Historical statistics for July 2025 to June 2026, not live status. For today’s DL 407, check with Delta Air Lines.
DL 407 lands a B, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 295 flights, with a median arrival 6 minutes early.

These figures cover 295 flights between July 2025 and June 2026. The median arrival is 6 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 407 flies
DL 407 flies LAX to DTW without a single fixed slot. Its most common scheduled departure was 22:25, used on 102 of 295 flights, with 21:40 (31 flights) next. 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 22:25 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and DL 407 runs 10 points better at 80.8%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.
Against the route
DL 407 next to LAX to DTW

Across the year
DL 407 quarter by quarter
Quarter by quarter DL 407 held fairly steady: 77.2% in Jul–Sep 2025, 86.8% in Oct–Dec 2025 and 80.0% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Jan–Mar 202625 flights—

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, DL 407 did best on Wednesday at 88.4% on time and worst on Sunday at 70.5%. Each day rests on about 42 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Delay causes
Why DL 407 runs late
One category carries most of the weight here. Carrier accounts for 69% of the 4,244 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.
- 69%Carrier
- 23%Late-arriving aircraft
- 7%National Airspace System
The largest share of delay minutes, 69%, 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 2,944 of the 4,244 delay minutes reported here. The split is drawn from 4,244 delay minutes reported on DL 407.
Cancellations sit at 1.02% against a national 1.81%, 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 4.1% 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.
At 1,979 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The same number turns up on one other city pair in the data, including STT to BOS (61), but none flew often enough under DL 407 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to DTW only.
One caution: this is a thin sample. 295 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
