The aircraft flying WN33 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 DAL: 680 of 702 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.

WN33 pushes back an average of 15.9 minutes late and reaches the gate at HOU an average of 10.7 minutes late. The 5.2 minutes between those two figures are slack the published schedule already carries, so a late pushback is partly, not fully, made up before the gate. It spends 15.6 minutes on the taxiways at DAL, 1.7 minutes longer than a typical DAL departure in the same hour.

On arrival at HOU, WN33 spends 5.2 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 HOU 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 13,905 DAL departures. Taxi-in is landing to gate, set against 176,532 arrivals at HOU. More on taxi time.

WN33 is scheduled out of DAL at 2:30 PM, in the 2 PM–3 PM bank. Departures from DAL in that hour arrive on time 75.3% of the time against 75.9% across the airport’s whole day, so the hour WN33 leaves in is an ordinary one for DAL and explains nothing about its record either way.

Both airport figures cover every destination from DAL, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.
