Historical statistics for July 2025 to June 2026, not live status. For today’s DL 513, check with Delta Air Lines.
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 11 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 45 minutes. That rests on 347 flights, with a median arrival 9 minutes early.
Set against the rest of the country, DL 513's record is 11 points better than the US average of 77.6%. That gap is worth roughly 110 fewer late arrivals for every thousand flights.

These figures cover 347 flights between July 2025 and June 2026. The median arrival is 9 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 10:48. That slot held for 331 of the 347 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 08:30 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 513 runs 5 points better at 88.6%. 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 513 next to ATL to LGA
Every carrier on ATL to LGA combined arrived on time 73.4% of the time across 8,344 flights, so DL 513 is 15 points ahead of it. Delta flew 4,936 flights on the same city pair under all its flight numbers, including this one, and those ran 76.7% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 7 points.

Across the year
DL 513 quarter by quarter
Quarter by quarter DL 513 held fairly steady: 92.8% in Jul–Sep 2025, 85.4% in Oct–Dec 2025, 86.4% in Jan–Mar 2026 and 90.0% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202584 flights92.8%
- Oct–Dec 202591 flights85.4%
- Jan–Mar 202690 flights86.4%
- Apr–Jun 202682 flights90.0%
Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 513 ranged from 83.3% on Saturday to 94.0% on Wednesday. With about 50 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why DL 513 runs late
One category carries most of the weight here. Carrier accounts for 44% of the 1,775 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.
- 44%Carrier
- 33%National Airspace System
- 14%Extreme weather
- 9%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 1,775 delay minutes reported on DL 513.
Cancellations run at 4.03%, against 1.81% 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 8.1% 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 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on one other city pair in the data, including BOS to BNA (1), but none flew often enough under DL 513 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to LGA only.
One caution: this is a thin sample. 347 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: 4.03% of its 347 scheduled flights did not operate. A late arrival costs roughly 45 minutes, but a cancellation costs the day, so leave a later option open.
