Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.
Republic on IAD to CLE lands a B−, 4 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That rests on 280 flights, with a median arrival 8 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on IAD to CLE from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 280 flights between September 2025 and August 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 matters more here than the choice of carrier. The gap between the best and worst window is 11 points, against half a point between the best and worst carrier.

- 8am–11am—
- 11am–2pm69 flights86.8%
- 2pm–5pm—
- 5pm–8pm144 flights76.1%
- 8pm–5am67 flights84.6%
Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 86.8% on time, ahead of 5pm–8pm at 76.1%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 5pm–8pm window is the busiest, with 144 flights scheduled in it.

The worst days
Worst days for Republic on IAD to CLE
The latest arrival of the period was on 12 June 2026, 6 hours 30 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across June, July and December, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 12 June 2026 | 6 hours 30 minutes | Carrier |
| 5 July 2026 | 5 hours 54 minutes | National Airspace System |
| 11 June 2026 | 4 hours 28 minutes | Extreme weather |
| 14 December 2025 | 4 hours 7 minutes | Late-arriving aircraft |

Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 45% of the 3,785 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 26%National Airspace System
- 20%Carrier
- 9%Extreme weather
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,785 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 3,785 reported delay minutes.
Cancellations run at 3.21%, against 1.89% nationally. That is about one flight in 30 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
6.6% of arrivals land an hour or more late, close to the national 8.3%, so 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.
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 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 85.4% on time across 276 flights, 5 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 5 points of difference.
One caution: this is a thin sample. 280 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: the delay figures matter less here than the 3.21% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 271 completed flights over 12 months sit behind that.
