Allegiant Air at St. Petersburg lands a B+, about a point worse than the national rate of 77.4%. About 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 9,137 flights, with a median arrival 5 minutes early.
Measured against the airport rather than the country, Allegiant Air runs half a point ahead of the 76.0% 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.

#1
Of 1 carriers clearing the floor at PIE
These figures cover 9,137 flights between June 2025 and May 2026. Beyond the headline rate, 8.4% 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.
Against the competition
Every carrier at PIE, ranked
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

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 37 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–8am1,917 flights93.4%
- 8am–11am1,306 flights89.5%
- 11am–2pm1,974 flights71.8%
- 2pm–5pm1,613 flights74.3%
- 5pm–8pm1,685 flights56.0%
- 8pm–5am642 flights65.9%
Scale runs 50% to 100%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 56.0% on time, against 93.4% 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.
Across the year
Seasonal pattern
June is the worst month at 65.3% on time, 18 points below September, the best at 83.4%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck.

- 0%Security
Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.0 times the usual weather exposure.
Cancellations are rare at 0.59%, below the national 1.80% 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.
8.4% of arrivals land an hour or more late, close to the national 8.2%. 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 9,137 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 June 65.3%, a swing of 18 points. If the dates move at all, move them out of June before you think about anything else.
Common questions
Allegiant Air at PIE
How often is Allegiant Air at PIE delayed?
About 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 24.0% of the 9,137 flights in this analysis, against 22.6% 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?
76.0% of flights arrive on time here against a national 77.4%, a difference of about 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 93.4% on time. The 5pm–8pm window is the weakest at 56.0%, 37 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 June delays on Allegiant Air at PIE?
June is the weakest month at 65.3% on time, compared with 83.4% in September. Across the year that is 18 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
