Does a late aircraft delay this flight?

How often the plane that flies UA1418 comes in late, and what that does to the departure.

Inbound aircraft late
8%
57 of 714 departures came in 15+ minutes late
Scheduled time on the ground
75 minutes
Median at DEN between the inbound and this departure

The aircraft flying UA1418 came in 15 or more minutes late on 8% 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 DEN: 714 of 797 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.

Against the network at the same turn length

75 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 UA1418’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 DEN late, does that still matter by the time it reaches MIA?

Leaves the gate
10.8 minutes late
Average over 797 pushbacks

Taxi in at MIA

Reaches the gate at MIA
13.0 minutes late
Average over 795 arrivals

UA1418 pushes back an average of 10.8 minutes late and arrives a further 2.2 minutes behind that. This departure loses ground between the two gates rather than recovering it, so a late pushback here tends to get worse on the way, not better. It spends 24.5 minutes on the taxiways at DEN, 4.0 minutes longer than a typical DEN departure in the same hour.

On arrival at MIA, UA1418 spends 13.8 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 4.0 minutes longer than a typical MIA arrival (9.7 min).

Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 61,874 DEN departures. Taxi-in is landing to gate, set against 349,140 arrivals at MIA. More on taxi time.
