These figures cover 364 flights between September 2025 and August 2026. The median arrival is 14 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.

Schedule
When DL 410 flies
DL 410 is scheduled to leave Washington (DCA) at 06:00 local time and reach Atlanta (ATL) at 08:10. That slot held for 348 of the 364 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and DL 410 runs 5 points better at 94.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 July 2026 | 3 hours 11 minutes | Carrier |
| 7 July 2026 | 3 hours 8 minutes | Carrier |
| 16 March 2026 | 2 hours 14 minutes | National Airspace System |

Delay causes
Why DL 410 runs late
Carrier accounts for 73% of the 1,262 delay minutes carriers reported here, and the remaining four split what is left.
- 73%Carrier
- 27%National Airspace System
- 0%Extreme weather
The largest share of delay minutes, 73%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 917 of the 1,262 delay minutes reported here. The split is drawn from 1,262 delay minutes reported on DL 410.
Cancellations run at 3.02%, against 1.89% nationally. That is roughly 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
Badly late arrivals are rare here: only 2.0% 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.
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.
Every one of the 364 flights under DL 410 in the data flew DCA to ATL. The number was not reused on any other city pair, which makes this a clean record of one route.
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.
What to do with this
Booking DL 410
For a booking, the cancellation rate is the figure to plan around on DL 410: 3.02% of its 364 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
