This route sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.3%. The late ones land about an hour behind schedule. That rests on 1,003 LAS to CLE flights, with a median arrival 3 minutes early.
Best time to fly LAS to CLE: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 94.7% of the time and Wednesday flights 86.5%, against 73.1% for the route overall.
The national on-time rate over the same period is 77.3%, so this route runs 4 points behind the country as a whole. Across a thousand flights that is about 42 extra late arrivals.

These figures cover 1,003 flights between September 2025 and August 2026. The median arrival is 3 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 94.7% of the time, against 51.1% for the afternoon window. That is 44 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 352 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 41 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 44.3% on time, 41 points below September, the best at 85.5%. 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. March was the busiest month here, with 93 flights.
Across the week, Wednesday is the strongest day at 86.5% on time and Friday the weakest at 62.0%, a spread of 25 points.
Delay causes
Why this route gets delayed
Carrier accounts for 45% of the 17,000 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 44%Late-arriving aircraft
- 11%National Airspace System
- 1%Extreme weather
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 17,000 reported delay minutes here, that single category outweighs weather by 44 to one. The split is drawn from 16,888 reported delay minutes.
The largest share of delay minutes, 45%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 7,561 of the 17,000 delay minutes reported here.
Cancellations sit at 1.79% against a national 1.89%, which is ordinary. Diversions add another 0.10%.
Connections and stage length
What a delay here actually costs
7.6% 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 1,824 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 runs 75.7% on time across 1,001 flights, within 3 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 1,003 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 this route
Put together: treat all of this as provisional. 1,003 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 73.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 984 completed flights over 12 months sit behind that.
Common questions
LAS to CLE questions
How often is LAS to CLE delayed?
About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 26.9% of the 1,003 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
How reliable is LAS to CLE compared with the rest of the country?
73.1% of flights arrive on time here against a national 77.3%, a difference of 4 points against it. That is worth a C on this site's grading scale.
What time of day has the fewest delays on LAS to CLE?
The 5am–8am departure window is the strongest at 94.7% on time. The 2pm–5pm window is the weakest at 51.1%, 44 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 LAS to CLE?
July is the weakest month at 44.3% on time, compared with 85.5% in September. Across the year that is 41 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
