DL 2401 earns a B−. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.3%. When something does go wrong the average delay runs roughly 45 minutes. That rests on 253 flights, with a median arrival 4 minutes early.
Set against the rest of the country, DL 2401's record is 7 points better than the US average of 77.3%. That gap is worth roughly 67 fewer late arrivals for every thousand flights.

These figures cover 253 flights between September 2025 and August 2026. The median arrival is 4 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 2401 flies
DL 2401 flies ATL to EWR without a single fixed slot. Its most common scheduled departure was 10:05, used on 59 of 253 flights, with 10:50 (38 flights) and 10:00 (36 flights) next.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 10:05 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 2401 runs level with that at 84.0%. 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 2401 quarter by quarter
DL 2401 did not run the same all year. Its best quarter was Apr–Jun 2026 at 92.0% on time and its weakest Jul–Sep 2026 at 75.4%, a swing of 17 points on roughly 84 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 202512 flights—
- Jan–Mar 202689 flights83.9%
- Apr–Jun 202691 flights92.0%
- Jul–Sep 202661 flights75.4%
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2401 did best on Wednesday at 94.4% on time and worst on Monday at 71.4%. Each day rests on about 36 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 2401
The latest arrival of the period was on 26 March 2026, 2 hours 26 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 26 March 2026 | 2 hours 26 minutes | Carrier |
| 18 March 2026 | 2 hours 17 minutes | Carrier |
| 1 June 2026 | 2 hours 6 minutes | Carrier |

Delay causes
Why DL 2401 runs late
Carrier accounts for 57% of the 1,838 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Carrier
- 27%National Airspace System
- 11%Late-arriving aircraft
- 4%Extreme weather
The largest share of delay minutes, 57%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,056 of the 1,838 delay minutes reported here. The split is drawn from 1,838 delay minutes reported on DL 2401.
Cancellations run at 3.16%, against 1.89% nationally. That is about one flight in 30 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 4.5% 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 746 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 three other city pairs in the data, including EWR to ATL (230), PVD to DTW (18) and DTW to PVD (18), but none flew often enough under DL 2401 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to EWR only.
One caution: this is a thin sample. 253 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 2401
For a booking, the cancellation rate is the figure to plan around on DL 2401: 3.16% of its 253 scheduled flights did not operate. A late arrival costs roughly 45 minutes, but a cancellation costs the day, so leave a later option open.
