This idea is already conceived...its called Executive Jet Management, been around for years...
When we first started and only had 2 10s, we actually were on EJM's certificate. We were the client that was referred to in their adds that made $3 million in revenue in a single year.
We never left home base without a paid round trip when we flew NetJet selloffs...and we flew home empty from all over the country all the time when NetJets didn't have anything for us. Not exactly what I'd call efficient, on EJMs part. It was great for us, $3,000,000 later!
