Across the year
DL 2472 quarter by quarter

Share of 352 completed flights by arrival against schedule.
12 of 84 late departures made up the time and arrived on time, 14% of them. In the other direction, 19 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ROC.
The worst days
Worst days for DL 2472
The latest arrival of the period was on 13 April 2026, 2 hours 43 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 13 April 2026 | 2 hours 43 minutes | Carrier |
| 10 July 2026 | 2 hours 40 minutes | Carrier |

Delay causes
Why DL 2472 runs late
Carrier accounts for 49% of the 4,810 delay minutes carriers reported here, and the remaining four split what is left.

- 29%Late-arriving aircraft
- 18%National Airspace System
- 3%Extreme weather
- 2%Security
The largest share of delay minutes, 49%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,339 of the 4,810 delay minutes reported here. The split is drawn from 4,810 delay minutes reported on DL 2472.
Cancellations run at 3.01%, against 1.89% nationally. That is roughly one flight in 30 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
9.1% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
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: 3.01% of its 365 scheduled flights did not operate. A late arrival costs roughly 55 minutes, but a cancellation costs the day, so leave a later option open.
