Does a late aircraft delay this flight?
How often the plane that flies OO3718 comes in late, and what that does to the departure.
The aircraft flying OO3718 came in 15 or more minutes late on 3% 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: 507 of 621 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 |
|---|---|
| OO3718 | 3% |
| Network, same turn | 17% |
60 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 OO3718’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 TUS?
OO3718 pushes back an average of 2.5 minutes early and reaches the gate at TUS an average of 7.2 minutes early. The 4.7 minutes between those two figures are slack the published schedule already carries. It spends 21.3 minutes on the taxiways at SLC, 1.2 minutes longer than a typical SLC departure in the same hour.
On arrival at TUS, OO3718 spends 4.1 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 about what any arrival at TUS 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 27,718 SLC departures. Taxi-in is landing to gate, set against 60,723 arrivals at TUS. More on taxi time.
