Every carrier on LAS to TUL, 744 flights

These figures cover 109 flights between July 2025 and June 2026. The median arrival is 8 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

Allegiant against every carrier on LAS to TUL

Allegiant flew 109 of the 744 flights on LAS to TUL, about 15% of it. Its 84.1% on time is 7 points better than the route as a whole, which runs 76.8%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Allegiant at 84.1% to Southwest at 75.6%.

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 Allegiant 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 109 flights.

There are not enough flights in each departure window to split Allegiant's LAS to TUL record by time of day without the percentages moving on noise. The headline rate of 84.1% is the reliable figure here.

Across the year

Allegiant on LAS to TUL through the year

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 84.1% on time across 109 flights.

Split by quarter, Allegiant on LAS to TUL logged 28 flights in Jul–Sep 2025, 28 flights in Oct–Dec 2025, 27 flights in Jan–Mar 2026 and 26 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 84.1% annual figure is the one to use.

Across the week, Monday is the strongest day at 87.8% on time and Friday the weakest at 80.4%. 7 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. Carrier accounts for 61% of the 1,379 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.

Extreme weather

The largest share of delay minutes, 61%, 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 846 of the 1,379 delay minutes reported here. The split is drawn from 1,379 reported delay minutes.

Cancellations sit at 1.83% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 4.7% 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.

The 1,076 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 75.7% on time across 109 flights, 8 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 8 points of difference.

One caution: this is a thin sample. 109 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 LAS to TUL

Put together: treat all of this as provisional. 109 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 84.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 107 completed flights over 12 months sit behind that.
