DL 2372 lands a B, 4 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 7 minutes early.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 7 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 2372 flies

DL 2372 flies ATL to ROA without a single fixed slot. Its most common scheduled departure was 23:05, used on 118 of 365 flights, with 22:45 (52 flights) and 22:41 (49 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

A 23:05 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 2372 runs 11 points better at 81.4%. 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 2372 quarter by quarter

Quarter by quarter DL 2372 held fairly steady: 76.7% in Jul–Sep 2025, 83.1% in Oct–Dec 2025, 83.7% in Jan–Mar 2026 and 82.0% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Oct–Dec 202592 flights83.1%
Jan–Mar 202690 flights83.7%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2372 ranged from 75.0% on Sunday to 86.0% on Tuesday. With about 52 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 2372 runs late

One category carries most of the weight here. Carrier accounts for 74% of the 5,304 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
74%
Late-arriving aircraft
16%
National Airspace System
8%
Extreme weather
3%

The largest share of delay minutes, 74%, 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 3,916 of the 5,304 delay minutes reported here. The split is drawn from 5,304 delay minutes reported on DL 2372.

Cancellations sit at 2.47% against a national 1.81%, which is ordinary. Diversions add another 0.55%.

Connections and routes

What a delay on this flight costs

6.5% 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 a little over an hour, which a normal layover absorbs.

Every one of the 365 flights under DL 2372 in the data flew ATL to ROA. 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 2372

For a booking, read DL 2372 as 81.4% on time with 2.47% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
