These figures cover 314 flights between July 2025 and June 2026. Beyond the headline rate, 8.5% 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 2047 flies

DL 2047 flies ATL to ROC without a single fixed slot. Its most common scheduled departure was 15:15, used on 119 of 314 flights, with 15:18 (49 flights) and 15:32 (34 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 15:15 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 2047 runs 3 points better at 75.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

DL 2047 quarter by quarter

DL 2047 did not run the same all year. Its best quarter was Apr–Jun 2026 at 87.1% on time and its weakest Jul–Sep 2025 at 65.4%, a swing of 22 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 Friday at 82.2% on time and worst on Sunday at 65.2%. Each day rests on about 45 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2047 runs late

One category carries most of the weight here. Carrier accounts for 63% of the 4,851 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.

Late-arriving aircraft
24%
National Airspace System
11%
Extreme weather
2%

The largest share of delay minutes, 63%, 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 3,063 of the 4,851 delay minutes reported here. The split is drawn from 4,851 delay minutes reported on DL 2047.

Cancellations sit at 1.91% against a national 1.81%, which is ordinary. Diversions add another 0.32%.

Connections and routes

What a delay on this flight costs

8.5% 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 about an hour, which a normal layover absorbs.

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.

DL 2047 is not only a ATL to ROC flight. It also flew ROC to ATL (314 flights, 76.5% 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. 314 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.
