For months [this cargo airline] has been descending through VFR airspace used by balloons during seasonal operations. The flight path and descending altitude vary greatly. Today the flight path was directly overhead on a VFR descent to ZZZ. As the balloons operate due to fog farther East this spacing gets much closer. We also operate near ZZZ1 and the spacing is closer. We have operated in this limited area [for decades] all most every day. The VFR Sectional Chart does not indicate [this area of heavy balloon traffic]; yet we have been there [for decades]. Turbine exhaust under the air wave of a large Boeing Jet at 800 to 1200 feet might collapse a balloon sending up to 18 passenger down.
