B+GRADE

United Airlines at Cleveland earns a B+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.4%. When something does go wrong the average delay runs a little over an hour. That rests on 8,816 flights, of which Delta Air Lines flew 3,443 at 87.6% on time.

Measured against the airport rather than the country, United Airlines runs 6 points ahead of the 79.4% weighted average across all carriers at CLE. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#2

Of 12 carriers clearing the floor at CLE

These figures cover 8,816 flights between June 2025 and May 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.

Against the competition

Every carrier at CLE, ranked

The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 87.6% of the time; Alaska Airlines manages 65.1%. Sample sizes sit next to every figure, because a two-point gap across 459 flights means less than a ten-point one.

Route by route

Where United Airlines flies from CLE

United Airlines operates 11 routes out of CLE with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window

Best time of day for this operation

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 31 points, against 23 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am2,654 flights92.7%
  • 8am–11am2,124 flights90.0%
  • 11am–2pm911 flights83.4%
  • 2pm–5pm1,840 flights82.3%
  • 5pm–8pm1,029 flights61.9%
  • 8pm–5am258 flights76.7%

Scale runs 55% to 100%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 61.9% on time, against 92.7% 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.

Darker means more delays. Figures are on-time percentages.February best, December worst

December is the weak month at 78.2% on time, against 89.9% in February. 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.

Delay causes

What holds this operation up

  • National Airspace System
    51%
  • Late-arriving aircraft
    28%
  • Carrier
    18%
  • Extreme weather
    3%

51% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 52,000 minutes out of 101,000, against a national NAS share of 21%.

Cancellations are rare at 0.84%, below the national 1.80% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

5.4% 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 are the a little over an hour kind, which a normal layover absorbs.

The sample behind these figures is 8,816 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.

Put together: avoid the 5pm–8pm departure. It runs 61.9% on time against 92.7% for the 5am–8am slot, and that 31 points is the largest single thing you control here. Delta Air Lines is the strongest operator if the fares are close.

Common questions

United Airlines at CLE

How often is United Airlines at CLE delayed?

About one flight in seven arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 15.1% of the 8,816 flights in this analysis, against 22.6% nationally. Delayed flights are late by a little over an hour on average.

Which airline is most reliable on United Airlines at CLE?

Delta Air Lines leads at 87.6% on time across 3,443 flights. Alaska Airlines is at the other end on 65.1%, a gap of 23 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 United Airlines at CLE?

The 5am–8am departure window is the strongest at 92.7% on time. The 5pm–8pm window is the weakest at 61.9%, 31 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 United Airlines at CLE?

December is the weakest month at 78.2% on time, compared with 89.9% in February. Across the year that is 12 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
