Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| AA584 | 66.7% | 4.25% | 2 min | 14.4% | 894 |
| American Airlines on TUS → DFW | 80.4% | 2.68% | -6 min | 8.0% | 6,686 |
| All TUS → DFW flights | 80.6% | 2.65% | -6 min | 7.9% | 6,898 |
AA584 has cancelled 4.25% of its scheduled departures (38 of 894), against 2.65% for all TUS → DFW flights — this specific departure cancels 1.6 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 AA584 specifically, not about the route it flies.

Why AA584 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 AA584 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, AA584 pushed back an average of 77 minutes late; when it came in on time or early, an average of 3 minutes late.
Each departure is matched to the flight the same aircraft flew into TUS just before it, using the tail number in the DOT file, 847 of 856 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 | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| AA584 | 29% | 88% | 7% |
| Network, same turn | 18% | 85% | 10% |
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 AA584’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AA584 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves TUS late, does that still matter by the time it reaches DFW?
On arrival at DFW, AA584 spends 14.9 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 1.4 minutes longer 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 2,904 departures from TUS scheduled in the clock hour AA584 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 AA584’s own. More on taxi time.

The hour it leaves TUS
Part of any flight’s record belongs to the clock rather than to the flight. AA584 has one departure time, so this is what that time is worth.
On-time arrival rate. 2,904 departures from TUS are scheduled in the 3 PM–4 PM hour over the period, against 59,292 across the whole day.
AA584 is scheduled out of TUS at 3:40 PM, in the 3 PM–4 PM bank. Departures from TUS in that hour arrive on time 71.6% of the time against 84.3% across the airport’s whole day — the slot alone is worth 12.6 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from TUS 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 AA584 run worse on particular days?
Saturday is historically the most reliable day and Tuesday the least, a gap of 9.8 percentage points.

Other routes AA584 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.
| Route | Operated | Flights | On time |
|---|---|---|---|
| DFW→TUS Dallas–Fort Worth to Tucson | July 1, 2023 – July 31, 2026 | 775 | 69.6% |
| DFW→GRR Dallas–Fort Worth to Grand Rapids | September 6, 2024 | 1 | — |
| GRR→DFW Grand Rapids to Dallas–Fort Worth | September 6, 2024 | 1 | — |
Because the same number has served different journeys, the statistics above describe only the route AA584 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
88 min late
against a median of 2 min late
AA584 has an average that understates its risk: a typical arrival is 2 min late, but the worst tenth are 86 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. AA584 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 894 records of AA584 operating TUS → 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.
