Historical statistics for July 2025 to June 2026, not live status. For today’s DL 708, check with Delta Air Lines.

DL 708 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 roughly 55 minutes on average. That is a workable record, not a spotless one. That rests on 300 flights, with a median arrival 9 minutes early.

These figures cover 300 flights between July 2025 and June 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.

Schedule

When DL 708 flies

DL 708 flies LAX to DTW without a single fixed slot. Its most common scheduled departure was 15:12, used on 56 of 300 flights, with 15:50 (49 flights) and 15:36 (41 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 15:12 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and DL 708 runs 8 points better at 80.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Against the route

DL 708 next to LAX to DTW

Every carrier on LAX to DTW combined arrived on time 82.7% of the time across 2,528 flights, so DL 708 is 2 points behind it. Delta flew 1,979 flights on the same city pair under all its flight numbers, including this one, and those ran 83.6% on time. Across its whole network Delta Air Lines managed 81.6%, close to this flight's figure.

Across the year

DL 708 quarter by quarter

Quarter by quarter DL 708 held fairly steady: 83.5% in Jul–Sep 2025, 83.1% in Oct–Dec 2025 and 78.7% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jan–Mar 202628 flights—

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, DL 708 did best on Wednesday at 90.7% on time and worst on Thursday at 66.7%. Each day rests on about 43 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why DL 708 runs late

One category carries most of the weight here. Carrier accounts for 49% of the 3,120 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
49%
Late-arriving aircraft
33%
National Airspace System
18%

The largest share of delay minutes, 49%, 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 1,525 of the 3,120 delay minutes reported here. The split is drawn from 3,120 delay minutes reported on DL 708.

Cancellations sit at 1.00% against a national 1.81%, which is ordinary. Diversions add another 0.33%.

Connections and routes

What a delay on this flight costs

6.1% 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 roughly 55 minutes, which a normal layover absorbs.

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 two other city pairs in the data, including PBI to BOS (62) and BOS to PBI (4), but none flew often enough under DL 708 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. 300 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 708

For a booking, read DL 708 as 80.4% on time with 1.00% cancelled over 300 flights. Those are rates from the past twelve months, not a forecast for any particular day.
