Why AA1771 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 AA1771 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, AA1771 pushed back an average of 60 minutes late; when it came in on time or early, an average of 16 minutes late.
Each departure is matched to the flight the same aircraft flew into DFW just before it, using the tail number in the DOT file, 722 of 820 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 |
|---|---|---|---|
| AA1771 | 31% | 76% | 28% |
| Network, same turn | 17% | 68% | 9% |
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 60 to 89 minutes. How often AA1771’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AA1771 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves DFW late, does that still matter by the time it reaches LAS?
AA1771 pushes back an average of 40.0 minutes late and reaches the gate at LAS an average of 36.6 minutes late. The 3.4 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 18.9 minutes on the taxiways at DFW is about what any departure from the airport in that hour spends.
On arrival at LAS, AA1771 spends 8.3 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 LAS spends on the ground before reaching the gate.
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 LAS. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 59,301 departures from DFW scheduled in the clock hour AA1771 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at LAS (569,643 flights), not just AA1771’s own. More on taxi time.

The hour it leaves DFW
Part of any flight’s record belongs to the clock rather than to the flight. AA1771 has one departure time, so this is what that time is worth.
On-time arrival rate. 59,301 departures from DFW are scheduled in the 6 PM–7 PM hour over the period, against 961,718 across the whole day.
AA1771 is scheduled out of DFW at 6:53 PM, in the 6 PM–7 PM bank. Departures from DFW in that hour arrive on time 64.2% of the time against 73.1% across the airport’s whole day — the slot alone is worth 8.9 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from DFW 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.

Other routes AA1771 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.

Because the same number has served different journeys, the statistics above describe only the route AA1771 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.
108 min late
against a median of 12 min late
AA1771 has an average that understates its risk: a typical arrival is 12 min late, but the worst tenth are 96 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. AA1771 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 841 records of AA1771 operating DFW → LAS, 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.
