F9 2483 lands a B, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by roughly 45 minutes on average.

These figures cover 305 flights between July 2025 and June 2026. The median arrival is 10 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

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 05:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and F9 2483 runs 6 points worse at 83.2%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
F9 2483 quarter by quarter
F9 2483 did not run the same all year. Its best quarter was Oct–Dec 2025 at 87.3% on time and its weakest Apr–Jun 2026 at 75.6%, a swing of 12 points on roughly 76 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, F9 2483 did best on Thursday at 90.0% on time and worst on Tuesday at 71.0%. Each day rests on about 44 flights, so a gap of 19 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 2483 runs late
One category carries most of the weight here. National Airspace System accounts for 47% of the 2,134 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.
- 47%National Airspace System
- 30%Late-arriving aircraft
- 23%Carrier
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 1,010 minutes out of 2,134, against a national NAS share of 21%. The split is drawn from 2,134 delay minutes reported on F9 2483.
Cancellations sit at 2.30% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
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 8.1% 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 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. 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 305 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. 305 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.
