These figures cover 257 flights between September 2025 and August 2026. The median arrival is 2 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.

Share of 255 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 50 departures that left 15 minutes late or more, only 5 made it up before arrival. In the other direction, 26 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 FLL.

Delay causes

Why Allegiant runs late on this route

Late-arriving aircraft accounts for 44% of the 4,357 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft

National Airspace System
33%

Extreme weather

44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,357 reported delay minutes here, that single category outweighs weather by 10 to one. The split is drawn from 4,357 reported delay minutes.

33% 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 1,428 minutes out of 4,357, against a national NAS share of 21%.

Cancellations are rare at 0.39%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

6.7% 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 about an hour, which a normal layover absorbs.

The 932 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.

The return leg runs 71.5% on time across 257 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

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 Allegiant on CVG to FLL

Put together: treat all of this as provisional. 257 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 72.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 255 completed flights over 12 months sit behind that.
