Across the year
AA 1371 quarter by quarter
AA 1371 did not run the same all year. Its best quarter was Apr–Jun 2026 at 58.1% on time and its weakest Jul–Sep 2026 at 45.8%, a swing of 12 points on roughly 90 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Share of 347 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 154 departures that left 15 minutes late or more, only 17 made it up before arrival. In the other direction, 24 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at DSM.

The latest arrival of the period was on 10 March 2026, 12 hours behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Three of the five worst days fell in July 2026.

| 10 March 2026 | 12 hours | Carrier |

Delay causes
Why AA 1371 runs late
Carrier accounts for 46% of the 15,000 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Carrier
- 40%Late-arriving aircraft
- 8%National Airspace System
- 6%Extreme weather
- 0%Security
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 15,000 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 14,548 delay minutes reported on AA 1371.
Cancellations run at 3.33%, against 1.89% nationally. That is about 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
19.3% 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 624 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.
Every one of the 360 flights under AA 1371 in the data flew DFW to DSM. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 360 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 1371
For a booking, the cancellation rate is the figure to plan around on AA 1371: 3.33% of its 360 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
