DL 2030 earns an F−, which is as low as this site's scale goes for a reason. Only 54.6% of flights arrive inside the 15-minute window, 23 points worse than the national rate of 77.3%. Late arrivals average about an hour. Treat any tight connection here as a coin flip. That rests on 306 flights, with a median arrival 11 minutes late.
The national on-time rate over the same period is 77.3%, so DL 2030 runs 23 points behind the country as a whole. Across a thousand flights that is about 227 extra late arrivals.

Across the year
DL 2030 quarter by quarter
DL 2030 did not run the same all year. Its best quarter was Oct–Dec 2025 at 62.7% on time and its weakest Jul–Sep 2026 at 44.2%, a swing of 19 points on roughly 77 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 202522 flights—
- Oct–Dec 202567 flights62.7%
- Jan–Mar 202677 flights46.6%
- Apr–Jun 202683 flights58.8%
- Jul–Sep 202657 flights44.2%
Scale runs 35% to 70%. Rows with fewer than 30 flights show a dash.
By weekday, DL 2030 did best on Wednesday at 64.6% on time and worst on Thursday at 45.8%. Each day rests on about 44 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Share of 293 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 81 departures that left 15 minutes late or more, only 4 made it up before arrival. In the other direction, 56 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.
The worst days
Worst days for DL 2030
The latest arrival of the period was on 19 May 2026, 16 hours 56 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across May, June, August, January and July, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 19 May 2026 | 16 hours 56 minutes | Extreme weather |
| 22 June 2026 | 4 hours 50 minutes | National Airspace System |
| 7 August 2026 | 3 hours 55 minutes | Extreme weather |

Delay causes
Why DL 2030 runs late
National Airspace System accounts for 55% of the 8,981 delay minutes carriers reported here, and the remaining four split what is left.
- 55%National Airspace System
- 25%Carrier
- 15%Extreme weather
- 5%Late-arriving aircraft
Extreme weather accounts for 15% 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 2.5 times the usual weather exposure. The split is drawn from 8,981 delay minutes reported on DL 2030.
Cancellations run at 3.27%, 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
15.0% 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.
DL 2030 is not only a DTW to DCA flight. It also flew DCA to DTW (279 flights, 66.9% 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. 306 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
