This route earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.3%. When something does go wrong the average delay runs an hour and a half. That rests on 2,066 LAS to CLT flights, with a median arrival 15 minutes early.
Best time to fly LAS to CLT: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 93.2% of the time and Wednesday flights 94.9%, against 87.0% for the route overall.
Set against the rest of the country, this route's record is 10 points better than the US average of 77.3%. That gap is worth roughly 97 fewer late arrivals for every thousand flights.

These figures cover 2,066 flights between September 2025 and August 2026. The median arrival is 15 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.

Book the early departure. Flights leaving between 5am–8am arrive on time 93.2% of the time, against 75.4% for the afternoon window. That is 18 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 657 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 22 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
August is the worst month at 72.5% on time, 22 points below April, the best at 94.3%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. May was the busiest month here, with 193 flights.
Across the week, Wednesday is the strongest day at 94.9% on time and Sunday the weakest at 81.8%, a spread of 13 points.
Delay causes
Why this route gets delayed
Carrier accounts for 54% of the 26,000 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Carrier
- 39%Late-arriving aircraft
- 6%National Airspace System
- 1%Extreme weather
39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 26,000 reported delay minutes here, that single category outweighs weather by 39 to one. The split is drawn from 26,282 reported delay minutes.
The largest share of delay minutes, 54%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 14,000 of the 26,000 delay minutes reported here.
Cancellations sit at 0.92% against a national 1.89%, which is ordinary. Diversions add another 0.58%.
Connections and stage length
What a delay here actually costs
5.2% 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 1,916 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 78.3% on time across 2,065 flights, 9 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 9 points of difference.
The sample behind these figures is 2,066 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. April runs 94.3% on time and August 72.5%, a swing of 22 points. If the dates move at all, move them out of August before you think about anything else. 2,035 completed flights over 12 months sit behind that.
Common questions
LAS to CLT questions
How often is LAS to CLT delayed?
About one flight in eight arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 13.0% of the 2,066 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
How reliable is LAS to CLT compared with the rest of the country?
87.0% of flights arrive on time here against a national 77.3%, a difference of 10 points in its favour. That is worth a A+ on this site's grading scale.
What time of day has the fewest delays on LAS to CLT?
The 5am–8am departure window is the strongest at 93.2% on time. The 2pm–5pm window is the weakest at 75.4%, 18 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are August delays on LAS to CLT?
August is the weakest month at 72.5% on time, compared with 94.3% in April. Across the year that is 22 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
