Well jet travel and chemtrails are not the same... jets can and Di contribute to stratospheric pollution but the fumes from it are mainly water and co2, which dissipates rapidly.
Chemtrails.. as I discussed here, are different and deliberate, not a byproduct of jet flight. It doesn’t even come out if the engine emission, it has sophisticated spraying mechanism on the planes
