Do I understand you correctly that if we would stop flying right now, we could reverse some effects of global warming (the water vapor part of it would be gone instantly)?

Not to mention the parts of the economy that rely on air travel ;)
Not to mention the remaining parts of the economy which would grind to a halt even if not directly related to air travel
You don't have to to stop flying, only stop flying so high. Low level cloud cover has a massive net cooling effect.
Jet engines are massively more efficient at high altitude. Turbulence is much worse at lower altitude. Safety margins are reduced at lower altitude. Winds are far less predictable at lower altitude.
