F9 3216 earns a D, which is as low as this site's scale goes for a reason. Only 57.9% of flights arrive inside the 15-minute window, 20 points worse than the national rate of 77.6%. Late arrivals average about an hour. Treat any tight connection here as a coin flip. That rests on 257 flights, with a median arrival 9 minutes late.
The national on-time rate over the same period is 77.6%, so F9 3216 runs 20 points behind the country as a whole. Across a thousand flights that is about 197 extra late arrivals.

These figures cover 257 flights between July 2025 and June 2026. Beyond the headline rate, 13.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Across the year
F9 3216 quarter by quarter
F9 3216 did not run the same all year. Its best quarter was Apr–Jun 2026 at 78.3% on time and its weakest Jul–Sep 2025 at 43.8%, a swing of 35 points on roughly 64 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 3216 did best on Thursday at 72.5% on time and worst on Sunday at 50.0%. Each day rests on about 37 flights, so a gap of 23 points is worth noticing but could still narrow in another year.
Delay causes
Why F9 3216 runs late
One category carries most of the weight here. Carrier accounts for 45% of the 6,977 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.
- 45%Carrier
- 43%Late-arriving aircraft
- 12%National Airspace System
- 0%Extreme weather
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 6,977 reported delay minutes here, that single category outweighs weather by 43 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 6,977 delay minutes reported on F9 3216.
Cancellations sit at 1.95% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 13.9% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
At 1,947 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
Every one of the 257 flights under F9 3216 in the data flew LAX 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. 257 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 3216
For a booking, F9 3216 is a flight to put a long connection behind. 13.9% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
