These figures cover 195 flights between September 2025 and August 2026. The median arrival is 9 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 BNA

Spirit flew 195 of the 2,060 flights on LAS to BNA, about 9% of it. Its 84.1% on time is 7 points better than the route as a whole, which runs 77.3%. Ranked by on-time rate it is number two of six carriers on the route, where the range runs from American at 100.0% to Delta at 50.0%. Four 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.

Book the morning departure. Flights leaving between 8am–11am arrive on time 95.9% of the time, against 73.8% for the overnight window. That is 22 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 89 flights scheduled in it.

Share of 189 completed flights by arrival against schedule.

3 of 23 late departures made up the time and arrived on time, 13% of them. In the other direction, 10 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at BNA.

Delay causes

Why Spirit runs late on this route

Carrier accounts for 66% of the 2,569 delay minutes carriers reported here, and the remaining four split what is left.

National Airspace System

The largest share of delay minutes, 66%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,695 of the 2,569 delay minutes reported here. The split is drawn from 2,569 reported delay minutes.

Cancellations run at 3.08%, against 1.89% nationally. That is roughly one flight in 30 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

6.9% of arrivals land an hour or more late, close to the national 8.3%, so 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 1,587 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 79.8% on time across 198 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. 195 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 BNA

Put together: the delay figures matter less here than the 3.08% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 189 completed flights over 12 months sit behind that.
