These figures cover 364 flights between September 2025 and August 2026. The median arrival is 7 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 12:20 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.3%, and DL 380 runs level with that at 77.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 380 quarter by quarter
DL 380 did not run the same all year. Its best quarter was Jul–Sep 2025 at 90.0% on time and its weakest Jul–Sep 2026 at 64.4%, a swing of 26 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.

Scale runs 55% to 95%.
By weekday, DL 380 did best on Thursday at 86.5% on time and worst on Sunday at 66.7%. Each day rests on about 52 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

The worst days
Worst days for DL 380
The latest arrival of the period was on 26 January 2026, 7 hours behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 26 January 2026 | 7 hours | Late-arriving aircraft |
| 3 July 2026 | 6 hours 47 minutes | National Airspace System |
| 28 March 2026 | 6 hours 14 minutes | Carrier |
| 15 August 2026 | 5 hours 20 minutes | Carrier |
| 19 July 2026 | 4 hours 47 minutes | Carrier |
Delay causes
Why DL 380 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 6,019 reported delay minutes.
- 40%Late-arriving aircraft
- 35%Carrier
- 24%National Airspace System
- 1%Extreme weather
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,019 reported delay minutes here, that single category outweighs weather by 40 to one. The split is drawn from 6,019 delay minutes reported on DL 380.
Cancellations are rare at 0.55%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
7.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
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 380 is not only a DCA to ATL flight. It also flew ATL to DCA (363 flights, 80.4% 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. 364 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.
