Why YX4807 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for YX4807 on LGA → MEM. Only delays of 15 minutes or more are attributed. What the five causes mean

Does a late aircraft delay this flight?
How often the plane that flies YX4807 comes in late, and what that does to the departure.
The aircraft flying YX4807 came in 15 or more minutes late on 16% 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 LGA: 634 of 666 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 |
|---|---|
| YX4807 | 16% |
| Network, same turn | 18% |
Little slack sits between the inbound landing and this departure, so a late arrival has almost nowhere to go but into the departure.
The network row is every flight with a scheduled turn of 30 to 44 minutes. How often YX4807’s aircraft landed 15 or more minutes late is about the same as the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves LGA late, does that still matter by the time it reaches MEM?
YX4807 pushes back an average of 7.2 minutes late and reaches the gate at MEM an average of 1.2 minutes early. The 8.4 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. It spends 25.2 minutes on the taxiways at LGA, 3.3 minutes longer than a typical LGA departure in the same hour.
On arrival at MEM, YX4807 spends 7.1 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 1.0 minutes longer than a typical MEM arrival (6.1 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 28,230 LGA departures. Taxi-in is landing to gate, set against 74,887 arrivals at MEM. More on taxi time.

The hour it leaves LGA
YX4807 has one departure time, 12:00 PM, so this is what that hour at LGA is worth.
On-time arrival rate. 28,230 departures from LGA are scheduled in the 12 PM–1 PM hour over the period, against 467,462 across the whole day.
YX4807 is scheduled out of LGA at 12:00 PM, in the 12 PM–1 PM bank. Departures from LGA in that hour arrive on time 81.8% of the time against 78.1% across the airport’s whole day — the slot alone is worth 3.7 points better before anything about this particular flight is considered.
Both airport figures cover every destination from LGA, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.
