Why JAX → CLT flights are cancelled
July 2023 – July 2026
JAX → CLT cancelled 97 of 6,766 scheduled flights — about 1 in every 70. The reason filed most often was extreme weather, 81.4% of the cancellations coded on this route — about 1 in every 86 scheduled flights.
Share of cancellations
Of 97 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, 81.4% of the total.
Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.
16 cancellations, 16.5% 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.
97 coded cancellations were recorded on JAX → CLT; the section appears from 50.

Will your connection be tight enough?
Layovers at CLT after arriving from JAX.
| Connection time | Chance of missing | Reads as |
|---|---|---|
| 30 min | 36% | Likely to miss |
| 45 min | 20% | High risk |
| 60 min | 14% | Some risk |
| 90 min | 7.6% | Some risk |
| 120 min | 5.0% | 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 1.43% of the time and diverts 0.16% of the time, which a late arrival never shows up in.
Chance of missing is the share of 6,658 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 44 minutes late (90th-percentile gate arrival delay), over 6,766 operations.

Why JAX → CLT 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 JAX → CLT. Only delays of 15 minutes or more are attributed.
Late-arriving aircraft is the largest cause on JAX → CLT, at 56.5%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 89.5% of the time and 6–9 PM departures 66.3%.
