How DL1185 performs
785 operations, June 2024 – July 2026.
DL1185 arrived on time 90.9% of the time, against 86.6% for all SNA → SLC flights, so this departure is 4.3 percentage points better than the route as a whole. Against Delta Air Lines’ own flights on this route it is 4.3 points better.

What stands out
How DL1185 compares to other flight numbers, not just to itself.
This flight stays close to typical even on its worst days, a smaller gap than 90% of 11,788 comparable flight numbers.
A typical arrival is 10 min early, and the worst tenth are only 23 minutes worse than that.

Why DL1185 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 DL1185 on SNA → SLC. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies DL1185 comes in late, and what that does to the departure.
DL1185 is usually the aircraft’s first flight of the day: the schedule gives it a median of 9.1 hours on the ground at SNA, so its “inbound” is mostly the aircraft’s arrival the evening before.
The aircraft flying DL1185 came in 15 or more minutes late on 16% 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 SNA just before it, using the tail number in the DOT file, 748 of 784 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 |
|---|---|
| DL1185 | 16% |
| Network, same turn | 29% |
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 DL1185’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 SNA late, does that still matter by the time it reaches SLC?
DL1185 pushes back an average of 8.3 minutes late and reaches the gate at SLC an average of 2.0 minutes late. The 6.3 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 20.2 minutes on the taxiways at SNA, 1.3 minutes longer than a typical SNA departure in the same hour.
On arrival at SLC, DL1185 spends 8.3 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 1.2 minutes longer than a typical SLC arrival (7.1 min).
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 SLC. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 12,251 departures from SNA scheduled in the clock hour DL1185 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at SLC (355,118 flights), not just DL1185’s own. More on taxi time.

The hour it leaves SNA
Part of any flight’s record belongs to the clock rather than to the flight. DL1185 has one departure time, so this is what that time is worth.
On-time arrival rate. 12,251 departures from SNA are scheduled in the 7 AM–8 AM hour over the period, against 137,357 across the whole day.
DL1185 is scheduled out of SNA at 7:00 AM, in the 7 AM–8 AM bank. Departures from SNA in that hour arrive on time 90.4% of the time against 82.2% across the airport’s whole day — the slot alone is worth 8.2 points better before anything about this particular flight is considered.
The two airport figures cover every departure from SNA 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.

Other routes DL1185 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 |
|---|---|---|---|
| MSP→BOS Minneapolis to Boston | September 5, 2023 – June 6, 2024 | 156 | 81.4% |
| ATL→PHL Atlanta to Philadelphia | March 10, 2024 – May 6, 2024 | 58 | — |
| ATL→CHS Atlanta to Charleston | January 8, 2024 – March 6, 2024 | 29 | — |
| DTW→JFK Detroit to New York | July 2, 2023 – September 4, 2023 | 62 | — |
| MSP→JAC Minneapolis to Jackson | July 1–8, 2023 | 2 | — |
Because the same number has served different journeys, the statistics above describe only the route DL1185 currently operates. Blending them would produce an average of two different flights.

Other flights on this route
Same airports, same journey, different odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| DL1185 this flight | Delta Air Lines | 90.9% | 10 min early | 785 |

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL1185 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 DL1185 operating SNA → SLC, 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.
