DL 3052 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 254 flights, with a median arrival 16 minutes early.

Set against the rest of the country, DL 3052's record is 12 points better than the US average of 77.6%. That gap is worth roughly 115 fewer late arrivals for every thousand flights.

These figures cover 254 flights between July 2025 and June 2026. The median arrival is 16 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 3052 flies

DL 3052 flies GSO to ATL without a single fixed slot. Its most common scheduled departure was 12:20, used on 31 of 254 flights. 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 12:20 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and DL 3052 runs 10 points better at 89.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

DL 3052 next to GSO to ATL

Across the year

DL 3052 quarter by quarter

DL 3052 did not run the same all year. Its best quarter was Jan–Mar 2026 at 94.7% on time and its weakest Apr–Jun 2026 at 82.2%, a swing of 13 points on roughly 85 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 3052 did best on Tuesday at 95.0% on time and worst on Sunday at 80.6%. Each day rests on about 36 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 3052 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 81% of the 1,686 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.

81%

12%

81% 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 1,686 reported delay minutes here, that single category outweighs weather by 81 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 1,686 delay minutes reported on DL 3052.

Cancellations sit at 2.36% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.4% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The same number turns up on one other city pair in the data, including ATL to GSO (154), but none flew often enough under DL 3052 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to GSO to ATL only.

One caution: this is a thin sample. 254 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 3052

For a booking, read DL 3052 as 89.1% on time with 2.36% cancelled over 254 flights. Those are rates from the past twelve months, not a forecast for any particular day.
