DL 513 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 10 points better than the national rate of 77.3%. When something does go wrong the average delay runs about 45 minutes. That rests on 351 flights, with a median arrival 8 minutes early.
Set against the rest of the country, DL 513's record is 10 points better than the US average of 77.3%. That gap is worth roughly 104 fewer late arrivals for every thousand flights.

These figures cover 351 flights between September 2025 and August 2026. The median arrival is 8 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 513 flies
DL 513 is scheduled to leave Atlanta (ATL) at 08:30 local time and reach New York (LGA) at 10:41. That slot held for 334 of the 351 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

A 08:30 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 513 runs 4 points better at 87.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
DL 513 quarter by quarter
Quarter by quarter DL 513 held fairly steady: 85.4% in Oct–Dec 2025, 86.4% in Jan–Mar 2026, 90.0% in Apr–Jun 2026 and 86.2% in Jul–Sep 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202526 flights—
- Oct–Dec 202591 flights85.4%
- Jan–Mar 202690 flights86.4%
- Apr–Jun 202682 flights90.0%
- Jul–Sep 202662 flights86.2%
Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, DL 513 did best on Wednesday at 94.0% on time and worst on Saturday at 79.5%. Each day rests on about 50 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 513
The latest arrival of the period was on 14 December 2025, 4 hours 19 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across December, April, January and November, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 December 2025 | 4 hours 19 minutes | Extreme weather |
| 5 April 2026 | 3 hours 23 minutes | Carrier |
| 28 January 2026 | 1 hour 14 minutes | Carrier |

Delay causes
Why DL 513 runs late
Carrier accounts for 44% of the 1,809 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Carrier
- 38%National Airspace System
- 14%Extreme weather
- 4%Late-arriving aircraft
Extreme weather accounts for 14% 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 2.3 times the usual weather exposure. The split is drawn from 1,809 delay minutes reported on DL 513.
Cancellations run at 4.27%, against 1.89% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.8% land an hour or more behind schedule, against 8.3% 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 762 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
Every one of the 351 flights under DL 513 in the data flew ATL to LGA. 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. 351 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 513
For a booking, the cancellation rate is the figure to plan around on DL 513: 4.27% of its 351 scheduled flights did not operate. A late arrival costs about 45 minutes, but a cancellation costs the day, so leave a later option open.
