DL 1592 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 291 flights, with a median arrival 14 minutes early.
Set against the rest of the country, DL 1592's record is 12 points better than the US average of 77.6%. That gap is worth roughly 115 fewer late arrivals for every thousand flights.

These figures cover 291 flights between July 2025 and June 2026. The median arrival is 14 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 1592 flies
DL 1592 flies BWI to ATL without a single fixed slot. Its most common scheduled departure was 10:28, used on 71 of 291 flights, with 10:18 (44 flights) and 10:33 (38 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 10:28 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and DL 1592 runs 5 points better at 89.1%. 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 1592 quarter by quarter
DL 1592 did not run the same all year. Its best quarter was Jul–Sep 2025 at 97.4% on time and its weakest Oct–Dec 2025 at 79.7%, a swing of 18 points on roughly 73 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 202576 flights79.7%
- Jan–Mar 202661 flights87.7%

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, DL 1592 ranged from 83.7% on Sunday to 93.8% on Friday. With about 42 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why DL 1592 runs late
One category carries most of the weight here. Carrier accounts for 57% of the 2,497 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 57%Carrier
- 29%Late-arriving aircraft
- 12%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 57%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,422 of the 2,497 delay minutes reported here. The split is drawn from 2,497 delay minutes reported on DL 1592.
Cancellations sit at 2.06% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.5% land an hour or more behind schedule, against 8.1% 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 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
DL 1592 is not only a BWI to ATL flight. It also flew ATL to BWI (254 flights, 89.2% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 291 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.
