What stands out
How DL2419 compares to other flight numbers, not just to itself.
This flight stays close to typical even on its worst days, a smaller gap than 93% of 11,788 comparable flight numbers.
A typical arrival is 15 min early, and the worst tenth are only 21 minutes worse than that.

Why DL2419 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
Share of the delay minutes US DOT attributed to each cause for DL2419 on PHX → SEA. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies DL2419 comes in late, and what that does to the departure.
The aircraft flying DL2419 came in 15 or more minutes late on 9% 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 PHX just before it, using the tail number in the DOT file, 773 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 |
|---|---|
| DL2419 | 9% |
| Network, same turn | 18% |
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 45 to 59 minutes. How often DL2419’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 PHX late, does that still matter by the time it reaches SEA?
DL2419 pushes back an average of 0.9 minutes late and reaches the gate at SEA an average of 10.4 minutes early. The 11.3 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. Its 14.5 minutes on the taxiways at PHX is about what any departure from the airport in that hour spends.
On arrival at SEA, DL2419 spends 12.9 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 1.1 minutes longer 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 31,612 departures from PHX scheduled in the clock hour DL2419 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 DL2419’s own. More on taxi time.

The hour it leaves PHX
Part of any flight’s record belongs to the clock rather than to the flight. DL2419 has one departure time, so this is what that time is worth.
On-time arrival rate. 31,612 departures from PHX are scheduled in the 12 PM–1 PM hour over the period, against 598,518 across the whole day.
DL2419 is scheduled out of PHX at 12:05 PM, in the 12 PM–1 PM bank. Departures from PHX in that hour arrive on time 80.0% of the time against 80.3% across the airport’s whole day, so the hour DL2419 leaves in is an ordinary one for PHX and explains nothing about its record either way.
The two airport figures cover every departure from PHX 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 DL2419 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 |
|---|---|---|---|
| SEA→PHX Seattle to Phoenix | June 7, 2024 – July 31, 2026 | 784 | 91.0% |
| ATL→BTV Atlanta to Burlington | September 5, 2023 – June 6, 2024 | 200 | 89.0% |
| STL→DTW St. Louis to Detroit | July 5, 2023 – September 4, 2023 | 49 | — |
Because the same number has served different journeys, the statistics above describe only the route DL2419 currently operates. Blending them would produce an average of two different flights.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL2419 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 DL2419 operating PHX → 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.
