DL 708 lands a B+, 5 points better than the national rate of 77.3%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 300 flights, with a median arrival 9 minutes early.
Set against the rest of the country, DL 708's record is 5 points better than the US average of 77.3%. That gap is worth roughly 45 fewer late arrivals for every thousand flights.

These figures cover 300 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 708 quarter by quarter
DL 708 did not run the same all year. Its best quarter was Jul–Sep 2026 at 88.7% on time and its weakest Apr–Jun 2026 at 78.7%, a swing of 10 points on roughly 75 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.
- Jul–Sep 202530 flights86.7%
- Oct–Dec 202589 flights83.1%
- Jan–Mar 202628 flights—
- Apr–Jun 202691 flights78.7%
- Jul–Sep 202662 flights88.7%
Scale runs 70% to 95%. 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.

The worst days
Worst days for DL 708
The latest arrival of the period was on 5 August 2026, 4 hours 24 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 5 August 2026 | 4 hours 24 minutes | Late-arriving aircraft |
| 21 November 2025 | 2 hours 57 minutes | Carrier |
| 30 October 2025 | 2 hours 46 minutes | Carrier |
| 6 October 2025 | 2 hours 22 minutes | Carrier |
| 18 May 2026 | 2 hours 22 minutes | Late-arriving aircraft |
Delay causes
Why DL 708 runs late
Carrier accounts for 45% of the 3,173 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 41%Late-arriving aircraft
- 14%National Airspace System
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,173 reported delay minutes here, that single category outweighs weather by 41 to one. The split is drawn from 3,173 delay minutes reported on DL 708.
Cancellations are rare at 0.67%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
5.7% of arrivals land an hour or more late, close to the national 8.3%, so 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.
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
