| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 23 January 2026 | 13 hours 10 minutes | Extreme weather |
| 26 January 2026 | 5 hours 53 minutes | Extreme weather |

Delay causes
Why AA 1010 runs late
Late-arriving aircraft accounts for 48% of the 8,694 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 24%Carrier
- 18%Extreme weather
- 10%National Airspace System
Extreme weather accounts for 18% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.0 times the usual weather exposure. The split is drawn from 8,694 delay minutes reported on AA 1010.
Cancellations run at 3.01%, against 1.89% nationally. That is roughly one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
15.9% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 550 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on three other city pairs in the data, including ATL to DCA (1), ATL to MIA (1) and DCA to ATL (1), but none flew often enough under AA 1010 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to STL only.
One caution: this is a thin sample. 332 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking AA 1010
For a booking, the cancellation rate is the figure to plan around on AA 1010: 3.01% of its 332 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
