Why DL2811 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
Share of the delay minutes US DOT attributed to each cause for DL2811 on SLC → DFW. 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 DL2811 comes in late, and what that does to the departure.
The aircraft flying DL2811 came in 15 or more minutes late on 14% 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: 552 of 605 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 |
|---|---|
| DL2811 | 14% |
| Network, same turn | 18% |
58 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 DL2811’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 DFW?
DL2811 pushes back an average of 13.7 minutes late and reaches the gate at DFW an average of 9.5 minutes late. The 4.2 minutes between those two figures are slack the published schedule already carries, so a late pushback is partly, not fully, made up before the gate. Its 16.2 minutes on the taxiways at SLC is about what any departure from the airport in that hour spends.
On arrival at DFW, DL2811 spends 12.1 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 1.5 minutes shorter than a typical DFW arrival (13.6 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 22,358 SLC departures. Taxi-in is landing to gate, set against 988,998 arrivals at DFW. More on taxi time.

The hour it leaves SLC
DL2811 has one departure time, 1:50 PM, so this is what that hour at SLC is worth.
On-time arrival rate. 22,358 departures from SLC are scheduled in the 1 PM–2 PM hour over the period, against 365,355 across the whole day.
DL2811 is scheduled out of SLC at 1:50 PM, in the 1 PM–2 PM bank. Departures from SLC in that hour arrive on time 81.9% of the time against 83.9% across the airport’s whole day, so the hour DL2811 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 612 records of DL2811 operating SLC → DFW, 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.
