Historical statistics for July 2025 to June 2026, not live status. For today’s DL 410, check with Delta Air Lines.

DL 410 earns an A−. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 17 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 55 minutes. That rests on 365 flights, with a median arrival 14 minutes early.

Set against the rest of the country, DL 410's record is 17 points better than the US average of 77.6%. That gap is worth roughly 173 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 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 07:44. That slot held for 349 of the 365 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

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 6 points better at 94.9%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

DL 410 next to DCA to ATL

Every carrier on DCA to ATL combined arrived on time 78.8% of the time across 6,813 flights, so DL 410 is 16 points ahead of it. Delta flew 3,838 flights on the same city pair under all its flight numbers, including this one, and those ran 80.9% on time. Across its whole network Delta Air Lines managed 81.6%, which this flight beats by 13 points.

Across the year

DL 410 quarter by quarter

Quarter by quarter DL 410 held fairly steady: 94.4% in Jul–Sep 2025, 96.6% in Oct–Dec 2025, 92.9% in Jan–Mar 2026 and 95.6% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights94.4%
Oct–Dec 202592 flights96.6%
Jan–Mar 202690 flights92.9%
Apr–Jun 202691 flights95.6%

Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, DL 410 did best on Wednesday at 100.0% on time and worst on Monday at 87.0%. Each day rests on about 52 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 410 runs late

One category carries most of the weight here. National Airspace System accounts for 50% of the 981 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.

50% 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 493 minutes out of 981, against a national NAS share of 21%. The split is drawn from 981 delay minutes reported on DL 410.

Cancellations run at 3.56%, 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

Badly late arrivals are rare here: only 1.4% land an hour or more behind schedule, against 8.1% 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 365 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. 365 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: 3.56% of its 365 scheduled flights did not operate. A late arrival costs about 55 minutes, but a cancellation costs the day, so leave a later option open.
