Every carrier on LAS to TPA, 1,036 flights

These figures cover 232 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.

Carrier by carrier

Spirit against every carrier on LAS to TPA

Spirit flew 232 of the 1,036 flights on LAS to TPA, about 22% of it. Its 84.8% on time is 16 points better than the route as a whole, which runs 68.6%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Spirit at 84.8% to Frontier at 62.6%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

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.

Departure window

When Spirit runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 232 flights.

The 8am–11am window is the strongest at 86.2% on time. The full set of windows spans 2 points.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 84.8% on time across 232 flights.

Split by quarter, Spirit on LAS to TPA logged 121 flights in Jul–Sep 2025, 104 flights in Oct–Dec 2025 and 7 flights in Jan–Mar 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 84.8% annual figure is the one to use.

Across the week, Saturday is the strongest day at 89.2% on time and Sunday the weakest at 76.5%. 13 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Spirit runs late on this route

One category carries most of the weight here. Carrier accounts for 73% of the 2,947 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.

The largest share of delay minutes, 73%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,138 of the 2,947 delay minutes reported here. The split is drawn from 2,947 reported delay minutes.

Cancellations are rare at 0.86%, 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.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 4.8% 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.

At 1,984 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The return leg is a different operation and performs like one: it runs 80.8% on time across 230 flights, 4 points below 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 4 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 Spirit on LAS to TPA

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 84.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 230 completed flights over 12 months sit behind that.
