A lot of the critical comments I see here are addressed the Uber paper (https://www.uber.com/elevate.pdf https://www.uber.com/elevate.pdf) which is a really interesting read. The cusp of their argument is that several technologies are coming together to make VTOL (vertical take-off and landing) feasible within the next decade. VTOL aircrafts are theoretically much more energy efficient than helicopters, and a lot of the cost associated with planes is due to their low production volume. If a company like Uber started to use VTOL aircrafts, the price would rapidly decline to closer to what cars cost now, and the cost of a flight would be low enough that more than just the wealthy could use them.
