UA2224 pushes back an average of 19.3 minutes late and reaches the gate at DCA an average of 12.7 minutes late. The 6.6 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 21.0 minutes on the taxiways at IAH, 1.4 minutes longer than a typical IAH departure in the same hour.

On arrival at DCA, UA2224 spends 7.8 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 about what any arrival at DCA 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 19,456 IAH departures. Taxi-in is landing to gate, set against 447,280 arrivals at DCA. More on taxi time.
