Why UA708 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies UA708 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, UA708 pushed back an average of 35 minutes late; 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 MCI just before it, using the tail number in the DOT file, 916 of 944 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 |
|---|---|---|---|
| UA708 | 15% | 58% | 4% |
| Network, same turn | 17% | 68% | 9% |
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 UA708’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often UA708 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves MCI late, does that still matter by the time it reaches DEN?
UA708 pushes back an average of 4.2 minutes late and reaches the gate at DEN an average of 3.1 minutes early. The 7.3 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 17.1 minutes on the taxiways at MCI, 3.1 minutes longer than a typical MCI departure in the same hour.
On arrival at DEN, UA708 spends 8.1 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 1.7 minutes shorter 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 8,418 departures from MCI scheduled in the clock hour UA708 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 UA708’s own. More on taxi time.

The hour it leaves MCI
Part of any flight’s record belongs to the clock rather than to the flight. UA708 has one departure time, so this is what that time is worth.
On-time arrival rate. 8,418 departures from MCI are scheduled in the 1 PM–2 PM hour over the period, against 152,682 across the whole day.
UA708 is scheduled out of MCI at 1:50 PM, in the 1 PM–2 PM bank. Departures from MCI in that hour arrive on time 80.9% of the time against 81.0% across the airport’s whole day, so the hour UA708 leaves in is an ordinary one for MCI and explains nothing about its record either way.
The two airport figures cover every departure from MCI 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 UA708 run worse on particular days?
Wednesday is historically the most reliable day and Friday the least, a gap of 11.6 percentage points.

Because the same number has served different journeys, the statistics above describe only the route UA708 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. UA708 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 947 records of UA708 operating MCI → 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.
