This route lands a B, 4 points better than the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about 50 minutes on average. That is a workable record, not a spotless one. That rests on 1,723 MSP to BNA flights, of which Delta Air Lines flew 1,213 at 82.6% on time.

Best time to fly MSP to BNA: a 5am–8am departure, ideally on a Tuesday. Flights in that window arrived on time 91.0% of the time and Tuesday flights 88.2%, against 81.5% 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 1,723 flights between July 2025 and June 2026. The median arrival is 7 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 BNA

The two carriers here are closely matched: 4 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

Best ways to make this trip

The most reliable ways to fly Minneapolis to Nashville

Every airline on this route, ranked by how often a scheduled flight actually operated and arrived on time, with its best departure time and most punctual flight number. No nearby airport pair beat these.

Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.

Plan this trip by month, day and time

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 24 points, against 4 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am545 flights91.0%
  • 8am–11am22 flights
  • 11am–2pm294 flights87.3%
  • 2pm–5pm419 flights74.4%
  • 5pm–8pm142 flights67.2%
  • 8pm–5am301 flights75.4%

Scale runs 60% to 95%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 91.0% of the time, against 67.2% for the evening window. That is 24 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 545 flights scheduled in it.

Across the year

When delays peak on this route

This route's year swings by 20 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.

On-time rate by calendar month82J89F74M85A82M75J77J89A91S84O83N71D
Darker means more delays. Figures are on-time percentages.September best, December worst

December is the weak month at 70.7% on time, against 90.8% in September. 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 172 flights.

Across the week, Tuesday is the strongest day at 88.2% on time and Friday the weakest at 76.4%. 12 points is a smaller lever than departure hour, but it is free.

Delay causes

Why this route gets delayed

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 16,000 reported delay minutes.

  • Carrier
    36%
  • National Airspace System
    30%
  • Late-arriving aircraft
    30%
  • Extreme weather
    3%
  • Security
    0%

The largest share of delay minutes, 36%, 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 5,759 of the 16,000 delay minutes reported here. The split is drawn from 15,879 reported delay minutes.

The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 91.0% on time here.

Cancellations sit at 1.39% against a national 1.81%, which is ordinary. Diversions add another 0.29%.

Connections and stage length

What a delay here actually costs

Badly late arrivals are rare here: only 4.4% land an hour or more behind schedule, against 8.1% 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 695 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 83.3% on time across 1,721 flights, within 2 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 1,723 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. September runs 90.8% on time and December 70.7%, a swing of 20 points. If the dates move at all, move them out of December before you think about anything else. 1,694 completed flights over 12 months sit behind that.

Common questions

MSP to BNA questions

How often is MSP to BNA 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 18.5% of the 1,723 flights in this analysis, against 22.4% nationally. Delayed flights are late by about 50 minutes on average.

Which airline is most reliable on MSP to BNA?

Delta Air Lines leads at 82.6% on time across 1,213 flights. Southwest Airlines is at the other end on 78.9%, a gap of 4 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.

What time of day has the fewest delays on MSP to BNA?

The 5am–8am departure window is the strongest at 91.0% on time. The 5pm–8pm window is the weakest at 67.2%, 24 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 BNA?

December is the weakest month at 70.7% on time, compared with 90.8% in September. Across the year that is 20 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
