Why UA1207 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 UA1207 comes in late, and what that does to the departure.
UA1207 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8.3 hours on the ground at EWR, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, UA1207 pushed back an average of 3 minutes early; when it came in on time or early, an average of 3 minutes early.
Each departure is matched to the flight the same aircraft flew into EWR just before it, using the tail number in the DOT file, 658 of 862 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 |
|---|---|---|---|
| UA1207 | 34% | 6% | 5% |
| Network, same turn | 29% | 12% | 9% |
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 UA1207’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often UA1207 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves EWR late, does that still matter by the time it reaches JAX?
UA1207 pushes back an average of 0.7 minutes early and reaches the gate at JAX an average of 6.5 minutes early. The 5.8 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. It spends 22.5 minutes on the taxiways at EWR, 1.5 minutes longer than a typical EWR departure in the same hour.
On arrival at JAX, UA1207 spends 5.8 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 1.0 minutes shorter than a typical JAX arrival (6.8 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 JAX. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 31,762 departures from EWR scheduled in the clock hour UA1207 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at JAX (90,311 flights), not just UA1207’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. UA1207 has one departure time, so this is what that time is worth.
On-time arrival rate. 31,762 departures from EWR are scheduled in the 6 AM–7 AM hour over the period, against 387,621 across the whole day.
UA1207 is scheduled out of EWR at 6:00 AM, in the 6 AM–7 AM bank. Departures from EWR in that hour arrive on time 89.2% of the time against 77.7% across the airport’s whole day — the slot alone is worth 11.6 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.

By day of week
Does UA1207 run worse on particular days?
Tuesday is historically the most reliable day and Monday the least, a gap of 5.7 percentage points.

Data and methodology
Calculated by FlyerIntel from 878 records of UA1207 operating EWR → JAX, 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.
