Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| AA1584 | 81.7% | 3.27% | -7 min | 7.1% | 703 |
| American Airlines on LAS → DFW | 78.6% | 2.42% | -9 min | 8.9% | 12,438 |
| All LAS → DFW flights | 78.1% | 2.10% | -8 min | 8.7% | 17,679 |
AA1584 has cancelled 3.27% of its scheduled departures (23 of 703), against 2.10% for all LAS → DFW flights — this specific departure cancels 1.2 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 AA1584 specifically, not about the route it flies.

Why AA1584 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 AA1584 on LAS → DFW. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies AA1584 comes in late, and what that does to the departure.
The aircraft flying AA1584 came in 15 or more minutes late on 18% 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.
Each departure is matched to the flight the same aircraft flew into LAS just before it, using the tail number in the DOT file, 643 of 681 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 |
|---|---|
| AA1584 | 18% |
| Network, same turn | 18% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 45 to 59 minutes. How often AA1584’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 LAS late, does that still matter by the time it reaches DFW?
AA1584 pushes back an average of 15.1 minutes late and reaches the gate at DFW an average of 6.5 minutes late. The 8.6 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. Its 19.7 minutes on the taxiways at LAS is about what any departure from the airport in that hour spends.
On arrival at DFW, AA1584 spends 11.2 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 shorter than a typical DFW arrival (13.5 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 DFW. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 33,269 departures from LAS scheduled in the clock hour AA1584 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DFW (961,642 flights), not just AA1584’s own. More on taxi time.

The hour it leaves LAS
Part of any flight’s record belongs to the clock rather than to the flight. AA1584 has one departure time, so this is what that time is worth.
On-time arrival rate. 33,269 departures from LAS are scheduled in the 11 AM–12 PM hour over the period, against 569,617 across the whole day.
AA1584 is scheduled out of LAS at 11:00 AM, in the 11 AM–12 PM bank. Departures from LAS in that hour arrive on time 79.8% of the time against 78.0% across the airport’s whole day, so the hour AA1584 leaves in is an ordinary one for LAS and explains nothing about its record either way.
The two airport figures cover every departure from LAS 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.

Because the same number has served different journeys, the statistics above describe only the route AA1584 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. AA1584 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 703 records of AA1584 operating LAS → DFW, 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.
