This route lands a B, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 1,215 MSP to RSW flights, with a median arrival 6 minutes early.
Best time to fly MSP to RSW: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 86.2% of the time and Tuesday flights 85.9%, against 77.8% 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 1,215 flights between July 2025 and June 2026. The median arrival is 6 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
Which airline is most reliable on MSP to RSW
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.

Flights on MSP to RSW
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 matters more here than the choice of carrier. The gap between the best and worst window is 21 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

- 8am–11am381 flights82.1%
- 11am–2pm294 flights77.4%
- 2pm–5pm62 flights65.0%
- 5pm–8pm338 flights72.0%
- 8pm–5am—
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 86.2% of the time, against 65.0% for the afternoon window. That is 21 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 381 flights scheduled in it.
Across the year
When delays peak on this route
This route's year swings by 17 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 69.7% on time, against 87.0% in August. 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 158 flights.
Across the week, Tuesday is the strongest day at 85.9% on time and Saturday the weakest at 71.6%. 14 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 60% 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.
- 60%Carrier
- 24%National Airspace System
- 15%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 60%, 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 11,000 of the 18,000 delay minutes reported here. The split is drawn from 18,014 reported delay minutes.
Cancellations sit at 1.15% against a national 1.81%, which is ordinary. Diversions add another 0.33%.
Connections and stage length
What a delay here actually costs
7.3% 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 about an hour, which a normal layover absorbs.
The 1,416 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg runs 80.6% on time across 1,215 flights, within 3 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 1,215 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. August runs 87.0% on time and December 69.7%, a swing of 17 points. If the dates move at all, move them out of December before you think about anything else. 1,197 completed flights over 12 months sit behind that.
Common questions
MSP to RSW questions
How often is MSP to RSW delayed?
Roughly 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 22.2% of the 1,215 flights in this analysis, against 22.4% nationally. Delayed flights are late by about an hour on average.
How reliable is MSP to RSW compared with the rest of the country?
77.8% of flights arrive on time here against a national 77.6%, a difference of half 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 RSW?
The 5am–8am departure window is the strongest at 86.2% on time. The 2pm–5pm window is the weakest at 65.0%, 21 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 RSW?
December is the weakest month at 69.7% on time, compared with 87.0% in August. Across the year that is 17 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
