These figures cover 595 flights between September 2025 and August 2026. The median arrival is 10 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 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.
- 5am–8am365 flights84.4%
- 8am–11am—
- 11am–2pm50 flights84.0%
- 2pm–5pm—
- 5pm–8pm105 flights70.2%
- 8pm–5am75 flights80.8%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 84.4% of the time, against 70.2% for the evening 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 5am–8am window is the busiest, with 365 flights scheduled in it.
Across the year
Delta on GRR to MSP through the year
January is the weak month at 48.4% on time, against 100.0% in May. 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, Monday is the strongest day at 86.5% on time and Friday the weakest at 76.7%, a spread of 10 points.

| 15 June 2026 | 13 hours 36 minutes | Carrier |

Delay causes
Why Delta runs late on this route
Carrier accounts for 56% of the 9,323 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Carrier
- 24%Late-arriving aircraft
- 12%National Airspace System
- 7%Extreme weather
The largest share of delay minutes, 56%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,265 of the 9,323 delay minutes reported here. The split is drawn from 9,323 reported delay minutes.
Cancellations sit at 1.34% against a national 1.89%, which is ordinary. Diversions add another 0.34%.
Connections and stage length
What a delay here costs
7.7% 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 an hour and a half, 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 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 77.0% on time across 595 flights, 4 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 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 GRR to MSP
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 81.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 585 completed flights over 12 months sit behind that.
