Best time to fly out of La Crosse (LSE)

La Crosse 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.

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.
