These figures cover 293 flights between September 2025 and August 2026. The median arrival is 13 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
F9 3679 quarter by quarter
F9 3679 did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.1% on time and its weakest Jan–Mar 2026 at 71.4%, a swing of 19 points on roughly 73 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.

Delay causes
Why F9 3679 runs late
Late-arriving aircraft accounts for 43% of the 3,718 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Late-arriving aircraft
- 37%Carrier
- 18%National Airspace System
- 2%Extreme weather
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,718 reported delay minutes here, that single category outweighs weather by 19 to one. The split is drawn from 3,718 delay minutes reported on F9 3679.
Cancellations run at 3.07%, against 1.89% nationally. That is roughly one flight in 30 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
5.3% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.
The 927 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 293 flights under F9 3679 in the data flew CLE to TPA. 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. 293 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 3679
For a booking, the cancellation rate is the figure to plan around on F9 3679: 3.07% of its 293 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
