Why F93229 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies F93229 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, F93229 pushed back an average of 26 minutes late; when it came in on time or early, an average of 4 minutes late.
Each departure is matched to the flight the same aircraft flew into IAH just before it, using the tail number in the DOT file, 854 of 876 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
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 |
|---|---|---|---|
| F93229 | 28% | 30% | 11% |
| Network, same turn | 33% | 24% | 11% |
The schedule leaves a long gap on the ground, which gives a late aircraft room to catch up before this flight pushes back.
The network row is every flight with a scheduled turn of 3 to 6 hours. How often F93229’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often F93229 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves IAH late, does that still matter by the time it reaches DEN?
F93229 pushes back an average of 13.5 minutes late and reaches the gate at DEN an average of 9.1 minutes late. The 4.4 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 18.5 minutes on the taxiways at IAH, 3.0 minutes longer than a typical IAH departure in the same hour.
On arrival at DEN, F93229 spends 13.8 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 4.0 minutes longer than a typical DEN arrival (9.8 min).
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached DEN. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 14,228 departures from IAH scheduled in the clock hour F93229 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DEN (963,027 flights), not just F93229’s own. More on taxi time.

The hour it leaves IAH
Part of any flight’s record belongs to the clock rather than to the flight. F93229 has one departure time, so this is what that time is worth.
On-time arrival rate. 14,228 departures from IAH are scheduled in the 6 AM–7 AM hour over the period, against 359,450 across the whole day.
F93229 is scheduled out of IAH at 6:00 AM, in the 6 AM–7 AM bank. Departures from IAH in that hour arrive on time 88.3% of the time against 77.4% across the airport’s whole day — the slot alone is worth 10.8 points better before anything about this particular flight is considered.
The two airport figures cover every departure from IAH to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

Does F93229 run worse on particular days?
Friday is historically the most reliable day and Monday the least, a gap of 14.2 percentage points.

Same airports, same journey, different odds of arriving on time.

|---|---|---|---|---|

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. F93229 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 887 records of F93229 operating IAH → DEN, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
