Why ORD → CMH flights are cancelled

July 2023 – July 2026

What each reason means

Extreme weather1 in 92

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

133 cancellations, 68.9% of the total.

The air traffic system1 in 259

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

47 cancellations, 24.4% of the total.

The airline1 in 937

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

13 cancellations, 6.7% 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.

Connection buffer and chance of missing by layover length, ORD → CMH arrivals

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 1.58% of the time and diverts 0.10% of the time, which a late arrival never shows up in.

Chance of missing is the share of 11,976 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 54 minutes late (90th-percentile gate arrival delay), over 12,181 operations.
