These figures cover 159 flights between July 2025 and June 2026. Beyond the headline rate, 8.3% 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.

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 159 flights.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 87.9% on time across 159 flights.

Split by quarter, Spirit on OAK to LAS logged 155 flights in Jul–Sep 2025 and 4 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 87.9% annual figure is the one to use.

Delay causes

Why Spirit runs late on this route

One category carries most of the weight here. National Airspace System accounts for 48% of the 1,997 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.

National Airspace System
48%
Late-arriving aircraft
26%
Carrier

48% 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 956 minutes out of 1,997, against a national NAS share of 21%. The split is drawn from 1,997 reported delay minutes.

Cancellations sit at 1.26% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

8.3% 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 close to two hours, which a normal layover absorbs.

At 407 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 8am–11am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 76.9% on time across 158 flights, 11 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 11 points of difference.

One caution: this is a thin sample. 159 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 OAK to LAS

Put together: treat all of this as provisional. 159 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 87.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 157 completed flights over 12 months sit behind that.
