Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Frontier Airlines.
Frontier on LGA to CLT draws a D. Roughly one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour 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 965 at 81.2% on time.
The national on-time rate over the same period is 77.6%, so Frontier on LGA to CLT runs 17 points behind the country as a whole. Across a thousand flights that is about 175 extra late arrivals.

These figures cover 235 flights between July 2025 and June 2026. Beyond the headline rate, 18.4% 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 LGA to CLT
Frontier flew 235 of the 4,336 flights on LGA to CLT, about 5% of it. Its 60.1% on time is 17 points worse than the route as a whole, which runs 77.2%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Republic at 81.2% to Frontier at 60.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: 3 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |

| American Airlines | 2,804 | 78.0% | 107 min | 3.82% | B− |

Republic Airways cancels 3.9% 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 26 points, against 3 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am—
- 8am–11am—
- 11am–2pm99 flights65.3%
- 2pm–5pm36 flights39.4%
- 5pm–8pm100 flights61.9%
- 8pm–5am—
Scale runs 30% to 70%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 65.3% on time, ahead of 2pm–5pm at 39.4%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 5pm–8pm window is the busiest, with 100 flights scheduled in it.

- Oct–Dec 202562 flights55.9%

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 60.1% on time across 235 flights.
Frontier on LGA to CLT did not run the same all year. Its best quarter was Jul–Sep 2025 at 66.2% on time and its weakest Apr–Jun 2026 at 55.2%, a swing of 11 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 66.7% on time and Saturday the weakest at 61.3%. 5 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Frontier runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 53% of the 6,805 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 53%Late-arriving aircraft
- 27%National Airspace System
- 20%Carrier
53% 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 6,805 reported delay minutes here, that single category outweighs weather by 53 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 6,805 reported delay minutes.
Cancellations run at 2.98%, against 1.81% nationally. That is roughly one flight in 30 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. 18.4% 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 61.8% 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 LGA to CLT
Put together: the delay figures matter less here than the 2.98% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 228 completed flights over 12 months sit behind that.
