DL 2248 lands a B, about a point worse than the national rate of 77.6%. About one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 306 flights, with a median arrival 5 minutes early.

These figures cover 306 flights between July 2025 and June 2026. The median arrival is 5 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 2248 flies

DL 2248 flies ATL to CVG without a single fixed slot. Its most common scheduled departure was 18:35, used on 90 of 306 flights, with 17:32 (49 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 18:35 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2248 runs 8 points better at 76.3%. 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 2248 quarter by quarter

Quarter by quarter DL 2248 held fairly steady: 74.4% in Jul–Sep 2025, 79.3% in Oct–Dec 2025, 76.9% in Jan–Mar 2026 and 74.6% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202591 flights74.4%
Oct–Dec 202583 flights79.3%
Jan–Mar 202667 flights76.9%

Scale runs 65% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2248 did best on Wednesday at 88.6% on time and worst on Sunday at 66.0%. Each day rests on about 44 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2248 runs late

One category carries most of the weight here. Carrier accounts for 62% of the 3,920 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

National Airspace System
12%
Extreme weather
3%

The largest share of delay minutes, 62%, 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 2,444 of the 3,920 delay minutes reported here. The split is drawn from 3,920 delay minutes reported on DL 2248.

Cancellations sit at 1.63% against a national 1.81%, which is ordinary. Diversions add another 0.33%.

Connections and routes

What a delay on this flight costs

6.7% 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.

Every one of the 306 flights under DL 2248 in the data flew ATL to CVG. 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. 306 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 2248

For a booking, DL 2248 is one of the weaker ways to fly ATL to CVG: 6 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
