Captain Amaranth
I am seriously contemplating building my own airship (if/when I get enough money) ~ 'tis one of the reasons I'm studying Engineering ~ but I would never charge that much for rides. D:
Possibly, that's because I'm in it for the fun, not excessive amounts of profit.
i have spent the past half a year drawing up some plans for an airship of my own.
its looks are inspired by one of the airships (the twin-pod one) from the inside cover artwork on the latest reprint of Mortal Engines.

main differences on my designs are that the pods are closer together, and the propellors are closer to the hull...
together captain, we can re-invigorate airship travel (and you know, have a race or three!)
