DL 1144 lands a B, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average. That is a workable record, not a spotless one. That rests on 363 flights, with a median arrival 7 minutes early.

These figures cover 363 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.

Schedule

When DL 1144 flies

DL 1144 flies MSP to BNA without a single fixed slot. Its most common scheduled departure was 20:30, used on 63 of 363 flights, with 19:45 (62 flights) and 20:45 (60 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 20:30 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 1144 runs 7 points better at 77.0%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

Across the year

DL 1144 quarter by quarter

Quarter by quarter DL 1144 held fairly steady: 78.3% in Jul–Sep 2025, 72.4% in Oct–Dec 2025, 76.7% in Jan–Mar 2026 and 80.2% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Oct–Dec 202590 flights72.4%
Jan–Mar 202690 flights76.7%

Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1144 did best on Wednesday at 86.3% on time and worst on Friday at 66.7%. Each day rests on about 52 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 1144 runs late

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 3,845 reported delay minutes.

Carrier
39%
National Airspace System
30%
Late-arriving aircraft
27%
Extreme weather
4%

The largest share of delay minutes, 39%, 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 1,507 of the 3,845 delay minutes reported here. The split is drawn from 3,845 delay minutes reported on DL 1144.

Cancellations sit at 1.93% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

5.9% 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 roughly 45 minutes, which a normal layover absorbs.

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.

Every one of the 363 flights under DL 1144 in the data flew MSP to BNA. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 363 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 DL 1144

For a booking, read DL 1144 as 77.0% on time with 1.93% cancelled over 363 flights. Those are rates from the past twelve months, not a forecast for any particular day.
