These figures cover 365 flights between July 2025 and June 2026. Beyond the headline rate, 9.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When DL 2472 flies
DL 2472 flies ATL to ROC without a single fixed slot. Its most common scheduled departure was 21:56, used on 60 of 365 flights, with 21:55 (45 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 21:5660 flights16.4%
- Departs 21:5545 flights12.3%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 21:56 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 2472 runs 4 points better at 74.9%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year
DL 2472 quarter by quarter
DL 2472 did not run the same all year. Its best quarter was Apr–Jun 2026 at 80.0% on time and its weakest Oct–Dec 2025 at 69.7%, a swing of 10 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
- Jul–Sep 202592 flights73.6%
- Oct–Dec 202592 flights69.7%
- Jan–Mar 202690 flights76.2%
- Apr–Jun 202691 flights80.0%
Scale runs 60% to 85%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2472 did best on Saturday at 87.8% on time and worst on Monday at 59.6%. Each day rests on about 52 flights, so a gap of 28 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 2472 runs late
One category carries most of the weight here. Carrier accounts for 43% of the 4,813 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.
- 43%Carrier
- 35%Late-arriving aircraft
- 15%National Airspace System
- 5%Extreme weather
- 2%Security
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,813 reported delay minutes here, that single category outweighs weather by 6 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,813 delay minutes reported on DL 2472.
Cancellations run at 3.84%, against 1.81% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.1% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 749 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 365 flights under DL 2472 in the data flew ATL to ROC. 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. 365 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 2472
For a booking, the cancellation rate is the figure to plan around on DL 2472: 3.84% of its 365 scheduled flights did not operate. A late arrival costs about 55 minutes, but a cancellation costs the day, so leave a later option open.
