NO, simply put you cannot.
An uber like system was already NIXED by the FAA.
FLYING costs LOTS of money. Do you really want your own plane? Fine, FAR PART 135 Charter company.
Picks you up, flys you to Las Vegas and is paid to wait for you, you pay for hotel room and meals for the pilot too.
OR the pilot flys right back to Phoenix and they charge you for getting the plane home.
BUY a ticket on American, first class and enjoy it.
