Every carrier on MSY to LAS, 839 flights

These figures cover 101 flights between July 2025 and June 2026. The median arrival is 13 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 MSY to LAS

Spirit flew 101 of the 839 flights on MSY to LAS, about 12% of it. Its 84.0% on time is 5 points better than the route as a whole, which runs 79.3%. Ranked by on-time rate it is first of three carriers on the route, where the range runs from Spirit at 84.0% to Frontier at 52.4%. 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 101 flights.

There are not enough flights in each departure window to split Spirit's MSY to LAS record by time of day without the percentages moving on noise. The headline rate of 84.0% is the reliable figure here.

Across the year

Spirit on MSY to LAS through the year

Jul–Sep 202559 flights79.7%
Oct–Dec 202542 flights90.2%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 84.0% on time across 101 flights.

Split by quarter, Spirit on MSY to LAS logged 59 flights in Jul–Sep 2025 and 42 flights in Oct–Dec 2025. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 84.0% annual figure is the one to use.

Delay causes

Why Spirit runs late on this route

One category carries most of the weight here. Carrier accounts for 73% of the 1,506 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 1,103 of the 1,506 delay minutes reported here. The split is drawn from 1,506 reported delay minutes.

Cancellations sit at 0.99% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

5.0% 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 last an hour and a half, which a normal layover absorbs.

At 1,500 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.

One caution: this is a thin sample. 101 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 MSY to LAS

Put together: treat all of this as provisional. 101 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 84.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 100 completed flights over 12 months sit behind that.
