Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Spirit Airlines.

Spirit on BNA to LAS lands a B, 3 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That rests on 198 flights, with a median arrival 8 minutes early.

The US average over the same twelve months is 77.3%, so there is little to separate Spirit on BNA to LAS from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

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 matters more here than the choice of carrier. The gap between the best and worst window is 18 points, against half a point between the best and worst carrier.

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 2pm–5pm slot at 92.5% on time, ahead of 8pm–5am at 74.6%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 8pm–5am window is the busiest, with 131 flights scheduled in it.

Delay causes

Why Spirit runs late on this route

Carrier accounts for 44% of the 3,656 delay minutes carriers reported here, and the remaining four split what is left.

  • Carrier
    44%
  • Late-arriving aircraft
    33%
  • National Airspace System
    20%
  • Extreme weather
    2%

The largest share of delay minutes, 44%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,617 of the 3,656 delay minutes reported here. The split is drawn from 3,656 reported delay minutes.

Cancellations run at 2.53%, against 1.89% nationally. That is about one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and stage length

What a delay here costs

10.4% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

At 1,587 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 84.1% on time across 195 flights, 4 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 4 points of difference.

One caution: this is a thin sample. 198 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 BNA to LAS

Put together: treat all of this as provisional. 198 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 79.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 193 completed flights over 12 months sit behind that.
