DL 832 earns a D−, which is as low as this site's scale goes for a reason. Only 55.1% of flights arrive inside the 15-minute window, 22 points worse than the national rate of 77.3%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 328 flights, with a median arrival 10 minutes late.

The national on-time rate over the same period is 77.3%, so DL 832 runs 22 points behind the country as a whole. Across a thousand flights that is about 222 extra late arrivals.

Across the year

DL 832 quarter by quarter

DL 832 did not run the same all year. Its best quarter was Apr–Jun 2026 at 64.0% on time and its weakest Jul–Sep 2026 at 31.7%, a swing of 32 points on roughly 82 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 832 did best on Wednesday at 69.4% on time and worst on Thursday at 46.9%. Each day rests on about 47 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Arrival by arrival

The 142 late arrivals split 35 under half an hour, 51 between 30 and 60 minutes, and 56 an hour or more.

Share of 316 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 120 departures that left 15 minutes late or more, only 8 made it up before arrival. In the other direction, 30 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 DCA.

Delay causes

Why DL 832 runs late

National Airspace System accounts for 50% of the 9,817 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
35%
Late-arriving aircraft
14%
Extreme weather

The largest share of delay minutes, 35%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 3,409 of the 9,817 delay minutes reported here. The split is drawn from 9,817 delay minutes reported on DL 832.

Cancellations run at 3.35%, 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

17.7% 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 547 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.

DL 832 is not only a ATL to DCA flight. It also flew DCA to ATL (256 flights, 71.6% 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. 328 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 832

For a booking, the cancellation rate is the figure to plan around on DL 832: 3.35% of its 328 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.
