These figures cover 359 flights between September 2025 and August 2026. The median arrival is 11 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.

A 10:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and DL 2476 runs 3 points better at 86.9%. 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 2476 quarter by quarter

DL 2476 did not run the same all year. Its best quarter was Apr–Jun 2026 at 93.2% on time and its weakest Jul–Sep 2026 at 81.0%, a swing of 12 points on roughly 72 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.

Share of 350 completed flights by arrival against schedule.

9 of 34 late departures made up the time and arrived on time, 26% of them. In the other direction, 21 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 2476 runs late

National Airspace System accounts for 45% of the 3,056 delay minutes carriers reported here, and the remaining four split what is left.

National Airspace System
45%
Carrier
32%
Late-arriving aircraft
20%
Extreme weather
2%

45% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,376 minutes out of 3,056, against a national NAS share of 21%. The split is drawn from 3,056 delay minutes reported on DL 2476.

Cancellations run at 2.51%, against 1.89% nationally. That is about one flight in 40 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

Badly late arrivals are rare here: only 3.4% land an hour or more behind schedule, against 8.3% 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.

DL 2476 is not only a DTW to DCA flight. It also flew DCA to DTW (358 flights, 83.7% 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. 359 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 2476
