Why DL722 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
screening or terminal security incidents
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies DL722 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, DL722 pushed back an average of 30 minutes late; when it came in on time or early, an average of 2 minutes late.
Matched by tail number to the aircraft’s previous flight into LAS: 838 of 846 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 | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| DL722 | 25% | 61% | 7% |
| Network, same turn | 17% | 69% | 9% |
85 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 DL722’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often DL722 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves LAS late, does that still matter by the time it reaches ATL?
DL722 pushes back an average of 10.0 minutes late and reaches the gate at ATL an average of 1.0 minutes late. The 9.0 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. It spends 14.6 minutes on the taxiways at LAS, 1.0 minutes shorter than a typical LAS departure in the same hour.
On arrival at ATL, DL722 spends 7.3 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 2.3 minutes shorter than a typical ATL arrival (9.6 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 21,866 LAS departures. Taxi-in is landing to gate, set against 1,039,387 arrivals at ATL. More on taxi time.

The hour it leaves LAS
DL722 has one departure time, 11:45 PM, so this is what that hour at LAS is worth.
On-time arrival rate. 21,866 departures from LAS are scheduled in the 11 PM–12 AM hour over the period, against 583,449 across the whole day.
DL722 is scheduled out of LAS at 11:45 PM, in the 11 PM–12 AM bank. Departures from LAS in that hour arrive on time 80.3% of the time against 77.8% across the airport’s whole day, so the hour DL722 leaves in is an ordinary one for LAS and explains nothing about its record either way.
Both airport figures cover every destination from LAS, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

By day of week
Does DL722 run worse on particular days?
Monday scored highest and Sunday lowest, 8.0 points apart, but with about 124 operations per scored day that is within what chance alone produces, so no day stands out.

Data and methodology
Calculated by FlyerIntel from 857 records of DL722 operating LAS → ATL, 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.
