Why F91876 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
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 F91876 on LAS → MCO. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies F91876 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, F91876 pushed back an average of 41 minutes late; when it came in on time or early, an average of 13 minutes late.
Each departure is matched to the flight the same aircraft flew into LAS just before it, using the tail number in the DOT file, 734 of 832 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 |
|---|---|---|---|
| F91876 | 29% | 56% | 22% |
| 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 F91876’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often F91876 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves LAS late, does that still matter by the time it reaches MCO?
F91876 pushes back an average of 21.3 minutes late and reaches the gate at MCO an average of 10.7 minutes late. The 10.6 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. It spends 17.4 minutes on the taxiways at LAS, 1.8 minutes longer than a typical LAS departure in the same hour.
On arrival at MCO, F91876 spends 12.5 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 1.6 minutes longer than a typical MCO arrival (10.9 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 MCO. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 21,416 departures from LAS scheduled in the clock hour F91876 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at MCO (498,229 flights), not just F91876’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. F91876 has one departure time, so this is what that time is worth.
On-time arrival rate. 21,416 departures from LAS are scheduled in the 11 PM–12 AM hour over the period, against 569,617 across the whole day.
F91876 is scheduled out of LAS at 11:03 PM, in the 11 PM–12 AM bank. Departures from LAS in that hour arrive on time 80.4% of the time against 78.0% across the airport’s whole day, so the hour F91876 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.

By day of week
Does F91876 run worse on particular days?
Saturday is historically the most reliable day and Friday the least, a gap of 16.3 percentage points.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
57 min late
against a median of 4 min early
F91876 has an average that understates its risk: a typical arrival is 4 min early, but the worst tenth are 61 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Data and methodology
Calculated by FlyerIntel from 841 records of F91876 operating LAS → MCO, 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.
