Across the year
DL 2498 quarter by quarter
DL 2498 did not run the same all year. Its best quarter was Apr–Jun 2026 at 73.3% on time and its weakest Jul–Sep 2026 at 32.2%, a swing of 41 points on roughly 88 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.

By weekday, DL 2498 did best on Saturday at 70.3% on time and worst on Thursday at 40.4%. Each day rests on about 50 flights, so a gap of 30 points is worth noticing but could still narrow in another year.

Share of 342 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 127 departures that left 15 minutes late or more, only 6 made it up before arrival. In the other direction, 37 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 EWR.

Delay causes
Why DL 2498 runs late
National Airspace System accounts for 56% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.
- 56%National Airspace System
- 24%Carrier
- 14%Late-arriving aircraft
- 5%Extreme weather
56% 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 7,303 minutes out of 13,000, against a national NAS share of 21%. The split is drawn from 12,939 delay minutes reported on DL 2498.
Cancellations run at 2.56%, against 1.89% nationally. That is about one flight in 40 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
21.1% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
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.
Every one of the 351 flights under DL 2498 in the data flew ATL to EWR. 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 2498
For a booking, the cancellation rate is the figure to plan around on DL 2498: 2.56% of its 351 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
