A method includes accessing historical data including timestamped meteorological data and flight path data. The timestamped meteorological data indicates meteorological conditions detected in each of a plurality of geographic regions. The flight path data indicates air traffic volume in each of the plurality of geographic regions during particular time periods. The method also includes, based on the historical data, identifying at least one meteorological condition and at least one time period corresponding to higher than threshold air traffic volume in a particular geographic region of the plurality of geographic regions. The method further includes generating a filter criterion based on the particular geographic region, the at least one meteorological condition, and the at least one time period. The method also includes generating a flight plan based on a portion of the historical data that satisfies the filter criterion.
