Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2052, check with Delta Air Lines.

DL 2052 earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 364 flights, with a median arrival 6 minutes early.

Set against the rest of the country, DL 2052's record is 8 points better than the US average of 77.6%. That gap is worth roughly 76 fewer late arrivals for every thousand flights.

These figures cover 364 flights between July 2025 and June 2026. The median arrival is 6 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 2052 flies

DL 2052 flies ATL to RDU without a single fixed slot. Its most common scheduled departure was 10:15, used on 55 of 364 flights, with 21:15 (43 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 10:15 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 2052 runs level with that at 85.2%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 2052 next to ATL to RDU

Across the year

DL 2052 quarter by quarter

DL 2052 did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.3% on time and its weakest Jul–Sep 2025 at 75.0%, a swing of 19 points on roughly 91 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 202690 flights91.9%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 2052 ranged from 78.8% on Monday to 90.4% on Wednesday. With about 52 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 2052 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 44% of the 3,269 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
8%

44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,269 reported delay minutes here, that single category outweighs weather by 6 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,269 delay minutes reported on DL 2052.

Cancellations sit at 1.65% against a national 1.81%, which is ordinary. Diversions add another 0.27%.

Connections and routes

What a delay on this flight costs

5.0% 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.

The same number turns up on one other city pair in the data, including RDU to ATL (193), but none flew often enough under DL 2052 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to RDU only.

One caution: this is a thin sample. 364 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 2052

For a booking, read DL 2052 as 85.2% on time with 1.65% cancelled over 364 flights. Those are rates from the past twelve months, not a forecast for any particular day.
