Why AA1678 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding, fueling — 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
Share of the delay minutes US DOT attributed to each cause for AA1678 on CLT → PHX. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.

From pushback to gate
When it leaves CLT late, does that still matter by the time it reaches PHX?
AA1678 pushes back an average of 6.1 minutes late and reaches the gate at PHX an average of 3.7 minutes late. The 2.4 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. It spends 18.2 minutes on the taxiways at CLT, 2.1 minutes shorter than a typical CLT departure in the same hour.
On arrival at PHX, AA1678 spends 11.1 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 3.7 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 43,098 departures from CLT scheduled in the clock hour AA1678 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 AA1678’s own. More on taxi time.

The hour it leaves CLT
Part of any flight’s record belongs to the clock rather than to the flight. AA1678 has one departure time, so this is what that time is worth.
On-time arrival rate. 43,098 departures from CLT are scheduled in the 7 AM–8 AM hour over the period, against 618,243 across the whole day.
AA1678 is scheduled out of CLT at 7:30 AM, in the 7 AM–8 AM bank. Departures from CLT in that hour arrive on time 86.6% of the time against 74.8% across the airport’s whole day — the slot alone is worth 11.8 points better before anything about this particular flight is considered.
The two airport figures cover every departure from CLT 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 AA1678 run worse on particular days?
Tuesday is historically the most reliable day and Friday the least, a gap of 7.5 percentage points.

Other routes AA1678 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.
Because the same number has served different journeys, the statistics above describe only the route AA1678 currently operates. Blending them would produce an average of two different flights.
When it goes wrong

Data and methodology
Calculated by FlyerIntel from 966 records of AA1678 operating CLT → 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.
