These figures cover 289 flights between September 2025 and August 2026. The median arrival is 17 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

The latest arrival of the period was on 30 August 2026, 25 hours 50 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 30 August 2026 | 25 hours 50 minutes | Carrier |
| 4 May 2026 | 22 hours 55 minutes | Carrier |
| 18 August 2026 | 11 hours 49 minutes | Carrier |

Delay causes
Why AA 1940 runs late
Carrier accounts for 79% of the 5,970 delay minutes carriers reported here, and the remaining four split what is left.
- 79%Carrier
- 10%National Airspace System
- 8%Extreme weather
- 3%Late-arriving aircraft
The largest share of delay minutes, 79%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 4,700 of the 5,970 delay minutes reported here. The split is drawn from 5,970 delay minutes reported on AA 1940.
Cancellations run at 3.81%, against 1.89% nationally. That is about one flight in 25 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
5.4% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 3.4 hours, which a normal layover absorbs.
The same number turns up on one other city pair in the data, including DFW to SJC (75), but none flew often enough under AA 1940 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MEM to DFW only.
One caution: this is a thin sample. 289 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 1940
For a booking, the cancellation rate is the figure to plan around on AA 1940: 3.81% of its 289 scheduled flights did not operate. A late arrival costs about 3.4 hours, but a cancellation costs the day, so leave a later option open.
