Why CLT → ATL flights are cancelled

July 2023 – July 2026

CLT → ATL cancelled 209 of 15,216 scheduled flights — about 1 in every 73. The reason filed most often was extreme weather, 63.6% of the cancellations coded on this route — about 1 in every 114 scheduled flights.

What each reason means

Extreme weather1 in 114

Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.

133 cancellations, 63.6% of the total.

The airline1 in 227

Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.

67 cancellations, 32.1% of the total.

The air traffic system1 in 1,691

Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.

9 cancellations, 4.3% of the total.

Security—

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. Ordinary bad weather is filed under air traffic, so weather’s full share is larger than its bar.

209 coded cancellations were recorded on CLT → ATL; the section appears from 50.

Will your connection be tight enough?

Layovers at ATL after arriving from CLT.

Connection buffer and chance of missing by layover length, CLT → ATL arrivals
Connection time	Chance of missing	Reads as
30 min	33%	Likely to miss
45 min	19%	High risk
60 min	13%	Some risk
90 min	7.3%	Some risk
120 min	4.6%	Low 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 1.37% of the time and diverts 0.11% of the time, which a late arrival never shows up in.

Chance of missing is the share of 14,991 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 43 minutes late (90th-percentile gate arrival delay), over 15,216 operations.
