Why UA2326 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 UA2326 comes in late, and what that does to the departure.
UA2326 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8 hours on the ground at ORD, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, UA2326 pushed back an average of 3 minutes late; when it came in on time or early, an average of 2 minutes early.
Each departure is matched to the flight the same aircraft flew into ORD just before it, using the tail number in the DOT file, 748 of 885 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 |
|---|---|---|---|
| UA2326 | 16% | 14% | 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 UA2326’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often UA2326 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves ORD late, does that still matter by the time it reaches TPA?
UA2326 pushes back an average of 0.2 minutes early and reaches the gate at TPA an average of 5.6 minutes early. The 5.4 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. It spends 26.8 minutes on the taxiways at ORD, 2.5 minutes longer than a typical ORD departure in the same hour.
On arrival at TPA, UA2326 spends 5.7 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 TPA 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 TPA. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 67,479 departures from ORD scheduled in the clock hour UA2326 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at TPA (242,635 flights), not just UA2326’s own. More on taxi time.

The hour it leaves ORD
Part of any flight’s record belongs to the clock rather than to the flight. UA2326 has one departure time, so this is what that time is worth.
On-time arrival rate. 67,479 departures from ORD are scheduled in the 7 AM–8 AM hour over the period, against 952,802 across the whole day.
UA2326 is scheduled out of ORD at 7:30 AM, in the 7 AM–8 AM bank. Departures from ORD in that hour arrive on time 86.6% of the time against 74.5% across the airport’s whole day — the slot alone is worth 12.1 points better before anything about this particular flight is considered.
The two airport figures cover every departure from ORD 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 UA2326 run worse on particular days?
Monday is historically the most reliable day and Saturday the least, a gap of 15.8 percentage points.

Because the same number has served different journeys, the statistics above describe only the route UA2326 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. UA2326 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 895 records of UA2326 operating ORD → TPA, 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.
