These figures cover 315 flights between September 2025 and August 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.

Across the year

Share of 307 completed flights by arrival against schedule.
A late pushback is often recovered here: of 36 departures that left 15 minutes late or more, 15 still arrived on time. In the other direction, 36 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ATL.

Delay causes
Why F9 2483 runs late
National Airspace System accounts for 47% of the 2,415 delay minutes carriers reported here, and the remaining four split what is left.
- 47%National Airspace System
- 31%Late-arriving aircraft
- 19%Carrier
- 2%Extreme weather
47% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,136 minutes out of 2,415, against a national NAS share of 21%. The split is drawn from 2,415 delay minutes reported on F9 2483.
Cancellations run at 2.54%, against 1.89% nationally. That is about one flight in 40 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 2.6% 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 594 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 315 flights under F9 2483 in the data flew MIA to ATL. 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. 315 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 F9 2483
For a booking, the cancellation rate is the figure to plan around on F9 2483: 2.54% of its 315 scheduled flights did not operate. A late arrival costs roughly 40 minutes, but a cancellation costs the day, so leave a later option open.
