Why AS419 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 AS419 comes in late, and what that does to the departure.
The aircraft flying AS419 came in 15 or more minutes late on 11% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Each departure is matched to the flight the same aircraft flew into MCO just before it, using the tail number in the DOT file, 616 of 636 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 |
|---|---|
| AS419 | 11% |
| Network, same turn | 17% |
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 AS419’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves MCO late, does that still matter by the time it reaches SEA?
AS419 pushes back an average of 13.1 minutes late and reaches the gate at SEA an average of 6.1 minutes late. The 7.0 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 23.7 minutes on the taxiways at MCO, 2.3 minutes longer than a typical MCO departure in the same hour.
On arrival at SEA, AS419 spends 10.6 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 1.3 minutes shorter than a typical SEA arrival (11.9 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 SEA. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 28,355 departures from MCO scheduled in the clock hour AS419 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at SEA (510,187 flights), not just AS419’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. AS419 has one departure time, so this is what that time is worth.
On-time arrival rate. 28,355 departures from MCO are scheduled in the 4 PM–5 PM hour over the period, against 498,221 across the whole day.
AS419 is scheduled out of MCO at 4:39 PM, in the 4 PM–5 PM bank. Departures from MCO in that hour arrive on time 65.2% of the time against 74.8% across the airport’s whole day — the slot alone is worth 9.6 points worse 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.

Other routes AS419 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 |
|---|---|---|---|
| PDX→SAN Portland to San Diego | August 21, 2024 – January 5, 2025 | 105 | 83.7% |
| SEA→BZN Seattle to Bozeman | June 13, 2024 – August 19, 2024 | 68 | — |
| IAD→SEA Washington to Seattle | May 16, 2024 – June 12, 2024 | 28 | — |
| DTW→SEA Detroit to Seattle | July 1, 2023 – September 30, 2023 | 92 | 72.8% |
| SEA→DTW Seattle to Detroit | July 1, 2023 – September 5, 2023 | 67 | — |
Because the same number has served different journeys, the statistics above describe only the route AS419 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.
51 min late
against a median of 9 min early
AS419 has an average that understates its risk: a typical arrival is 9 min early, but the worst tenth are 60 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. AS419 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 648 records of AS419 operating MCO → SEA, 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.
