These figures cover 265 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 2786 flies

DL 2786 flies ATL to CMH without a single fixed slot. Its most common scheduled departure was 17:05, used on 55 of 265 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 17:05 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2786 runs 7 points better at 75.6%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

DL 2786 next to ATL to CMH

Across the year

DL 2786 quarter by quarter

DL 2786 did not run the same all year. Its best quarter was Jan–Mar 2026 at 82.8% on time and its weakest Oct–Dec 2025 at 59.1%, a swing of 24 points on roughly 66 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.

Jan–Mar 202665 flights82.8%

Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2786 did best on Wednesday at 85.7% on time and worst on Tuesday at 66.7%. Each day rests on about 38 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2786 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,300 reported delay minutes.

Late-arriving aircraft
34%
Carrier
33%
National Airspace System
18%
Extreme weather
15%

Extreme weather accounts for 15% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.4 times the usual weather exposure. The split is drawn from 3,300 delay minutes reported on DL 2786.

Cancellations sit at 1.13% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

5.7% 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 roughly 50 minutes, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including CMH to ATL (90), but none flew often enough under DL 2786 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to CMH only.

One caution: this is a thin sample. 265 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 2786

For a booking, read DL 2786 as 75.6% on time with 1.13% cancelled over 265 flights. Those are rates from the past twelve months, not a forecast for any particular day.
