Why UA2474 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for UA2474 on IAH → MSY. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies UA2474 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, UA2474 pushed back an average of 35 minutes late; when it came in on time or early, an average of 0 minutes early.
Each departure is matched to the flight the same aircraft flew into IAH just before it, using the tail number in the DOT file, 583 of 668 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 |
|---|---|---|---|
| UA2474 | 21% | 50% | 9% |
| Network, same turn | 23% | 40% | 9% |
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 90 minutes to 3 hours. How often UA2474’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often UA2474 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 MSY?
UA2474 pushes back an average of 8.1 minutes late and reaches the gate at MSY an average of 1.2 minutes late. The 6.8 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. Its 17.2 minutes on the taxiways at IAH is about what any departure from the airport in that hour spends.
On arrival at MSY, UA2474 spends 3.9 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 1.5 minutes shorter than a typical MSY arrival (5.4 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 MSY. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 4,383 departures from IAH scheduled in the clock hour UA2474 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at MSY (154,323 flights), not just UA2474’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. UA2474 has one departure time, so this is what that time is worth.
On-time arrival rate. 4,383 departures from IAH are scheduled in the 10 PM–11 PM hour over the period, against 359,450 across the whole day.
UA2474 is scheduled out of IAH at 10:15 PM, in the 10 PM–11 PM bank. Departures from IAH in that hour arrive on time 77.2% of the time against 77.4% across the airport’s whole day, so the hour UA2474 leaves in is an ordinary one for IAH and explains nothing about its record either way.
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.

Because the same number has served different journeys, the statistics above describe only the route UA2474 currently operates. Blending them would produce an average of two different flights.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. UA2474 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 675 records of UA2474 operating IAH → MSY, 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.
