DL 2727 earns an A. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 17 points better than the national rate of 77.6%. When something does go wrong the average delay runs close to two hours. That rests on 349 flights, with a median arrival 19 minutes early.

Set against the rest of the country, DL 2727's record is 17 points better than the US average of 77.6%. That gap is worth roughly 168 fewer late arrivals for every thousand flights.

These figures cover 349 flights between July 2025 and June 2026. The median arrival is 19 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 2727 flies

DL 2727 flies DSM to ATL without a single fixed slot. Its most common scheduled departure was 05:35, used on 119 of 349 flights, with 05:44 (56 flights) and 05:30 (35 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 05:35 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 2727 runs 5 points better at 94.4%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

DL 2727 quarter by quarter

Quarter by quarter DL 2727 held fairly steady: 96.7% in Jul–Sep 2025, 93.3% in Oct–Dec 2025, 91.7% in Jan–Mar 2026 and 95.5% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2727 ranged from 87.2% on Saturday to 98.0% on Tuesday. With about 50 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2727 runs late

One category carries most of the weight here. Carrier accounts for 79% of the 2,065 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.

Carrier
79%
National Airspace System
11%
Extreme weather
10%

The largest share of delay minutes, 79%, 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 1,630 of the 2,065 delay minutes reported here. The split is drawn from 2,065 delay minutes reported on DL 2727.

Cancellations sit at 2.29% against a national 1.81%, which is ordinary. Diversions add another 0.57%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.2% 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 743 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 same number turns up on one other city pair in the data, including DFW to SLC (16), but none flew often enough under DL 2727 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DSM to ATL only.

One caution: this is a thin sample. 349 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 2727

For a booking, read DL 2727 as 94.4% on time with 2.29% cancelled over 349 flights. Those are rates from the past twelve months, not a forecast for any particular day.
