Historical statistics for July 2025 to June 2026, not live status. For today’s DL 1407, check with Delta Air Lines.

DL 1407 earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 365 flights, with a median arrival 8 minutes early.

Set against the rest of the country, DL 1407's record is 7 points better than the US average of 77.6%. That gap is worth roughly 71 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 8 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 1407 flies

DL 1407 flies DTW to RDU without a single fixed slot. Its most common scheduled departure was 15:55, used on 81 of 365 flights. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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

A 15:55 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 1407 runs 12 points better at 84.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

DL 1407 next to DTW to RDU

Across the year

DL 1407 quarter by quarter

Quarter by quarter DL 1407 held fairly steady: 86.8% in Jul–Sep 2025, 82.4% in Oct–Dec 2025, 83.0% in Jan–Mar 2026 and 86.5% 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 flights86.8%
Oct–Dec 202592 flights82.4%
Jan–Mar 202690 flights83.0%
Apr–Jun 202691 flights86.5%

Scale runs 75% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 1407 ranged from 79.6% on Sunday to 90.4% on Tuesday. With about 52 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why DL 1407 runs late

One category carries most of the weight here. Carrier accounts for 56% of the 3,035 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.

Carrier
56%
Late-arriving aircraft
19%
National Airspace System
17%
Extreme weather
7%

The largest share of delay minutes, 56%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,714 of the 3,035 delay minutes reported here. The split is drawn from 3,035 delay minutes reported on DL 1407.

Cancellations sit at 1.37% against a national 1.81%, which is ordinary. Diversions add another 0.27%.

Connections and routes

What a delay on this flight costs

5.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

The 501 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.

The same number turns up on one other city pair in the data, including RDU to DTW (179), but none flew often enough under DL 1407 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DTW to RDU only.

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 1407

For a booking, read DL 1407 as 84.7% on time with 1.37% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
