Best time to fly out of Pierre (PIR)
Pierre 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 PIR were put down to
Airlines file a reason with every arrival running 15 minutes late or more. Across 111 flights that departed PIR and ran 15 minutes late or more, the delay minutes break down with 45.7% put down to airline operations and 23.4% to late-arriving aircraft.
- Late-arriving aircraft 23.4%
- Airline operations 45.7%
- Air traffic & airport volume 19.9%
- Severe weather 11%
- Security 0%
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.
