Republic Airways at New York carries a cancellation problem, not just a delay problem: 5.6% of scheduled flights never operate, against 1.8% nationally. Of the ones that do fly, close to three flights in four arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 56,419 flights, of which Republic Airways flew 56,419 at 74.4% on time.
Measured against the airport rather than the country, Republic Airways runs 2 points ahead of the 72.6% weighted average across all carriers at LGA. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#1
Of 9 carriers clearing the floor at LGA
These figures cover 56,000 flights between June 2025 and May 2026. Beyond the headline rate, 10.3% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Against the competition
Every carrier at LGA, ranked
The choice of carrier is not cosmetic here. Republic Airways arrives on time 74.4% of the time; Frontier Airlines manages 60.6%. Sample sizes sit next to every figure, because a two-point gap across 2,409 flights means less than a ten-point one.

Spirit Airlines cancels 6.0% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.
Route by route
Where Republic Airways flies from LGA
Republic Airways operates 25 routes out of LGA with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against 14 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am3,682 flights88.8%
- 8am–11am13,023 flights83.1%
- 11am–2pm9,890 flights78.8%
- 2pm–5pm11,995 flights69.4%
- 5pm–8pm9,589 flights65.0%
- 8pm–5am8,240 flights65.9%
Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 88.8% of the time, against 65.0% for the evening window. That is 24 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on.
Across the year
Seasonal pattern
December is the weak month at 63.8% on time, against 85.9% in August. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days.
Delay causes
What holds this operation up
- 45%Late-arriving aircraft
- 29%National Airspace System
- 21%Carrier
- 4%Extreme weather
- 0%Security
45% 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 937,000 reported delay minutes here, that single category outweighs weather by 10 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.
Cancellations run at 5.62%, against 1.80% nationally. That is roughly 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.
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.3% of arrivals land a full hour or more behind schedule, against 8.2% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
56,419 flights sit behind these numbers, which is a large enough sample that the headline rate is not moving on noise. Where a sub-group falls below 30 flights the site shows a dash instead of a percentage.
Put together: the delay figures matter less here than the 5.62% 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.
Common questions
Republic Airways at LGA
How often is Republic Airways at LGA delayed?
About one flight in four arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 25.6% of the 56,419 flights in this analysis, against 22.6% nationally. Delayed flights are late by a little over an hour on average.
Which airline is most reliable on Republic Airways at LGA?
Republic Airways leads at 74.4% on time across 56,419 flights. Frontier Airlines is at the other end on 60.6%, a gap of 14 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on Republic Airways at LGA?
The 5am–8am departure window is the strongest at 88.8% on time. The 5pm–8pm window is the weakest at 65.0%, 24 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are December delays on Republic Airways at LGA?
December is the weakest month at 63.8% on time, compared with 85.9% in August. Across the year that is 22 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
