These figures cover 332 flights between September 2025 and August 2026. The median arrival is 3 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.

Across the year
DL 2590 quarter by quarter
DL 2590 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.7% on time and its weakest Jul–Sep 2026 at 53.1%, a swing of 44 points on roughly 66 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 2590 did best on Wednesday at 95.7% on time and worst on Sunday at 56.8%. Each day rests on about 47 flights, so a gap of 39 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 2590
The latest arrival of the period was on 29 December 2025, 2 hours 23 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 29 December 2025 | 2 hours 23 minutes | Carrier |
| 19 May 2026 | 2 hours 7 minutes | Carrier |
| 17 July 2026 | 1 hour 59 minutes | Carrier |

Delay causes
Why DL 2590 runs late
Carrier accounts for 58% of the 3,226 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Carrier
- 26%Late-arriving aircraft
- 11%National Airspace System
- 4%Extreme weather
The largest share of delay minutes, 58%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,881 of the 3,226 delay minutes reported here. The split is drawn from 3,226 delay minutes reported on DL 2590.
Cancellations run at 3.61%, 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
6.6% 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 roughly 50 minutes, which a normal layover absorbs.
The 577 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 LAX to PHX (1), but none flew often enough under DL 2590 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ATL to BWI only.
One caution: this is a thin sample. 332 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 2590
For a booking, the cancellation rate is the figure to plan around on DL 2590: 3.61% of its 332 scheduled flights did not operate. A late arrival costs roughly 50 minutes, but a cancellation costs the day, so leave a later option open.
