Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with SkyWest Airlines.
SkyWest on MSP to GRR lands a B+, 4 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 652 flights, with a median arrival 9 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate SkyWest on MSP to GRR from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on MSP to GRR, 1,243 flights
These figures cover 652 flights between July 2025 and June 2026. The median arrival is 9 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.
Carrier by carrier
SkyWest against every carrier on MSP to GRR
SkyWest flew 652 of the 1,243 flights on MSP to GRR, most of the route. Its 81.1% on time is 2 points better than the route as a whole, which runs 79.6%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from SkyWest at 81.1% to Delta at 77.9%.

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 652 flights.
- 5am–8am—
- 8am–11am258 flights84.7%
- 11am–2pm289 flights78.5%
- 2pm–5pm104 flights79.4%
- 5pm–8pm1 flights—
- 8pm–5am—
Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 78.5% on time against 84.7% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 11am–2pm window is the busiest, with 289 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 88.6% 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. May was the busiest month here, with 84 flights.
Across the week, Tuesday is the strongest day at 89.7% on time and Thursday the weakest at 76.3%. 13 points is a smaller lever than departure hour, but it is free.
Delay causes
Why SkyWest runs late on this route
One category carries most of the weight here. Carrier accounts for 71% of the 8,928 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 71%Carrier
- 19%Extreme weather
- 10%National Airspace System
- 0%Security
Extreme weather accounts for 19% 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 8,928 reported delay minutes.
The largest share of delay minutes, 71%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 6,338 of the 8,928 delay minutes reported here.
Cancellations sit at 0.92% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
7.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 79.9% on time across 652 flights, within about 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. 652 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. 652 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 81.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 646 completed flights over 12 months sit behind that.
