Why UA1182 runs late
Where US DOT attributed the delay minutes on this flight.
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies UA1182 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, UA1182 pushed back an average of 83 minutes late; when it came in on time or early, an average of 12 minutes late.
Matched by tail number to the aircraft’s previous flight into CMH: 623 of 634 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 |
|---|---|---|---|
| UA1182 | 27% | 82% | 17% |
| Network, same turn | 17% | 69% | 9% |
66 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 UA1182’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often UA1182 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves CMH late, does that still matter by the time it reaches ORD?
UA1182 pushes back an average of 32.5 minutes late and arrives a further 9.6 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 21.0 minutes on the taxiways at CMH, 5.2 minutes longer than a typical CMH departure in the same hour.
On arrival at ORD, UA1182 spends 24.3 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 6.3 minutes longer than a typical ORD arrival (18.0 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 9,305 CMH departures. Taxi-in is landing to gate, set against 985,848 arrivals at ORD. More on taxi time.

UA1182 has one departure time, 5:52 PM, so this is what that hour at CMH is worth.
On-time arrival rate. 9,305 departures from CMH are scheduled in the 5 PM–6 PM hour over the period, against 137,861 across the whole day.
