Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Frontier Airlines.
Frontier on CLT to LGA draws a D−. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is close to two hours behind schedule. Build slack into anything you connect to. That rests on 235 flights. The strongest carrier on the route with a full sample, Republic Airways, flew 964 at 81.4% on time.
The national on-time rate over the same period is 77.6%, so Frontier on CLT to LGA runs 16 points behind the country as a whole. Across a thousand flights that is about 158 extra late arrivals.

These figures cover 235 flights between July 2025 and June 2026. Beyond the headline rate, 19.1% 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.
Carrier by carrier
Frontier against every carrier on CLT to LGA
Frontier flew 235 of the 4,332 flights on CLT to LGA, about 5% of it. Its 61.8% on time is 10 points worse than the route as a whole, which runs 72.1%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Republic at 81.4% to Frontier at 61.8%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Republic Airways arrives on time 81.4% of the time; American Airlines manages 68.9%. Sample sizes sit next to every figure, because a two-point gap across 2,802 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Republic Airways | 964 | 81.4% | 81 min | 4.15% | B− |
| Spirit Airlinesthin sample | 331 | 79.2% | 72 min | 3.93% | B− |
| American Airlines | 2,802 | 68.9% | 76 min | 3.78% | C− |
| Frontier Airlines (this page)thin sample | 235 | 61.8% | 102 min | 4.26% | D− |
Republic Airways cancels 4.2% 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.
Departure window
When Frontier runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 24 points, against 13 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am—
- 8am–11am58 flights79.3%
- 11am–2pm11 flights—
- 2pm–5pm39 flights57.9%
- 5pm–8pm122 flights55.3%
- 8pm–5am5 flights—
Scale runs 45% to 85%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 55.3% on time, against 79.3% for the 8am–11am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5pm–8pm window is the busiest, with 122 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 61.8% on time across 235 flights.
Frontier on CLT to LGA did not run the same all year. Its best quarter was Jul–Sep 2025 at 80.9% on time and its weakest Oct–Dec 2025 at 46.6%, a swing of 34 points on roughly 59 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Tuesday is the strongest day at 65.1% on time and Sunday the weakest at 59.5%. 6 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Frontier runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 8,786 reported delay minutes.
- 37%Late-arriving aircraft
- 35%National Airspace System
- 27%Carrier
- 0%Extreme weather
37% 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 8,786 reported delay minutes here, that single category outweighs weather by 37 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. The split is drawn from 8,786 reported delay minutes.
35% 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 3,103 minutes out of 8,786, against a national NAS share of 21%.
Cancellations run at 4.26%, against 1.81% nationally. That is about one flight in 25 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 19.1% of arrivals land a full hour or more behind schedule, against 8.1% 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.
The 544 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg runs 60.1% on time across 235 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 235 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 Frontier on CLT to LGA
Put together: the delay figures matter less here than the 4.26% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 225 completed flights over 12 months sit behind that.
