These figures cover 365 flights between September 2025 and August 2026. The median arrival is 9 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.

Across the year
DL 1407 quarter by quarter
DL 1407 did not run the same all year. Its best quarter was Jul–Sep 2025 at 86.7% on time and its weakest Jul–Sep 2026 at 75.8%, a swing of 11 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.

- Oct–Dec 202592 flights82.4%
- Jan–Mar 202690 flights83.0%

Scale runs 65% to 90%.
By weekday, DL 1407 did best on Saturday at 90.2% on time and worst on Monday at 77.4%. Each day rests on about 52 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Share of 360 completed flights by arrival against schedule.
A late pushback is often recovered here: of 64 departures that left 15 minutes late or more, 20 still arrived on time. In the other direction, 18 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 RDU.

Delay causes
Why DL 1407 runs late

- 50%Carrier
- 26%National Airspace System
- 22%Late-arriving aircraft
- 1%Extreme weather
The largest share of delay minutes, 50%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,374 of the 2,722 delay minutes reported here. The split is drawn from 2,722 delay minutes reported on DL 1407.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.6% 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 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.
The same number turns up on one other city pair in the data, including RDU to DTW (200), 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 82.8% on time with 1.37% cancelled over 365 flights. Those are rates from the past twelve months, not a forecast for any particular day.
