Best time to fly out of Clarksburg (CKB)
North Central West Virginia did not fly enough departures in this window to split the day into time bands. Not enough flights to say. A percentage needs at least 100 flights behind it before it is worth printing; anything thinner is noise wearing a decimal point. These are historical odds, not forecasts. The records say what happened on this schedule over three years; they know nothing about tomorrow’s thunderstorm.

What delays out of CKB were put down to
Airlines file a reason with every arrival running 15 minutes late or more. Across 293 flights that departed CKB and ran 15 minutes late or more, the delay minutes break down with 41.7% put down to late-arriving aircraft and 38.1% to airline operations.
- Late-arriving aircraft 41.7%
- Airline operations 38.1%
- Air traffic & airport volume 14.9%
- Severe weather 4.1%
- Security 1.1%
Late-arriving aircraft is the knock-on category: the plane came in late, so it went out late again. It is why a 7am problem in Newark is still a problem in Denver at dinnertime, and why it is usually the biggest slice on the bar.
