At the moment a lot of planes are bought and sold through facebook groups and the sites that exist are either brokerages charging a % or very old school/poor UX. I'm working on my own marketplace with the key info available and a better UX (maps to find planes at airports near you) etc. Monetization ideas, if it ever goes that far, would be simple sponsored planes higher on the search page like your normal recruitment jobs site.
