These figures cover 358 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.

A 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 992 runs 2 points better at 86.0%. 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 992 quarter by quarter
DL 992 did not run the same all year. Its best quarter was Jan–Mar 2026 at 90.2% on time and its weakest Jul–Sep 2026 at 80.0%, a swing of 10 points on roughly 90 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.

- Oct–Dec 202591 flights82.6%
- Jan–Mar 202690 flights90.2%
- Apr–Jun 202689 flights87.6%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, DL 992 did best on Tuesday at 92.2% on time and worst on Sunday at 77.8%. Each day rests on about 51 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 992 runs when it is late
DL 992 often beats the schedule: 111 of 343 completed flights, 32%, arrived 15 minutes or more early. The 48 late arrivals split 21 under half an hour, 14 between 30 and 60 minutes, and 13 an hour or more.

Share of 343 completed flights by arrival against schedule.
4 of 29 late departures made up the time and arrived on time, 14% of them. In the other direction, 23 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ATL.
The worst days
Worst days for DL 992
The latest arrival of the period was on 2 January 2026, 10 hours 57 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 January 2026 | 10 hours 57 minutes | Carrier |
| 7 December 2025 | 3 hours 18 minutes | National Airspace System |
| 11 April 2026 | 3 hours 18 minutes | Carrier |
| 4 July 2026 | 2 hours 51 minutes | Carrier |
| 13 June 2026 | 2 hours 5 minutes | Carrier |
Delay causes
Why DL 992 runs late
Carrier accounts for 67% of the 3,016 delay minutes carriers reported here, and the remaining four split what is left.
- 67%Carrier
- 32%National Airspace System
- 1%Late-arriving aircraft
32% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 973 minutes out of 3,016, against a national NAS share of 21%. The split is drawn from 3,016 delay minutes reported on DL 992.
Cancellations run at 4.19%, 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 3.8% 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 358 flights under DL 992 in the data flew LGA to ATL. 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. 358 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 992
For a booking, the cancellation rate is the figure to plan around on DL 992: 4.19% of its 358 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
