisional. 595 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 77.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 587 completed flights over 12 months sit behind that.
