Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.

Republic on LGA to CMH carries a cancellation problem, not just a delay problem: 5.4% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, close to three flights in four arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 2,905 flights, with a median arrival 10 minutes early.

The US average over the same twelve months is 77.3%, so there is little to separate Republic on LGA to CMH from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier

Republic against every carrier on LGA to CMH

Republic flew 2,905 of the 3,034 flights on LGA to CMH, most of the route. Its 76.4% on time is about level with the route as a whole at 76.7%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from Delta at 100.0% to Republic at 76.4%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

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 22 points, against half a point between the best and worst carrier.

5am–8am322 flights89.0%
8am–11am531 flights79.2%
11am–2pm493 flights79.5%
2pm–5pm456 flights75.6%
5pm–8pm704 flights71.3%
8pm–5am399 flights67.5%

Scale runs 60% to 95%.

Book the early departure. Flights leaving between 5am–8am arrive on time 89.0% of the time, against 67.5% for the overnight window. That is 22 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 704 flights scheduled in it.

Across the year

Share of 2,744 completed flights by arrival against schedule.

82 of 571 late departures made up the time and arrived on time, 14% of them. In the other direction, 159 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at CMH.

Delay causes

Why Republic runs late on this route

Late-arriving aircraft accounts for 45% of the 53,000 delay minutes carriers reported here, and the remaining four split what is left.

45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 53,000 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 53,438 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 89.0% on time here.

Cancellations run at 5.40%, against 1.89% nationally. That is about one flight in twenty 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

10.8% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

At 479 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 5am–8am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 79.6% on time across 2,904 flights, 3 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 3 points of difference.

The sample behind these figures is 2,905 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.

What to do with this

Booking Republic on LGA to CMH

Put together: the delay figures matter less here than the 5.40% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 2,744 completed flights over 12 months sit behind that.
