Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| AA2012 | 76.6% | 2.25% | -5 min | 9.9% | 621 |
| American Airlines on ORD → LAX | 73.3% | 1.22% | -5 min | 9.8% | 9,338 |
| All ORD → LAX flights | 75.9% | 1.18% | -5 min | 8.9% | 21,935 |
AA2012 has cancelled 2.25% of its scheduled departures (14 of 621), against 1.18% for all ORD → LAX flights — this specific departure cancels 1.1 percentage points more often than the route as a whole. Different flight numbers on the same route can carry different aircraft, crews and schedules, so this is a fact about AA2012 specifically, not about the route it flies.

Why AA2012 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
Share of the delay minutes US DOT attributed to each cause for AA2012 on ORD → LAX. Only delays of 15 minutes or more are attributed. What the five causes mean

Does a late aircraft delay this flight?
How often the plane that flies AA2012 comes in late, and what that does to the departure.
The aircraft flying AA2012 came in 15 or more minutes late on 21% 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: 399 of 607 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 |
|---|---|
| AA2012 | 21% |
| Network, same turn | 23% |
A long gap on the ground gives a late aircraft room to catch up before this flight pushes back.
The network row is every flight with a scheduled turn of 90 minutes to 3 hours. How often AA2012’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?
AA2012 pushes back an average of 22.4 minutes late and reaches the gate at LAX an average of 14.3 minutes late. The 8.1 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 21.5 minutes on the taxiways at ORD, 4.0 minutes shorter than a typical ORD departure in the same hour.
On arrival at LAX, AA2012 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 1.0 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 86,301 ORD departures. Taxi-in is landing to gate, set against 611,660 arrivals at LAX. More on taxi time.

The hour it leaves ORD
AA2012 has one departure time, 8:15 AM, so this is what that hour at ORD is worth.
On-time arrival rate. 86,301 departures from ORD are scheduled in the 8 AM–9 AM hour over the period, against 985,989 across the whole day.
AA2012 is scheduled out of ORD at 8:15 AM, in the 8 AM–9 AM bank. Departures from ORD in that hour arrive on time 81.2% of the time against 74.2% across the airport’s whole day — the slot alone is worth 7.0 points better 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.
56 min late
against a median of 5 min early
AA2012 has an average that understates its risk: a typical arrival is 5 min early, but the worst tenth are 61 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 621 records of AA2012 operating ORD → LAX, 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.
