What the record says about this route
The two directions do not behave alike. AUS to MIA arrives on time 8.4 points more often than the outbound. Delay accumulates through the flying day, so whichever direction is scheduled later tends to carry the worse record — which is an argument for booking the morning departure if the choice exists.
Only American Airlines flies this route in the published record, so there is no choice to weigh — the route's figures and the airline's are the same figures.
Flights from Miami to Austin run late more often than the average route, though not severely.
This is a thin route — 200 flights across the whole period. On a route this infrequent a cancellation is far more costly than the rate suggests, because the next departure may not be the same day.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on MIA to AUS during March 2025 – August 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.
A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.
Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
