Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| AA1412 | 89.4% | 1.15% | -11 min | 5.2% | 1,127 |
| American Airlines on ONT → DFW | 81.2% | 2.10% | -9 min | 7.7% | 6,107 |
| All ONT → DFW flights | 80.0% | 2.17% | -8 min | 7.9% | 7,290 |
AA1412 has cancelled 1.15% of its scheduled departures (13 of 1,127), against 2.17% for all ONT → DFW flights — this specific departure cancels 1.0 percentage points less often than the route as a whole. Different flight numbers on the same route can carry different aircraft, crews and schedules, so this is a fact about AA1412 specifically, not about the route it flies.

Why AA1412 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
weather severe enough to stop this flight specifically
airspace and airport capacity, including weather-driven flow control
Share of the delay minutes US DOT attributed to each cause for AA1412 on ONT → DFW. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies AA1412 comes in late, and what that does to the departure.
AA1412 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8.6 hours on the ground at ONT, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, AA1412 pushed back an average of 12 minutes late; when it came in on time or early, an average of 10 minutes late.
Each departure is matched to the flight the same aircraft flew into ONT just before it, using the tail number in the DOT file, 977 of 1,114 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 |
|---|---|---|---|
| AA1412 | 43% | 11% | 8% |
| 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 AA1412’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AA1412 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves ONT late, does that still matter by the time it reaches DFW?
AA1412 pushes back an average of 11.3 minutes late and reaches the gate at DFW an average of 4.9 minutes late. The 6.4 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. Its 14.6 minutes on the taxiways at ONT is about what any departure from the airport in that hour spends.
On arrival at DFW, AA1412 spends 12.6 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 1.0 minutes shorter than a typical DFW arrival (13.5 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 DFW. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 11,078 departures from ONT scheduled in the clock hour AA1412 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DFW (961,642 flights), not just AA1412’s own. More on taxi time.

The hour it leaves ONT
Part of any flight’s record belongs to the clock rather than to the flight. AA1412 has one departure time, so this is what that time is worth.
On-time arrival rate. 11,078 departures from ONT are scheduled in the 6 AM–7 AM hour over the period, against 79,949 across the whole day.
AA1412 is scheduled out of ONT at 6:00 AM, in the 6 AM–7 AM bank. Departures from ONT in that hour arrive on time 92.6% of the time against 83.5% across the airport’s whole day — the slot alone is worth 9.1 points better before anything about this particular flight is considered.
The two airport figures cover every departure from ONT 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.

Does AA1412 run worse on particular days?
Thursday is historically the most reliable day and Friday the least, a gap of 6.9 percentage points.

Other flights on this route
Same airports, same journey, different odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| AA1412 this flight | American Airlines | 89.4% | 11 min early | 1,127 |

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. AA1412 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 1,127 records of AA1412 operating ONT → DFW, 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.
