CLT to JAX against comparable routes
July 2023 – July 2026| Measure | This route | Compared with | Them | Gap | Flights behind it |
|---|---|---|---|---|---|
| Hour: 12 PM departures | 71.3% | routes of similar length | 81.4% | −10.1 pts | 136 here, 57,638 there |
| Weekday: Saturday | 73.2% | routes of similar length | 82.4% | −9.2 pts | 918 here, 132,386 there |
| Month: July | 54.3% | routes of similar length | 73.4% | −19.1 pts | 672 here, 122,829 there |
| Airline: American Airlines | 73.9% | routes of similar length | 76.7% | −2.8 pts | 6,651 here, 150,921 there |
Each comparison pools the flights of other routes, with this route’s own left out. Similar length means within 15% of this route’s 328 miles, with at least 5 such routes. A bucket is set against the most comparable group that has enough flights: similar length, then the same origin (at least 3 routes), then all other routes. Hours, weekdays and months appear only where both sides have 120 completed flights, and airlines where both have 600. The gap must be at least 2 points and 2 standard errors, and only the largest gap each way is kept per measure. These are differences in the flights counted, not causes.
Why CLT → JAX flights are cancelled
July 2023 – July 2026
CLT → JAX cancelled 95 of 6,764 scheduled flights — about 1 in every 71. The reason filed most often was extreme weather, 83.2% of the cancellations coded on this route — about 1 in every 86 scheduled flights.
Share of cancellations
Of 95 cancelled departures carrying a reason code.
What each reason means
Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.
79 cancellations, 83.2% of the total.
Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.
14 cancellations, 14.7% of the total.
Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
2 cancellations, 2.1% of the total.
A terminal evacuation, a security breach, screening equipment failure, or screening queues over 29 minutes.
0 cancellations, 0.0% of the total.
Reason codes are the operating airline’s own filing with US DOT, not an independent finding of fault. With only one or two carriers on the route, the split mostly reflects how they file. Ordinary bad weather is filed under air traffic, so weather’s full share is larger than its bar.
95 coded cancellations were recorded on CLT → JAX; the section appears from 50.

Will your connection be tight enough?
Layovers at JAX after arriving from CLT.
| Connection time | Chance of missing | Reads as |
|---|---|---|
| 30 min | 43% | Likely to miss |
| 45 min | 25% | High risk |
| 60 min | 17% | High risk |
| 90 min | 9.2% | Some risk |
| 120 min | 5.9% | Some risk |
This is one leg of a connection. Gate changes and the next flight's own schedule matter too. And a connection can fail before delay is even the question — this route cancels 1.40% of the time and diverts 0.13% of the time, which a late arrival never shows up in.
Chance of missing is the share of 6,660 arrivals on this route that landed later than the connection time less 30 minutes to reach the next gate.
The worst tenth of arrivals on this route land at least 57 minutes late (90th-percentile gate arrival delay), over 6,764 operations.

Why CLT → JAX runs late
July 2023 – July 2026
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
screening or terminal security incidents
Share of the delay minutes US DOT attributed to each cause for CLT → JAX. Only delays of 15 minutes or more are attributed. What the five causes mean
Late-arriving aircraft is the largest cause on CLT → JAX, at 57.7%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 88.0% of the time and 9 PM–5 AM departures 64.2%.
