These figures cover 362 flights between September 2025 and August 2026. The median arrival is 11 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.

Delay causes
Why AA 1226 runs late
Carrier accounts for 62% of the 2,743 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Carrier
- 23%Late-arriving aircraft
- 14%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 62%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,700 of the 2,743 delay minutes reported here. The split is drawn from 2,743 delay minutes reported on AA 1226.
Cancellations run at 3.31%, 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
Badly late arrivals are rare here: only 3.4% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 1,121 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 362 flights under AA 1226 in the data flew MIA to DFW. 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. 362 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 1226
For a booking, the cancellation rate is the figure to plan around on AA 1226: 3.31% of its 362 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.
