Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Republic Airways.
Republic on ATL to LGA carries a cancellation problem, not just a delay problem: 5.9% 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 1,905 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 4,937 at 75.9% on time.
Delta Air Lines is the most reliable of the three carriers covered here at 75.9% on time across 4,937 flights.

Carrier by carrier
Republic against every carrier on ATL to LGA
Republic flew 1,905 of the 8,502 flights on ATL to LGA, about 22% of it. Its 75.5% on time is 3 points better than the route as a whole, which runs 72.3%. Ranked by on-time rate it is number two of six carriers on the route, where the range runs from Delta at 75.9% to Frontier at 46.2%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 75.9% of the time; Frontier Airlines manages 46.2%. Sample sizes sit next to every figure, because a two-point gap across 950 flights means less than a ten-point one.

Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 47% of the 38,000 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 33%National Airspace System
- 12%Carrier
- 8%Extreme weather
- 0%Security
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 38,000 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 38,390 reported delay minutes.
33% 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 13,000 minutes out of 38,000, against a national NAS share of 21%.
Cancellations run at 5.88%, against 1.89% nationally. That is roughly one flight in fifteen 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
11.8% 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.
The 762 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg runs 76.4% on time across 1,906 flights, within about a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
The sample behind these figures is 1,905 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 ATL to LGA
Put together: the delay figures matter less here than the 5.88% 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. 1,786 completed flights over 12 months sit behind that.
