Why AA1456 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
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 AA1456 comes in late, and what that does to the departure.
The aircraft flying AA1456 came in 15 or more minutes late on 15% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Matched by tail number to the aircraft’s previous flight into DFW: 744 of 867 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late |
|---|---|
| AA1456 | 15% |
| Network, same turn | 17% |
61 scheduled minutes is enough to clean and board when the aircraft is on time, with little to spare when it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often AA1456’s aircraft landed 15 or more minutes late is about the same as the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves DFW late, does that still matter by the time it reaches SLC?
AA1456 pushes back an average of 26.0 minutes late and reaches the gate at SLC an average of 20.0 minutes late. The 6.0 minutes between those two figures are slack the published schedule already carries, so a late pushback is partly, not fully, made up before the gate. It spends 15.5 minutes on the taxiways at DFW, 1.9 minutes shorter than a typical DFW departure in the same hour.
On arrival at SLC, AA1456 spends 7.0 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 about what any arrival at SLC spends on the ground before reaching the gate.
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 44,170 DFW departures. Taxi-in is landing to gate, set against 365,173 arrivals at SLC. More on taxi time.

The hour it leaves DFW
AA1456 has one departure time, 1:30 PM, so this is what that hour at DFW is worth.
On-time arrival rate. 44,170 departures from DFW are scheduled in the 1 PM–2 PM hour over the period, against 989,065 across the whole day.
AA1456 is scheduled out of DFW at 1:30 PM, in the 1 PM–2 PM bank. Departures from DFW in that hour arrive on time 71.4% of the time against 73.1% across the airport’s whole day, so the hour AA1456 leaves in is an ordinary one for DFW and explains nothing about its record either way.
Both airport figures cover every destination from DFW, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
71 min late
against a median of 2 min late
AA1456 has an average that understates its risk: a typical arrival is 2 min late, but the worst tenth are 69 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Data and methodology
Calculated by FlyerIntel from 887 records of AA1456 operating DFW → SLC, 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 reported separately, not in the on-time rate.
