Best time to fly out of Sheridan (SHR)
Sheridan 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 SHR were put down to
Airlines file a reason with every arrival running 15 minutes late or more. Across 368 flights that departed SHR and ran 15 minutes late or more, the delay minutes break down with 49.1% put down to airline operations and 31.1% to late-arriving aircraft.
- Late-arriving aircraft 31.1%
- Airline operations 49.1%
- Air traffic & airport volume 13.9%
- Severe weather 5.6%
- Security 0.3%
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.
