Why ATL → CLT flights are cancelled

July 2023 – July 2026

ATL → CLT cancelled 215 of 15,227 scheduled flights — about 1 in every 71. The reason filed most often was extreme weather, 67.9% of the cancellations coded on this route — about 1 in every 104 scheduled flights.

Of 215 cancelled departures carrying a reason code.

What each reason means

Extreme weather1 in 104

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

146 cancellations, 67.9% of the total.

The airline1 in 246

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

62 cancellations, 28.8% of the total.

The air traffic system1 in 2,175

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

7 cancellations, 3.3% 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.

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

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 1.41% of the time and diverts 0.07% of the time, which a late arrival never shows up in.

Chance of missing is the share of 15,002 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 41 minutes late (90th-percentile gate arrival delay), over 15,227 operations.

Why ATL → CLT runs late

July 2023 – July 2026

Late-arriving aircraft42.4%

the inbound aircraft was late, so this flight started late

The airline38.5%

crew, maintenance, boarding and fueling, all within the carrier’s control

Air traffic control15.2%

airspace and airport capacity, including weather-driven flow control

Weather3.9%

weather severe enough to stop this flight specifically

Security0.1%

screening or terminal security incidents

Share of the delay minutes US DOT attributed to each cause for ATL → CLT. Only delays of 15 minutes or more are attributed.

Late-arriving aircraft is the largest cause on ATL → CLT, at 42.4%: flights here mostly leave late because the plane came in late, and the day shows it: 5–9 AM departures arrived on time 89.4% of the time and 6–9 PM departures 69.4%.
