Why UA1312 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding, fuelling — within the carrier’s control
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for UA1312 on IAH → TPA. 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 IAH → TPA

|---|---|---|---|---|
| UA2260 | United Airlines | 89.9% | 13 min early | 704 |
| UA2093 | United Airlines | 71.8% | 2 min early | 633 |

Data and methodology
Calculated by FlyerIntel from 278 records of UA1312 operating IAH → 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.
