Each comparison pools the flights of other routes, with this route’s own left out. Similar length means within 15% of this route’s 463 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 CMH → EWR flights are cancelled
July 2023 – July 2026
CMH → EWR cancelled 215 of 5,923 scheduled flights — about 1 in every 28. The reason filed most often was extreme weather, 69.3% of the cancellations coded on this route — about 1 in every 40 scheduled flights.
Share of cancellations
Of 215 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.
149 cancellations, 69.3% of the total.
Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.
60 cancellations, 27.9% of the total.
Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.
6 cancellations, 2.8% 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.
215 coded cancellations were recorded on CMH → EWR; the section appears from 50.

Will your connection be tight enough?
Layovers at EWR after arriving from CMH.
| Connection time | Chance of missing | Reads as |
|---|---|---|
| 30 min | 24% | High risk |
| 45 min | 13% | Some risk |

| 90 min | 5.0% | Some risk |
| 120 min | 2.8% | 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 3.63% of the time and diverts 0.17% of the time, which a late arrival never shows up in.
Chance of missing is the share of 5,698 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 26 minutes late (90th-percentile gate arrival delay), over 5,923 operations.
