Every carrier on IAD to CLE, 985 flights

These figures cover 274 flights between July 2025 and June 2026. The median arrival is 8 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.

Departure window

When Republic runs best on this route

Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 274 flights.

8am–11am—
11am–2pm88 flights86.2%
2pm–5pm—
5pm–8pm110 flights81.3%
8pm–5am76 flights86.5%

Scale runs 75% to 90%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is the strongest at 86.5% on time. The full set of windows spans 5 points.

Quarter by quarter Republic on IAD to CLE held fairly steady: 84.8% in Jul–Sep 2025, 81.4% in Oct–Dec 2025, 88.5% in Jan–Mar 2026 and 84.0% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Across the week, Monday is the strongest day at 92.1% on time and Sunday the weakest at 72.1%. 20 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Republic runs late on this route

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 3,156 reported delay minutes.

Late-arriving aircraft
41%
Carrier
31%
National Airspace System
18%
Extreme weather
10%

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 3,156 reported delay minutes here, that single category outweighs weather by 4 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 3,156 reported delay minutes.

Cancellations sit at 2.19% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

Badly late arrivals are rare here: only 4.9% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

At 287 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 8pm–5am window matters as much as it does.

The return leg runs 86.3% on time across 269 flights, within 2 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. 274 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 Republic on IAD to CLE

Put together: treat all of this as provisional. 274 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 84.3% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 268 completed flights over 12 months sit behind that.
