Why F92631 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for F92631 on DFW → DEN. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies F92631 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, F92631 pushed back an average of 61 minutes late; when it came in on time or early, an average of 2 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, 537 of 627 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 |
|---|---|---|---|
| F92631 | 23% | 75% | 9% |
| 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 F92631’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often F92631 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 DEN?
F92631 pushes back an average of 22.1 minutes late and reaches the gate at DEN an average of 19.0 minutes late. The 3.0 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. It spends 22.8 minutes on the taxiways at DFW, 5.3 minutes longer than a typical DFW departure in the same hour.
On arrival at DEN, F92631 spends 14.0 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 4.2 minutes longer than a typical DEN arrival (9.8 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 DEN. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 15,233 departures from DFW scheduled in the clock hour F92631 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DEN (963,027 flights), not just F92631’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. F92631 has one departure time, so this is what that time is worth.
On-time arrival rate. 15,233 departures from DFW are scheduled in the 6 AM–7 AM hour over the period, against 961,718 across the whole day.
F92631 is scheduled out of DFW at 6:15 AM, in the 6 AM–7 AM bank. Departures from DFW in that hour arrive on time 85.5% of the time against 73.1% across the airport’s whole day — the slot alone is worth 12.4 points better 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 F92631 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 |
|---|---|---|---|
| PHL→DFW Philadelphia to Dallas–Fort Worth | July 12, 2024 – August 2, 2024 | 5 | — |
Because the same number has served different journeys, the statistics above describe only the route F92631 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.
77 min late
against a median of 6 min early
F92631 has an average that understates its risk: a typical arrival is 6 min early, but the worst tenth are 83 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. F92631 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 638 records of F92631 operating DFW → DEN, 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.
