These figures cover 259 flights between July 2025 and June 2026. The median arrival is 14 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

When F9 1668 flies

F9 1668 flies CVG to TPA without a single fixed slot. Its most common scheduled departure was 06:00, used on 58 of 259 flights, with 06:05 (41 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and F9 1668 runs 2 points worse at 87.3%. 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 1668 quarter by quarter

F9 1668 did not run the same all year. Its best quarter was Jul–Sep 2025 at 95.4% on time and its weakest Oct–Dec 2025 at 81.2%, a swing of 14 points on roughly 65 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.

Oct–Dec 202548 flights81.2%
Jan–Mar 202662 flights83.9%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, F9 1668 did best on Friday at 93.9% on time and worst on Saturday at 81.8%. Each day rests on about 37 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Delay causes

Why F9 1668 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 53% of the 2,667 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.

Late-arriving aircraft
53%
Carrier
28%
National Airspace System
10%
Extreme weather
9%

53% 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 2,667 reported delay minutes here, that single category outweighs weather by 6 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 2,667 delay minutes reported on F9 1668.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.5% 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 773 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 259 flights under F9 1668 in the data flew CVG 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. 259 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 1668

For a booking, F9 1668 has one of the better records a US domestic flight can show: 87.3% on time and 0.00% cancelled. That is a base rate, not a promise about any single day.
