AA 1226 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 362 flights, with a median arrival 8 minutes early.
Set against the rest of the country, AA 1226's record is 12 points better than the US average of 77.6%. That gap is worth roughly 117 fewer late arrivals for every thousand flights.

These figures cover 362 flights between July 2025 and June 2026. The median arrival is 8 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.
Schedule
When AA 1226 flies
AA 1226 flies MIA to DFW without a single fixed slot. Its most common scheduled departure was 05:18, used on 99 of 362 flights, with 05:00 (87 flights) and 05:15 (63 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 05:18 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and AA 1226 runs level with that at 89.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

By weekday, AA 1226 ranged from 85.1% on Saturday to 96.1% on Tuesday. With about 52 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why AA 1226 runs late
One category carries most of the weight here. Carrier accounts for 59% of the 2,705 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 59%Carrier
- 23%Late-arriving aircraft
- 16%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 59%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,594 of the 2,705 delay minutes reported here. The split is drawn from 2,705 delay minutes reported on AA 1226.
Cancellations run at 4.14%, against 1.81% 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
Badly late arrivals are rare here: only 3.5% land an hour or more behind schedule, against 8.1% 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
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: 4.14% 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.
