This route lands a B+, about a point 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 about an hour on average. That rests on 2,065 CLT to LAS flights, with a median arrival 8 minutes early.
Best time to fly CLT to LAS: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 90.7% of the time and Wednesday flights 86.9%, against 78.3% for the route overall.
The US average over the same twelve months is 77.3%, so there is little to separate this route from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

The 8pm–5am window is where this operation falls apart: 64.3% on time, against 90.7% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5pm–8pm window is the busiest, with 491 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.
July is the worst month at 63.2% on time, 22 points below January, the best at 85.0%. 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. October was the busiest month here, with 194 flights.
Across the week, Wednesday is the strongest day at 86.9% on time and Sunday the weakest at 73.9%, a spread of 13 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 46% of the 28,000 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 30%Carrier
- 19%National Airspace System
- 6%Extreme weather
- 0%Security
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 28,000 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 28,426 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 90.7% on time here.
Cancellations sit at 0.97% against a national 1.89%, which is ordinary. Diversions add another 0.24%.
Connections and stage length
What a delay here actually costs
8.1% 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 about an hour, 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 87.0% on time across 2,066 flights, 9 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 9 points of difference.
The sample behind these figures is 2,065 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. January runs 85.0% on time and July 63.2%, a swing of 22 points. If the dates move at all, move them out of July before you think about anything else. 2,040 completed flights over 12 months sit behind that.
Common questions
CLT to LAS questions
How often is CLT to LAS delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 21.7% of the 2,065 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
How reliable is CLT to LAS compared with the rest of the country?
78.3% of flights arrive on time here against a national 77.3%, a difference of about a point in its favour. That is worth a B+ on this site's grading scale.
What time of day has the fewest delays on CLT to LAS?
The 5am–8am departure window is the strongest at 90.7% on time. The 8pm–5am window is the weakest at 64.3%, 26 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 July delays on CLT to LAS?
July is the weakest month at 63.2% on time, compared with 85.0% in January. 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.
