Devastating is a bit of an exaggeration with it being responsible for a whooping 3% (at most) of emissions and arguably helping raise the albedo a bit with their contrails.

So it would help a bit, it wouldn't be a game changer though (except if you live near an airport, sound is another pollution that's often ignored).

I would rather we start using blimos what can we do towards that

I mean, I don’t think that’s the way to go about it. Trains don’t take me to my family across the planet in 11 hours. I’d prefer to feel secure when flying there.
