Why AA1404 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
screening or terminal security incidents
Share of the delay minutes US DOT attributed to each cause for AA1404 on DEN → PHX. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies AA1404 comes in late, and what that does to the departure.
AA1404 is usually the aircraft’s first flight of the day: the schedule gives it a median of 9.4 hours on the ground at DEN, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, AA1404 pushed back an average of 15 minutes late; when it came in on time or early, an average of 15 minutes late.
Each departure is matched to the flight the same aircraft flew into DEN just before it, using the tail number in the DOT file, 931 of 1,082 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 |
|---|---|---|---|
| AA1404 | 31% | 17% | 13% |
| 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 AA1404’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often AA1404 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves DEN late, does that still matter by the time it reaches PHX?
On arrival at PHX, AA1404 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 2.3 minutes longer than a typical PHX arrival (7.5 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 PHX. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 53,796 departures from DEN scheduled in the clock hour AA1404 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at PHX (598,496 flights), not just AA1404’s own. More on taxi time.

The hour it leaves DEN
Part of any flight’s record belongs to the clock rather than to the flight. AA1404 has one departure time, so this is what that time is worth.
On-time arrival rate. 53,796 departures from DEN are scheduled in the 8 AM–9 AM hour over the period, against 963,099 across the whole day.
AA1404 is scheduled out of DEN at 8:00 AM, in the 8 AM–9 AM bank. Departures from DEN in that hour arrive on time 86.8% of the time against 76.0% across the airport’s whole day — the slot alone is worth 10.8 points better before anything about this particular flight is considered.
The two airport figures cover every departure from DEN 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 AA1404 run worse on particular days?
Saturday is historically the most reliable day and Tuesday the least, a gap of 10.6 percentage points.

Other routes AA1404 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 |
|---|---|---|---|
| IND→DFW Indianapolis to Dallas–Fort Worth | May 13, 2026 | 1 | — |
Because the same number has served different journeys, the statistics above describe only the route AA1404 currently operates. Blending them would produce an average of two different flights.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. AA1404 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 1,095 records of AA1404 operating DEN → PHX, 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.
