What stands out
How UA1392 compares to other flight numbers, not just to itself.
This flight stays close to typical even on its worst days, a smaller gap than 91% of 11,788 comparable flight numbers.
A typical arrival is 12 min early, and the worst tenth are only 22 minutes worse than that.

Why UA1392 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for UA1392 on MSY → IAD. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies UA1392 comes in late, and what that does to the departure.
UA1392 is usually the aircraft’s first flight of the day: the schedule gives it a median of 10.2 hours on the ground at MSY, so its “inbound” is mostly the aircraft’s arrival the evening before.
The aircraft flying UA1392 came in 15 or more minutes late on 26% 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.
Each departure is matched to the flight the same aircraft flew into MSY just before it, using the tail number in the DOT file, 272 of 756 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 |
|---|---|
| UA1392 | 26% |
| Network, same turn | 29% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less on a turn this long than on a same-day one.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often UA1392’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 MSY late, does that still matter by the time it reaches IAD?
UA1392 pushes back an average of 2.2 minutes late and reaches the gate at IAD an average of 4.2 minutes early. The 6.4 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. Its 12.5 minutes on the taxiways at MSY is about what any departure from the airport in that hour spends.
On arrival at IAD, UA1392 spends 6.7 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 IAD spends on the ground before reaching the gate.
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 IAD. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 6,688 departures from MSY scheduled in the clock hour UA1392 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at IAD (169,930 flights), not just UA1392’s own. More on taxi time.

The hour it leaves MSY
Part of any flight’s record belongs to the clock rather than to the flight. UA1392 has one departure time, so this is what that time is worth.
On-time arrival rate. 6,688 departures from MSY are scheduled in the 8 AM–9 AM hour over the period, against 154,321 across the whole day.
UA1392 is scheduled out of MSY at 8:00 AM, in the 8 AM–9 AM bank. Departures from MSY in that hour arrive on time 89.3% of the time against 78.7% across the airport’s whole day — the slot alone is worth 10.6 points better before anything about this particular flight is considered.
The two airport figures cover every departure from MSY 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 UA1392 currently operates. Blending them would produce an average of two different flights.

Data and methodology
Calculated by FlyerIntel from 765 records of UA1392 operating MSY → IAD, 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.
