Does a late aircraft delay this flight?
How often the plane that flies YX3430 comes in late, and what that does to the departure.
YX3430 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8 hours on the ground at CMH, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, YX3430 pushed back an average of 1 minute late; when it came in on time or early, an average of 1 minute early.
Matched by tail number to the aircraft’s previous flight into CMH: 878 of 1,050 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 |
|---|---|---|---|
| YX3430 | 19% | 11% | 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 YX3430’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often YX3430 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves CMH late, does that still matter by the time it reaches IAD?
YX3430 pushes back an average of 0.4 minutes early and reaches the gate at IAD an average of 6.9 minutes early. The 6.4 minutes between those two figures are slack the published schedule already carries. Its 16.8 minutes on the taxiways at CMH is about what any departure from the airport in that hour spends.
On arrival at IAD, YX3430 spends 9.1 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 1.6 minutes longer than a typical IAD arrival (7.5 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 18,797 CMH departures. Taxi-in is landing to gate, set against 174,895 arrivals at IAD. More on taxi time.

The hour it leaves CMH
YX3430 has one departure time, 6:00 AM, so this is what that hour at CMH is worth.
On-time arrival rate. 18,797 departures from CMH are scheduled in the 6 AM–7 AM hour over the period, against 137,861 across the whole day.
YX3430 is scheduled out of CMH at 6:00 AM, in the 6 AM–7 AM bank. Departures from CMH in that hour arrive on time 91.3% of the time against 82.0% across the airport’s whole day — the slot alone is worth 9.3 points better before anything about this particular flight is considered.
Both airport figures cover every destination from CMH, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

By day of week
Does YX3430 run worse on particular days?
