well, there seems to be uncanny valley between flying an airline, even in business/first class and private jet using something like prepaid fractional card (like NetJet Marquis - last time i heard it was 100K for 25 hours, today probably somewhat higher).

Of course the valley is for the reason, yet for some above mentioned people it may look like a business opportunity. Anyway, they raised 2M - peanuts for VC to explore on practice whether it is opportunity or not.
