Why AA2904 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 AA2904 on SFO → DFW. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies AA2904 comes in late, and what that does to the departure.
AA2904 is usually the aircraft’s first flight of the day: the schedule gives it a median of 10.3 hours on the ground at SFO, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, AA2904 pushed back an average of 15 minutes late; when it came in on time or early, an average of 22 minutes late.
Each departure is matched to the flight the same aircraft flew into SFO just before it, using the tail number in the DOT file, 518 of 1,091 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 |
|---|---|---|---|
| AA2904 | 47% | 15% | 11% |
| 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 AA2904’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AA2904 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves SFO late, does that still matter by the time it reaches DFW?
AA2904 pushes back an average of 34.1 minutes late and reaches the gate at DFW an average of 24.9 minutes late. The 9.2 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 16.0 minutes on the taxiways at SFO, 7.0 minutes shorter than a typical SFO departure in the same hour.
On arrival at DFW, AA2904 spends 11.8 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 1.7 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 38,724 departures from SFO scheduled in the clock hour AA2904 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 AA2904’s own. More on taxi time.

The hour it leaves SFO
Part of any flight’s record belongs to the clock rather than to the flight. AA2904 has one departure time, so this is what that time is worth.
On-time arrival rate. 38,724 departures from SFO are scheduled in the 8 AM–9 AM hour over the period, against 435,779 across the whole day.
AA2904 is scheduled out of SFO at 8:00 AM, in the 8 AM–9 AM bank. Departures from SFO in that hour arrive on time 85.2% of the time against 78.7% across the airport’s whole day — the slot alone is worth 6.5 points better before anything about this particular flight is considered.
The two airport figures cover every departure from SFO 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 AA2904 run worse on particular days?
Wednesday is historically the most reliable day and Thursday the least, a gap of 8.2 percentage points.

Other routes AA2904 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 |
|---|---|---|---|
| DFW→MSY Dallas–Fort Worth to New Orleans | May 6, 2024 – December 18, 2024 | 192 | 60.0% |
| MCI→ORD Kansas City to Chicago | December 5, 2023 | 1 | — |
Because the same number has served different journeys, the statistics above describe only the route AA2904 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 |
|---|---|---|---|---|

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. AA2904 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 1,109 records of AA2904 operating SFO → 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.
