Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.
Republic on CMH to LGA carries a cancellation problem, not just a delay problem: 5.0% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about four flights in five 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 2,904 flights, with a median arrival 9 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate Republic on CMH to LGA 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 CMH to LGA
Republic flew 2,904 of the 3,035 flights on CMH to LGA, most of the route. Its 79.6% on time is about level with the route as a whole at 79.2%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Delta at 100.0% to Spirit at 70.2%. 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.

Book the early departure. Flights leaving between 5am–8am arrive on time 90.8% of the time, against 70.9% for the evening window. That is 20 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 673 flights scheduled in it.

The worst days
Worst days for Republic on CMH to LGA
The latest arrival of the period was on 30 January 2026, 12 hours 52 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 30 January 2026 | 12 hours 52 minutes | Carrier |
| 17 September 2025 | 11 hours 36 minutes | Carrier |

Delay causes
Why Republic runs late on this route
National Airspace System accounts for 47% of the 41,000 delay minutes carriers reported here, and the remaining four split what is left.
- 47%National Airspace System
- 27%Late-arriving aircraft
- 24%Carrier
- 2%Extreme weather
- 0%Security
47% 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 19,000 minutes out of 41,000, against a national NAS share of 21%. The split is drawn from 40,967 reported delay minutes.
Cancellations run at 4.96%, 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
8.7% 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 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 76.4% on time across 2,905 flights, 3 points below 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 2,904 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 CMH to LGA
Put together: the delay figures matter less here than the 4.96% cancellation rate. A late arrival costs you a little over an hour; 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. 2,748 completed flights over 12 months sit behind that.
