Why UA1739 runs late
Where US DOT attributed the delay minutes on this flight.
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies UA1739 comes in late, and what that does to the departure.
The aircraft flying UA1739 came in 15 or more minutes late on 13% 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 EWR just before it, using the tail number in the DOT file, 534 of 646 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 |
|---|---|
| UA1739 | 13% |
| Network, same turn | 17% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often UA1739’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves EWR late, does that still matter by the time it reaches MCO?
UA1739 pushes back an average of 9.4 minutes late and reaches the gate at MCO an average of 2.8 minutes late. The 6.6 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 26.8 minutes on the taxiways at EWR, 2.8 minutes longer than a typical EWR departure in the same hour.
On arrival at MCO, UA1739 spends 9.0 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 1.9 minutes shorter than a typical MCO arrival (10.9 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 MCO. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 23,655 departures from EWR scheduled in the clock hour UA1739 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at MCO (498,229 flights), not just UA1739’s own. More on taxi time.

The hour it leaves EWR
Part of any flight’s record belongs to the clock rather than to the flight. UA1739 has one departure time, so this is what that time is worth.
On-time arrival rate. 23,655 departures from EWR are scheduled in the 10 AM–11 AM hour over the period, against 387,621 across the whole day.
UA1739 is scheduled out of EWR at 10:30 AM, in the 10 AM–11 AM bank. Departures from EWR in that hour arrive on time 82.3% of the time against 77.7% across the airport’s whole day — the slot alone is worth 4.6 points better before anything about this particular flight is considered.
The two airport figures cover every departure from EWR 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 UA1739 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. UA1739 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 664 records of UA1739 operating EWR → MCO, 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.
