What the record says about this route
The season swings this route hard. In November it ran 23.5 points more punctual than in July — a difference bigger than the one between the best and worst airlines on most routes. If the date is flexible, it is worth more than the carrier.
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.
This is a thin route — 287 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.
The Sacramento to Miami route sits close to the middle of the record — neither notably punctual nor notably late.
Which airline should you fly on this route?
Over July 2024 – July 2026, American Airlines arrived on time most often on SMF to MIA. Flights ran closest to schedule in February and worst in August.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on SMF to MIA during July 2024 – July 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 →
