Carrier by carrier
Frontier against every carrier on CLT to LGA
Frontier flew 242 of the 4,193 flights on CLT to LGA, about 6% of it. Its 51.6% on time is 20 points worse than the route as a whole, which runs 71.5%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Republic at 79.8% to Frontier at 51.6%. 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 79.8% of the time; American Airlines manages 69.8%. Sample sizes sit next to every figure, because a two-point gap across 2,767 flights means less than a ten-point one.

Republic Airways cancels 4.9% 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.

Share of 219 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 99 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 14 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at LGA.
The worst days
Worst days for Frontier on CLT to LGA
The latest arrival of the period was on 22 October 2025, 19 hours 57 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 22 October 2025 | 19 hours 57 minutes | Carrier |
| 15 August 2026 | 17 hours 16 minutes | Carrier |
| 17 August 2026 | 15 hours 40 minutes | Late-arriving aircraft |

Delay causes
Why Frontier runs late on this route
Late-arriving aircraft accounts for 42% of the 12,000 delay minutes carriers reported here, and the remaining four split what is left.
- 42%Late-arriving aircraft
- 33%National Airspace System
- 24%Carrier
- 0%Extreme weather
42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 12,000 reported delay minutes here, that single category outweighs weather by 42 to one. The split is drawn from 12,011 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 3,985 minutes out of 12,000, against a national NAS share of 21%.
Cancellations run at 9.09%, against 1.89% nationally. That is roughly one flight in twelve 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
26.9% 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 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.
The return leg is a different operation and performs like one: it runs 58.5% on time across 242 flights, 7 points above 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 7 points of difference.
One caution: this is a thin sample. 242 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 9.09% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 2pm–5pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 219 completed flights over 12 months sit behind that.
