Why AA2377 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding, fuelling — within the carrier’s control
weather severe enough to stop this flight specifically
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
Share of the delay minutes US DOT attributed to each cause for AA2377 on SAT → DFW. 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 SAT → DFW
Same airports, same journey — and not the same odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| AA2342 | American Airlines | 90.7% | 10 min early | 1,052 |
| AA1961 | American Airlines | 54.9% | 11 min late | 656 |
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 598 records of AA2377 operating SAT → DFW, 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.
