This route earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.3%. When something does go wrong the average delay runs an hour and a half. That rests on 900 MEM to MSP flights, with a median arrival 11 minutes early.
Best time to fly MEM to MSP: a 5am–8am departure, ideally on a Sunday. Flights in that window arrived on time 93.2% of the time and Sunday flights 91.6%, against 86.5% for the route overall.
Set against the rest of the country, this route's record is 9 points better than the US average of 77.3%. That gap is worth roughly 92 fewer late arrivals for every thousand flights.

These figures cover 900 flights between September 2025 and August 2026. The median arrival is 11 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.

Book the early departure. Flights leaving between 5am–8am arrive on time 93.2% of the time, against 76.4% for the evening window. That is 17 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 364 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 23 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 74.6% on time, against 98.0% in February. 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. July was the busiest month here, with 89 flights.
Across the week, Sunday is the strongest day at 91.6% on time and Friday the weakest at 80.0%, a spread of 12 points.
Delay causes
Why this route gets delayed
Carrier accounts for 80% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 80%Carrier
- 14%Extreme weather
- 5%National Airspace System
- 0%Security
Extreme weather accounts for 14% 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 2.4 times the usual weather exposure. The split is drawn from 11,102 reported delay minutes.
The largest share of delay minutes, 80%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 8,888 of the 11,000 delay minutes reported here.
Cancellations sit at 1.11% against a national 1.89%, which is ordinary. Diversions add another 0.11%.
Connections and stage length
What a delay here actually costs
Badly late arrivals are rare here: only 4.9% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 700 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg is a different operation and performs like one: it runs 82.7% on time across 900 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. 900 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. 900 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 86.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 889 completed flights over 12 months sit behind that.
Common questions
MEM to MSP questions
How often is MEM to MSP delayed?
About one flight in seven arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 13.5% of the 900 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
How reliable is MEM to MSP compared with the rest of the country?
86.5% of flights arrive on time here against a national 77.3%, a difference of 9 points in its favour. That is worth a A on this site's grading scale.
What time of day has the fewest delays on MEM to MSP?
The 5am–8am departure window is the strongest at 93.2% on time. The 5pm–8pm window is the weakest at 76.4%, 17 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 MEM to MSP?
December is the weakest month at 74.6% on time, compared with 98.0% in February. Across the year that is 23 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
