Across the year
DL 994 quarter by quarter
DL 994 did not run the same all year. Its best quarter was Apr–Jun 2026 at 82.7% on time and its weakest Jul–Sep 2026 at 66.1%, a swing of 17 points on roughly 83 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.

Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, DL 994 did best on Wednesday at 89.8% on time and worst on Sunday at 64.4%. Each day rests on about 47 flights, so a gap of 25 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 994 runs when it is late
DL 994 often beats the schedule: 111 of 322 completed flights, 34%, arrived 15 minutes or more early. The 69 late arrivals split 27 under half an hour, 16 between 30 and 60 minutes, and 26 an hour or more.

Share of 322 completed flights by arrival against schedule.
A late pushback is often recovered here: of 64 departures that left 15 minutes late or more, 20 still arrived on time. In the other direction, 25 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 994
The latest arrival of the period was on 21 July 2026, 7 hours 6 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across July, December and October, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 21 July 2026 | 7 hours 6 minutes | National Airspace System |
| 14 December 2025 | 6 hours 5 minutes | Carrier |

Delay causes
Why DL 994 runs late
National Airspace System accounts for 43% of the 4,260 delay minutes carriers reported here, and the remaining four split what is left.

- 0%Extreme weather
43% 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 1,813 minutes out of 4,260, against a national NAS share of 21%. The split is drawn from 4,260 delay minutes reported on DL 994.
Cancellations sit at 2.12% against a national 1.89%, which is ordinary. Diversions add another 0.30%.
Connections and routes
What a delay on this flight costs
8.1% of arrivals land an hour or more late, close to the national 8.3%, so 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 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.
The same number turns up on one other city pair in the data, including LAS to SLC (16), but none flew often enough under DL 994 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to ATL only.
One caution: this is a thin sample. 330 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 994
