Why AA1403 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
weather severe enough to stop this flight specifically
screening or terminal security incidents

Does a late aircraft delay this flight?
How often the plane that flies AA1403 comes in late, and what that does to the departure.
AA1403 is usually the aircraft’s first flight of the day: the schedule gives it a median of 7.1 hours on the ground at BWI, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, AA1403 pushed back an average of 19 minutes late; when it came in on time or early, an average of 5 minutes late.
Each departure is matched to the flight the same aircraft flew into BWI just before it, using the tail number in the DOT file, 1,056 of 1,093 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 |
|---|---|---|---|
| AA1403 | 37% | 10% | 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 AA1403’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AA1403 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves BWI late, does that still matter by the time it reaches DFW?
AA1403 pushes back an average of 11.4 minutes late and reaches the gate at DFW an average of 1.3 minutes late. The 10.0 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 16.8 minutes on the taxiways at BWI is about what any departure from the airport in that hour spends.
On arrival at DFW, AA1403 spends 15.8 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 2.3 minutes longer 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 28,419 departures from BWI scheduled in the clock hour AA1403 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 AA1403’s own. More on taxi time.

The hour it leaves BWI
Part of any flight’s record belongs to the clock rather than to the flight. AA1403 has one departure time, so this is what that time is worth.
On-time arrival rate. 28,419 departures from BWI are scheduled in the 6 AM–7 AM hour over the period, against 299,178 across the whole day.
AA1403 is scheduled out of BWI at 6:03 AM, in the 6 AM–7 AM bank. Departures from BWI in that hour arrive on time 90.2% of the time against 76.0% across the airport’s whole day — the slot alone is worth 14.3 points better before anything about this particular flight is considered.
The two airport figures cover every departure from BWI 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.

Tuesday is historically the most reliable day and Friday the least, a gap of 10.1 percentage points.

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. AA1403 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 1,126 records of AA1403 operating BWI → 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.
