Why DL2592 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 DL2592 comes in late, and what that does to the departure.
DL2592 is usually the aircraft’s first flight of the day: the schedule gives it a median of 7.1 hours on the ground at SAT, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, DL2592 pushed back an average of 22 minutes late; when it came in on time or early, an average of 2 minutes early.
Matched by tail number to the aircraft’s previous flight into SAT: 595 of 615 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 |
|---|---|---|---|
| DL2592 | 21% | 12% | 6% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less here than on a same-day turn.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often DL2592’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often DL2592 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves SAT late, does that still matter by the time it reaches SLC?
DL2592 pushes back an average of 5.8 minutes late and reaches the gate at SLC an average of 3.1 minutes early. The 8.9 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. Its 13.4 minutes on the taxiways at SAT is about what any departure from the airport in that hour spends.
On arrival at SLC, DL2592 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 about what any arrival at SLC 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 10,920 SAT departures. Taxi-in is landing to gate, set against 365,173 arrivals at SLC. More on taxi time.

The hour it leaves SAT
DL2592 has one departure time, 5:30 AM, so this is what that hour at SAT is worth.
On-time arrival rate. 10,920 departures from SAT are scheduled in the 5 AM–6 AM hour over the period, against 130,520 across the whole day.
DL2592 is scheduled out of SAT at 5:30 AM, in the 5 AM–6 AM bank. Departures from SAT in that hour arrive on time 93.6% of the time against 82.3% across the airport’s whole day — the slot alone is worth 11.3 points better before anything about this particular flight is considered.
Both airport figures cover every destination from SAT, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.
