Across the year
DL 2047 quarter by quarter
DL 2047 did not run the same all year. Its best quarter was Jan–Mar 2026 at 84.3% on time and its weakest Jul–Sep 2026 at 59.3%, a swing of 25 points on roughly 79 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.

By weekday, DL 2047 did best on Wednesday at 83.0% on time and worst on Sunday at 65.2%. Each day rests on about 45 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

The latest arrival of the period was on 28 December 2025, 6 hours 37 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across December, August, November, January and June, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 December 2025 | 6 hours 37 minutes | Carrier |
| 23 August 2026 | 4 hours 50 minutes | Carrier |
| 9 November 2025 | 4 hours 48 minutes | Extreme weather |

Delay causes
Why DL 2047 runs late
Late-arriving aircraft accounts for 59% of the 6,021 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Late-arriving aircraft
- 18%Carrier
- 15%National Airspace System
- 8%Extreme weather
59% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,021 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 6,021 delay minutes reported on DL 2047.
Cancellations sit at 1.89% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
12.2% 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.
DL 2047 is not only a ROC to ATL flight. It also flew ATL to ROC (317 flights, 75.9% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 317 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 2047
For a booking, DL 2047 is a flight to put a long connection behind. 12.2% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
