Cleveland
Cleveland Hopkins International lands a B, 2 points better than the national rate of 77.6%. About one flight in five arrive 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 40,344 flights, of which Delta Air Lines flew 3,464 at 87.9% on time.
Delta Air Lines is the most reliable of the eleven carriers covered here at 87.9% on time across 3,464 flights.

87.9% on time here
These figures cover 40,000 flights between July 2025 and June 2026. The median arrival is 9 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.
Carrier by carrier
Which airlines run best out of CLE
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 87.9% of the time; Alaska Airlines manages 63.1%. Sample sizes sit next to every figure, because a two-point gap across 456 flights means less than a ten-point one.

PSA Airlines cancels 8.0% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Departure window
The best time of day to leave CLE
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against 25 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am10,525 flights89.1%
- 8am–11am6,357 flights86.6%
- 11am–2pm6,219 flights80.3%
- 2pm–5pm7,903 flights75.9%
- 5pm–8pm7,147 flights67.2%
- 8pm–5am2,193 flights65.2%
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 89.1% of the time, against 65.2% for the overnight window. That is 24 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 10,525 flights scheduled in it.
Across the year
When CLE runs late
CLE's year swings by 15 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.
December is the weak month at 71.2% on time, against 85.8% 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. May was the busiest month here, with 3,745 flights.
Across the week, Wednesday is the strongest day at 83.2% on time and Sunday the weakest at 75.1%. 8 points is a smaller lever than departure hour, but it is free.
Delay causes
Why CLE gets delayed
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 651,000 reported delay minutes.
- 38%Late-arriving aircraft
- 31%Carrier
- 27%National Airspace System
- 4%Extreme weather
- 0%Security
38% 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 651,000 reported delay minutes here, that single category outweighs weather by 9 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 651,434 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 89.1% on time here.
Cancellations sit at 2.26% against a national 1.81%, which is ordinary. Diversions add another 0.25%.
7.9% of arrivals land an hour or more late, close to the national 8.1%. 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 are the a little over an hour kind, which a normal layover absorbs.
40,344 flights sit behind these numbers, which is a large enough sample that the headline rate is not moving on noise. Where a sub-group falls below 30 flights the site shows a dash instead of a percentage.
What to do with this
Flying out of CLE
Put together: the calendar is the biggest lever here, not the carrier or the hour. September runs 85.8% on time and December 71.2%, a swing of 15 points. If the dates move at all, move them out of December before you think about anything else. 39,335 completed flights over 12 months sit behind that.
Common questions
CLE delay questions
How often is Cleveland (CLE) delayed?
About one flight in five arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 20.4% of the 40,344 flights in this analysis, against 22.4% nationally. Delayed flights are late by a little over an hour on average.
Which airline is most reliable on Cleveland (CLE)?
Delta Air Lines leads at 87.9% on time across 3,464 flights. Alaska Airlines is at the other end on 63.1%, a gap of 25 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on Cleveland (CLE)?
The 5am–8am departure window is the strongest at 89.1% on time. The 8pm–5am window is the weakest at 65.2%, 24 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 December delays on Cleveland (CLE)?
December is the weakest month at 71.2% on time, compared with 85.8% in September. Across the year that is 15 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
