Best time to fly out of Hays (HYS)

Hays 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.
