DL 3029 lands a B, 2 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 an hour and a half on average. That is a workable record, not a spotless one. That rests on 310 flights, with a median arrival 7 minutes early.

These figures cover 310 flights between July 2025 and June 2026. Beyond the headline rate, 8.6% 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 3029 flies

DL 3029 flies ATL to CAE without a single fixed slot. Its most common scheduled departure was 22:50, used on 41 of 310 flights, with 22:30 (38 flights) and 22:54 (37 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 22:50 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 3029 runs 9 points better at 79.9%. 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 3029 quarter by quarter

DL 3029 did not run the same all year. Its best quarter was Apr–Jun 2026 at 85.2% on time and its weakest Jul–Sep 2025 at 75.0%, a swing of 10 points on roughly 78 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.

Jul–Sep 202592 flights75.0%
Oct–Dec 202566 flights76.9%
Jan–Mar 202662 flights83.1%
Apr–Jun 202690 flights85.2%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 3029 did best on Saturday at 95.1% on time and worst on Sunday at 73.2%. Each day rests on about 44 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 3029 runs late

One category carries most of the weight here. Carrier accounts for 55% of the 5,131 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
55%
Late-arriving aircraft
26%
Extreme weather
13%
National Airspace System
7%

Extreme weather accounts for 13% 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 2.0 times the usual weather exposure. The split is drawn from 5,131 delay minutes reported on DL 3029.

Cancellations sit at 1.94% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

8.6% 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 an hour and a half, which a normal layover absorbs.

Every one of the 310 flights under DL 3029 in the data flew ATL to CAE. 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. 310 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 3029

For a booking, read DL 3029 as 79.9% on time with 1.94% cancelled over 310 flights. Those are rates from the past twelve months, not a forecast for any particular day.
