DL 2600 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 about 55 minutes on average. That is a workable record, not a spotless one. That rests on 302 flights, with a median arrival 1 minute early.

These figures cover 302 flights between July 2025 and June 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Schedule

When DL 2600 flies

DL 2600 flies ATL to RDU without a single fixed slot. Its most common scheduled departure was 15:55, used on 31 of 302 flights, with 16:00 (31 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 15:55 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 2600 runs 8 points better at 79.9%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

DL 2600 next to ATL to RDU

Across the year

DL 2600 quarter by quarter

DL 2600 did not run the same all year. Its best quarter was Oct–Dec 2025 at 86.4% on time and its weakest Apr–Jun 2026 at 75.6%, a swing of 11 points on roughly 76 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 2600 did best on Wednesday at 93.2% on time and worst on Monday at 73.9%. Each day rests on about 43 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 2600 runs late

One category carries most of the weight here. Carrier accounts for 45% of the 3,293 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.

Extreme weather
4%

The largest share of delay minutes, 45%, 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 1,468 of the 3,293 delay minutes reported here. The split is drawn from 3,293 delay minutes reported on DL 2600.

Cancellations are rare at 0.33%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

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 about 55 minutes, which a normal layover absorbs.

DL 2600 is not only a ATL to RDU flight. It also flew RDU to ATL (251 flights, 82.7% 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. 302 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.
