Why DL1244 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

Does a late aircraft delay this flight?
How often the plane that flies DL1244 comes in late, and what that does to the departure.
The aircraft flying DL1244 came in 15 or more minutes late on 13% 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 SLC: 584 of 612 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 |
|---|---|
| DL1244 | 13% |
| Network, same turn | 17% |
65 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 60 to 89 minutes. How often DL1244’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 SLC late, does that still matter by the time it reaches PDX?
DL1244 pushes back an average of 6.5 minutes late and reaches the gate at PDX an average of 1.5 minutes early. The 8.0 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 14.7 minutes on the taxiways at SLC, 2.9 minutes shorter than a typical SLC departure in the same hour.
On arrival at PDX, DL1244 spends 4.2 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 about what any arrival at PDX spends on the ground before reaching the gate.
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 33,608 SLC departures. Taxi-in is landing to gate, set against 193,821 arrivals at PDX. More on taxi time.

The hour it leaves SLC
DL1244 has one departure time, 3:25 PM, so this is what that hour at SLC is worth.
On-time arrival rate. 33,608 departures from SLC are scheduled in the 3 PM–4 PM hour over the period, against 365,355 across the whole day.
DL1244 is scheduled out of SLC at 3:25 PM, in the 3 PM–4 PM bank. Departures from SLC in that hour arrive on time 83.4% of the time against 83.9% across the airport’s whole day, so the hour DL1244 leaves in is an ordinary one for SLC and explains nothing about its record either way.
Both airport figures cover every destination from SLC, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

Data and methodology
Calculated by FlyerIntel from 616 records of DL1244 operating SLC → PDX, 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 reported separately, not in the on-time rate.
