Allegiant Air at St. Pete-Clearwater International

Departures: 9,084
Period: July 2025 to June 2026
Routes: 25
Rank here: #1 of 1

Allegiant Air at St. Petersburg lands a B+, level with the national rate of 77.6%. Roughly one flight in four arrive 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 9,084 flights, with a median arrival 6 minutes early.

Measured against the airport rather than the country, Allegiant Air runs half a point ahead of the 77.1% weighted average across all carriers at PIE. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

Of 1 carriers clearing the floor at PIE

These figures cover 9,084 flights between July 2025 and June 2026. The median arrival is 6 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.

Route by route

Where Allegiant Air flies from PIE

Allegiant Air operates 25 routes out of PIE with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window

Best time of day for this operation

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 34 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am1,874 flights93.2%
8am–11am1,401 flights89.3%
11am–2pm1,883 flights72.9%
2pm–5pm1,696 flights74.0%
5pm–8pm1,628 flights59.6%
8pm–5am602 flights67.8%

Scale runs 50% to 100%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 59.6% on time, against 93.2% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 11am–2pm window is the busiest, with 1,883 flights scheduled in it.

Across the year

Seasonal pattern

Darker means more delays. Figures are on-time percentages.September best, December worst

December is the weak month at 68.9% on time, against 83.4% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. July was the busiest month here, with 1,003 flights.

44% 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 136,000 reported delay minutes here, that single category outweighs weather by 5 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 136,160 reported delay minutes.

Cancellations are rare at 0.63%, below the national 1.81% 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.

7.7% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route are the about an hour kind, which a normal layover absorbs.

The sample behind these figures is 9,084 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 83.4% on time and December 68.9%, a swing of 15 points. If the dates move at all, move them out of December before you think about anything else. 8,994 completed flights over 12 months sit behind that.

Common questions

Allegiant Air at PIE

How often is Allegiant Air at PIE delayed?

Roughly one flight in four arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 22.9% of the 9,084 flights in this analysis, against 22.4% nationally. Delayed flights are late by about an hour on average.

How reliable is Allegiant Air at PIE compared with the rest of the country?

77.1% of flights arrive on time here against a national 77.6%, a difference of half a point against it. That is worth a B+ on this site's grading scale.

What time of day has the fewest delays on Allegiant Air at PIE?

The 5am–8am departure window is the strongest at 93.2% on time. The 5pm–8pm window is the weakest at 59.6%, 34 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.

How bad are December delays on Allegiant Air at PIE?

December is the weakest month at 68.9% on time, compared with 83.4% in September. Across the year that is 15 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
