Departure window
The best time of day to leave CLE in August
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 25 points, against 13 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am911 flights92.1%
- 8am–11am519 flights92.2%
- 11am–2pm511 flights82.2%
- 2pm–5pm744 flights77.1%
- 5pm–8pm652 flights67.0%
- 8pm–5am155 flights67.1%
Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 92.2% of the time, against 67.0% for the evening window. That is 25 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 911 flights scheduled in it.
Across the week, Tuesday is the strongest day at 86.1% on time and Sunday the weakest at 78.4%. 8 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at CLE in August
The choice of carrier is not cosmetic here. United Airlines arrives on time 86.6% of the time; Frontier Airlines manages 74.0%. Sample sizes sit next to every figure, because a two-point gap across 542 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| United Airlines | 759 | 86.6% | 72 min | 1.32% | A |

Delay causes
What held CLE up in August
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 47,000 reported delay minutes.
- 41%Late-arriving aircraft
- 30%Carrier
- 26%National Airspace System
- 3%Extreme weather
- 0%Security
41% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 47,000 reported delay minutes here, that single category outweighs weather by 14 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 47,103 reported delay minutes.
Cancellations sit at 1.80% against a national 1.08%, which is ordinary. Diversions add another 0.34%.
6.5% of arrivals land an hour or more late, close to the national 8.2%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
