Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Allegiant Air.
Allegiant on FLL to IND draws a D. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 232 flights. The strongest carrier on the route with a full sample, Spirit Airlines, flew 372 at 70.7% on time.
The national on-time rate over the same period is 77.6%, so Allegiant on FLL to IND runs 16 points behind the country as a whole. Across a thousand flights that is about 165 extra late arrivals.

These figures cover 232 flights between July 2025 and June 2026. Beyond the headline rate, 15.7% 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.
Carrier by carrier
Allegiant against every carrier on FLL to IND
Allegiant flew 232 of the 1,047 flights on FLL to IND, about 22% of it. Its 61.1% on time is 5 points worse than the route as a whole, which runs 65.8%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Spirit at 70.7% to Frontier at 57.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Spirit Airlines arrives on time 70.7% of the time; Southwest Airlines manages 64.6%. Sample sizes sit next to every figure, because a two-point gap across 420 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Spirit Airlines | 372 | 70.7% | 86 min | 3.49% | C− |
| Southwest Airlines | 420 | 64.6% | 60 min | 0.95% | D+ |

Spirit Airlines cancels 3.5% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.
Departure window
When Allegiant runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 34 points, against 6 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

- 8am–11am31 flights80.0%
- 11am–2pm30 flights—
- 2pm–5pm46 flights45.7%
- 5pm–8pm94 flights51.6%
- 8pm–5am7 flights—
Scale runs 35% to 85%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 80.0% of the time, against 45.7% for the afternoon window. That is 34 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 94 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 61.1% on time across 232 flights.
Allegiant on FLL to IND did not run the same all year. Its best quarter was Oct–Dec 2025 at 71.2% on time and its weakest Jan–Mar 2026 at 48.3%, a swing of 23 points on roughly 58 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.
Across the week, Thursday is the strongest day at 75.0% on time and Monday the weakest at 51.3%. 24 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Allegiant runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 48% of the 6,880 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.
- 48%Late-arriving aircraft
- 34%National Airspace System
- 10%Carrier
- 8%Extreme weather
48% 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 6,880 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 6,880 reported delay minutes.
34% 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 2,310 minutes out of 6,880, against a national NAS share of 21%.
Cancellations sit at 1.29% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and stage length
What a delay here costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 15.7% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 1,005 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.
The return leg is a different operation and performs like one: it runs 67.4% on time across 232 flights, 6 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 6 points of difference.
One caution: this is a thin sample. 232 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 FLL to IND
Put together: treat all of this as provisional. 232 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 61.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 229 completed flights over 12 months sit behind that.
