Why F91875 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 F91875 on MCO → LAS. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies F91875 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, F91875 pushed back an average of 20 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 MCO just before it, using the tail number in the DOT file, 656 of 755 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 |
|---|---|---|---|
| F91875 | 28% | 40% | 11% |
| Network, same turn | 23% | 40% | 9% |
The schedule leaves a long gap on the ground, which 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 F91875’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often F91875 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves MCO late, does that still matter by the time it reaches LAS?
F91875 pushes back an average of 9.2 minutes late and reaches the gate at LAS an average of 4.3 minutes early. The 13.5 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 18.6 minutes on the taxiways at MCO, 1.0 minutes longer than a typical MCO departure in the same hour.
On arrival at LAS, F91875 spends 10.5 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 2.8 minutes longer than a typical LAS arrival (7.7 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 LAS. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 31,213 departures from MCO scheduled in the clock hour F91875 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 F91875’s own. More on taxi time.

The hour it leaves MCO
Part of any flight’s record belongs to the clock rather than to the flight. F91875 has one departure time, so this is what that time is worth.
On-time arrival rate. 31,213 departures from MCO are scheduled in the 8 AM–9 AM hour over the period, against 498,221 across the whole day.
F91875 is scheduled out of MCO at 8:15 AM, in the 8 AM–9 AM bank. Departures from MCO in that hour arrive on time 87.8% of the time against 74.8% across the airport’s whole day — the slot alone is worth 13.0 points better before anything about this particular flight is considered.
The two airport figures cover every departure from MCO 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.

Data and methodology
Calculated by FlyerIntel from 763 records of F91875 operating MCO → 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.
