Historical statistics for July 2025 to June 2026, not live status. For today’s DL 2030, check with Delta Air Lines.
DL 2030 draws a D−. Roughly one flight in two arrives at least 15 minutes late, and the typical late arrival is about an hour behind schedule. Build slack into anything you connect to. That rests on 301 flights, with a median arrival 9 minutes late.
The national on-time rate over the same period is 77.6%, so DL 2030 runs 20 points behind the country as a whole. Across a thousand flights that is about 196 extra late arrivals.

These figures cover 301 flights between July 2025 and June 2026. Beyond the headline rate, 13.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When DL 2030 flies
DL 2030 flies DTW to DCA without a single fixed slot. Its most common scheduled departure was 17:27, used on 77 of 301 flights, with 17:26 (57 flights) and 17:30 (57 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

- Departs 17:2657 flights18.9%
- Departs 17:3057 flights18.9%

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 17:27 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and DL 2030 runs 10 points worse at 58.0%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.
Against the route
DL 2030 next to DTW to DCA

Delta flew 1,745 flights on the same city pair under all its flight numbers, including this one, and those ran 68.8% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight trails by 24 points.

Across the year
DL 2030 quarter by quarter
DL 2030 did not run the same all year. Its best quarter was Jul–Sep 2025 at 64.7% on time and its weakest Jan–Mar 2026 at 46.6%, a swing of 18 points on roughly 75 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.
- Jul–Sep 202574 flights64.7%
- Oct–Dec 202567 flights62.7%
- Jan–Mar 202677 flights46.6%
- Apr–Jun 202683 flights58.8%
Scale runs 40% to 70%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2030 did best on Tuesday at 63.3% on time and worst on Thursday at 46.9%. Each day rests on about 43 flights, so a gap of 16 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 2030 runs late
One category carries most of the weight here. National Airspace System accounts for 58% of the 8,221 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.
- 58%National Airspace System
- 24%Carrier
- 13%Extreme weather
- 5%Late-arriving aircraft
Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.1 times the usual weather exposure. The split is drawn from 8,221 delay minutes reported on DL 2030.
Cancellations run at 3.32%, against 1.81% 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 13.5% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
DL 2030 is not only a DTW to DCA flight. It also flew DCA to DTW (299 flights, 69.8% 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. 301 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 2030
For a booking, the cancellation rate is the figure to plan around on DL 2030: 3.32% of its 301 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
