Airships as public transport Yay or nay?

[Deepbluediver]

Could there be political reasons for deterring airplanes in this world? What if there were a war in the setting's past in which airplanes were used to catastrophic effect? Supersonic bombers were used to carpet bomb cities into rubble and were too difficult to intercept. After the war, the resulting peace treaty forbade the development of large airplanes for fear that they could be converted into bombers in anticipation of another war. Airships, on the other hand, are much easier to intercept and are seen as less of a threat.

I think that's an idea that certainly has merit.

I've heard comments about the Gatling-gun, dynamite, airplanes, and the atom-bomb saying, more or less, that each one would be such a terrible weapon that it would bring about the end of war because no one would want to endure the horror of it. So far only the nukes have even come close, not in that they end wars but that governments are extremely reluctant to deploy them. Still it shows that the sentiment is there.
Also, post WWI several of the peace-treaties limited the size of warships, and not only for Germany and it's allies. They broke down eventually, but if something like that delayed the delopment of HtAA until ABZs where already established, it might mean there's cultural or political inertia to maintain the existing system.
