Why DL2449 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 DL2449 on PHX → SEA. Only delays of 15 minutes or more are attributed. What the five causes mean

Does a late aircraft delay this flight?
How often the plane that flies DL2449 comes in late, and what that does to the departure.
The aircraft flying DL2449 came in 15 or more minutes late on 17% 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.
Matched by tail number to the aircraft’s previous flight into PHX: 590 of 595 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late |
|---|---|
| DL2449 | 17% |
| Network, same turn | 18% |
56 scheduled minutes is enough to clean and board when the aircraft is on time, with little to spare when it is not.
The network row is every flight with a scheduled turn of 45 to 59 minutes. How often DL2449’s aircraft landed 15 or more minutes late is about the same as 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?
DL2449 pushes back an average of 7.8 minutes late and reaches the gate at SEA an average of 3.1 minutes early. The 10.9 minutes between those two figures are slack the published schedule already carries, so on average a late pushback on this flight is made up before the gate. It spends 13.4 minutes on the taxiways at PHX, 1.2 minutes shorter than a typical PHX departure in the same hour.
On arrival at SEA, DL2449 spends 10.8 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 1.2 minutes shorter than a typical SEA arrival (11.9 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 38,263 PHX departures. Taxi-in is landing to gate, set against 526,096 arrivals at SEA. More on taxi time.
