Frontier on CLE to LAS 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 an hour and a half behind schedule. That rests on 634 flights, with a median arrival 5 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Frontier on CLE to LAS from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Across the year
Frontier on CLE to LAS through the year
February is the weak month at 52.8% on time, against 89.4% in September. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. July was the busiest month here, with 62 flights.
Across the week, Saturday is the strongest day at 81.7% on time and Sunday the weakest at 65.1%, a spread of 17 points.

|---|---|---|
| 30 December 2025 | 13 hours 49 minutes | Carrier |

Delay causes
Why Frontier runs late on this route
Late-arriving aircraft accounts for 55% of the 15,000 delay minutes carriers reported here, and the remaining four split what is left.
- 55%Late-arriving aircraft
- 29%Carrier
- 15%National Airspace System
- 2%Extreme weather
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 15,000 reported delay minutes here, that single category outweighs weather by 31 to one. The split is drawn from 14,566 reported delay minutes.
Cancellations run at 2.52%, 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
10.8% 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 1,824 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 72.9% on time across 636 flights, within half a point 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. 634 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 Frontier on CLE to LAS
Put together: treat all of this as provisional. 634 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 73.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 618 completed flights over 12 months sit behind that.
