Why DL484 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies DL484 comes in late, and what that does to the departure.
DL484 is usually the aircraft’s first flight of the day: the schedule gives it a median of 6.5 hours on the ground at MCO, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, DL484 pushed back an average of 6 minutes late; when it came in on time or early, an average of 0 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, 684 of 780 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 |
|---|---|---|---|
| DL484 | 22% | 13% | 5% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less on a turn this long than on a same-day one.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often DL484’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often DL484 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 LAX?
DL484 pushes back an average of 1.5 minutes late and reaches the gate at LAX an average of 7.2 minutes early. The 8.7 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 19.5 minutes on the taxiways at MCO, 2.6 minutes longer than a typical MCO departure in the same hour.
On arrival at LAX, DL484 spends 12.6 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 1.9 minutes longer than a typical LAX arrival (10.7 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 LAX. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 34,781 departures from MCO scheduled in the clock hour DL484 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at LAX (595,170 flights), not just DL484’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. DL484 has one departure time, so this is what that time is worth.
On-time arrival rate. 34,781 departures from MCO are scheduled in the 6 AM–7 AM hour over the period, against 498,221 across the whole day.
DL484 is scheduled out of MCO at 6:00 AM, in the 6 AM–7 AM bank. Departures from MCO in that hour arrive on time 92.2% of the time against 74.8% across the airport’s whole day — the slot alone is worth 17.4 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.

Because the same number has served different journeys, the statistics above describe only the route DL484 currently operates. Blending them would produce an average of two different flights.

Same airports, same journey, different odds of arriving on time.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL484 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 785 records of DL484 operating MCO → LAX, 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.
