Why AA529 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 AA529 comes in late, and what that does to the departure.
The aircraft flying AA529 came in 15 or more minutes late on 19% 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 ORD: 549 of 605 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 |
|---|---|
| AA529 | 19% |
| Network, same turn | 17% |
63 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 AA529’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 ORD late, does that still matter by the time it reaches LAX?
AA529 pushes back an average of 25.1 minutes late and reaches the gate at LAX an average of 15.8 minutes late. The 9.3 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 20.1 minutes on the taxiways at ORD, 4.2 minutes shorter than a typical ORD departure in the same hour.
On arrival at LAX, AA529 spends 7.6 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 3.2 minutes shorter than a typical LAX arrival (10.8 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 51,725 ORD departures. Taxi-in is landing to gate, set against 611,660 arrivals at LAX. More on taxi time.

The hour it leaves ORD
AA529 has one departure time, 3:00 PM, so this is what that hour at ORD is worth.
On-time arrival rate. 51,725 departures from ORD are scheduled in the 3 PM–4 PM hour over the period, against 985,989 across the whole day.
AA529 is scheduled out of ORD at 3:00 PM, in the 3 PM–4 PM bank. Departures from ORD in that hour arrive on time 70.8% of the time against 74.2% across the airport’s whole day — the slot alone is worth 3.3 points worse before anything about this particular flight is considered.
Both airport figures cover every destination from ORD, 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.
79 min late
against a median of 5 min early
AA529 has an average that understates its risk: a typical arrival is 5 min early, but the worst tenth are 84 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.
