This route lands a B, about a point 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 1,028 MSP to MCI flights, with a median arrival 6 minutes early.
Best time to fly MSP to MCI: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 81.7% of the time and Tuesday flights 85.3%, against 78.4% for the route overall.
The US average over the same twelve months is 77.6%, 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.

These figures cover 1,028 flights between July 2025 and June 2026. Beyond the headline rate, 8.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
Which airline is most reliable on MSP to MCI
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Flight by flight
Flights on MSP to MCI
The flight numbers below flew this route at least 250 times in the period, busiest first. Each has its own record, with its schedule and delay causes.
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 1,028 flights.
- 5am–8am72 flights81.7%
- 8am–11am183 flights80.1%
- 11am–2pm112 flights76.6%
- 2pm–5pm297 flights80.6%
- 5pm–8pm1 flights—
- 8pm–5am363 flights75.4%
Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.
The early departures do better, though not dramatically: 81.7% on time for the 5am–8am window against 75.4% for 8pm–5am. Worth taking if the schedule allows, not worth an extra connection. The 8pm–5am window is the busiest, with 363 flights scheduled in it.
Across the year
When delays peak on this route
This route's year swings by 27 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 62.5% on time, against 89.8% in April. 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. March was the busiest month here, with 115 flights.
Across the week, Tuesday is the strongest day at 85.3% on time and Friday the weakest at 73.6%. 12 points is a smaller lever than departure hour, but it is free.
Delay causes
Why this route gets delayed
One category carries most of the weight here. Carrier accounts for 65% of the 18,000 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.
- 65%Carrier
- 16%Late-arriving aircraft
- 9%Extreme weather
- 9%National Airspace System
The largest share of delay minutes, 65%, 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 12,000 of the 18,000 delay minutes reported here. The split is drawn from 17,773 reported delay minutes.
Cancellations sit at 1.46% against a national 1.81%, which is ordinary. Diversions add another 0.10%.
Connections and stage length
What a delay here actually costs
8.5% 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 393 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 82.3% on time across 1,028 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. 1,028 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. 1,028 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 78.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 1,012 completed flights over 12 months sit behind that.
Common questions
MSP to MCI questions
How often is MSP to MCI 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 21.6% of the 1,028 flights in this analysis, against 22.4% nationally. Delayed flights are late by a little over an hour on average.
How reliable is MSP to MCI compared with the rest of the country?
78.4% of flights arrive on time here against a national 77.6%, a difference of about a point 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 MCI?
The 5am–8am departure window is the strongest at 81.7% on time. The 8pm–5am window is the weakest at 75.4%, 6 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 MCI?
December is the weakest month at 62.5% on time, compared with 89.8% in April. Across the year that is 27 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
