Because the same number has served different journeys, the statistics above describe only the route UA2334 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
17 min late
against a median of 17 min early
Percentiles over 431 operations. Cancelled and diverted flights have no arrival time and are counted separately rather than as very late arrivals.
Why UA2334 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, fuelling — within the carrier’s control
Share of the delay minutes US DOT attributed to each cause for UA2334 on PDX → DEN. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.
Other departures on PDX → DEN
Same airports, same journey — and not the same odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| UA459 | United Airlines | 96.3% | 14 min early | 767 |
| F91790 | Frontier Airlines | 79.7% | 4 min early | 821 |
Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 431 records of UA2334 operating PDX → 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.
