What you are describing seems outside the scope of this particular aircraft model.These are meant to land on existing helipads in NYC. From the article, the business model is to cut down 1-2 hour commutes to and from the JFK airport to seven-minute flights. Never mind the helipad space, just boarding hundreds of passengers and their luggage would cut severely into that time saving.

But it is fundamental issue. Unless you have extremely large number of helipads. The throughput is limited to capacity of landing, deboarding, boarding and lift off. Is the 7 minutes from lift off to landing or just travel time in air? How long does boarding and deboarding take, especially with luggage? Can this system reach more than low dozens passenger per hour by pad?

That doesn't matter as much when each passenger is happy to pay thousands of dollars for the privilege.

24 pax/hr * $1000/pax * 12 hr/day = $288,000/day in revenue
