How DL908 performs
921 operations, July 2023 – July 2026.
DL908 arrived on time 78.9% of the time, against 81.0% for all DTW → LAX flights, so this departure is 2.1 percentage points worse than the route as a whole. Against Delta Air Lines’ own flights on this route it is 1.4 points worse.

Why DL908 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for DL908 on DTW → LAX. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies DL908 comes in late, and what that does to the departure.
The aircraft flying DL908 came in 15 or more minutes late on 11% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Each departure is matched to the flight the same aircraft flew into DTW just before it, using the tail number in the DOT file, 889 of 917 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late |
|---|---|
| DL908 | 11% |
| Network, same turn | 17% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often DL908’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves DTW late, does that still matter by the time it reaches LAX?
DL908 pushes back an average of 14.4 minutes late and reaches the gate at LAX an average of 3.8 minutes late. The 10.6 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 16.3 minutes on the taxiways at DTW, 1.7 minutes shorter than a typical DTW departure in the same hour.
On arrival at LAX, DL908 spends 10.1 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is about what any arrival at LAX spends on the ground before reaching the gate.
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached LAX. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 35,020 departures from DTW scheduled in the clock hour DL908 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at LAX (595,170 flights), not just DL908’s own. More on taxi time.

The hour it leaves DTW
Part of any flight’s record belongs to the clock rather than to the flight. DL908 has one departure time, so this is what that time is worth.
On-time arrival rate. 35,020 departures from DTW are scheduled in the 4 PM–5 PM hour over the period, against 388,632 across the whole day.
DL908 is scheduled out of DTW at 4:25 PM, in the 4 PM–5 PM bank. Departures from DTW in that hour arrive on time 76.0% of the time against 79.6% across the airport’s whole day — the slot alone is worth 3.6 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from DTW to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

By day of week
Does DL908 run worse on particular days?
Wednesday is historically the most reliable day and Sunday the least, a gap of 15.9 percentage points.

Other routes DL908 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| RSW→JFK Fort Myers to New York | August 11, 2025 – December 19, 2025 | 131 | 85.8% |
| SLC→ATL Salt Lake City to Atlanta | January 8, 2024 – March 9, 2024 | 62 | — |
Because the same number has served different journeys, the statistics above describe only the route DL908 currently operates. Blending them would produce an average of two different flights.

Same airports, same journey, different odds of arriving on time.

|---|---|---|---|---|
| DL794 | Delta Air Lines | 86.9% | 9 min early | 815 |

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL908 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 921 records of DL908 operating DTW → LAX, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
