How DL754 performs
785 operations, June 2024 – July 2026.
DL754 arrived on time 88.4% of the time, against 84.8% for all SAN → DTW flights, so this departure is 3.6 percentage points better than the route as a whole. Against Delta Air Lines’ own flights on this route it is 3.3 points better.

What stands out
How DL754 compares to other flight numbers, not just to itself.
This flight stays close to typical even on its worst days, a smaller gap than 91% of 11,788 comparable flight numbers.
A typical arrival is 6 min early, and the worst tenth are only 22 minutes worse than that.

Why DL754 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
Share of the delay minutes US DOT attributed to each cause for DL754 on SAN → DTW. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies DL754 comes in late, and what that does to the departure.
DL754 is usually the aircraft’s first flight of the day: the schedule gives it a median of 7.7 hours on the ground at SAN, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, DL754 pushed back an average of 0 minutes late; when it came in on time or early, an average of 0 minutes early.
Each departure is matched to the flight the same aircraft flew into SAN just before it, using the tail number in the DOT file, 577 of 778 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 | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| DL754 | 26% | 5% | 4% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less on a turn this long than on a same-day one.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often DL754’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often DL754 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves SAN late, does that still matter by the time it reaches DTW?
DL754 pushes back an average of 2.7 minutes late and reaches the gate at DTW an average of 0.6 minutes early. The 3.3 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 27.1 minutes on the taxiways at SAN, 2.6 minutes longer than a typical SAN departure in the same hour.
On arrival at DTW, DL754 spends 9.8 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 DTW 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 DTW. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 26,464 departures from SAN scheduled in the clock hour DL754 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DTW (388,616 flights), not just DL754’s own. More on taxi time.

The hour it leaves SAN
Part of any flight’s record belongs to the clock rather than to the flight. DL754 has one departure time, so this is what that time is worth.
On-time arrival rate. 26,464 departures from SAN are scheduled in the 6 AM–7 AM hour over the period, against 297,668 across the whole day.
DL754 is scheduled out of SAN at 6:15 AM, in the 6 AM–7 AM bank. Departures from SAN in that hour arrive on time 92.2% of the time against 77.9% across the airport’s whole day — the slot alone is worth 14.2 points better before anything about this particular flight is considered.
The two airport figures cover every departure from SAN 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.

Because the same number has served different journeys, the statistics above describe only the route DL754 currently operates. Blending them would produce an average of two different flights.

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

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL754 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 785 records of DL754 operating SAN → DTW, 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.
