There are more helicopters in SP than anywhere else. Many many buildings have helipads. Several private condominiums a few hours away on the coast also have helipads. Traffic and infrastructure are bad enough that people with the financial means to do so will take helicopters when possible.
If you need someone who can help you get into the market, ping me.
New York Helicopter will get you there now, at $875 per person, 2 minimum, but only to the GA terminal. I don't know how they expect you to get from there to your gate.
Depending on how close you were to the heliport to start out with, say favorably it's a 10 minute walk/cab ride to the helipad, 15 minutes for security and waiting for the helicopter, 10-15 minute flight, 10 minutes to get back airside, 5-10 minutes to the right terminal, reclear security, etc. and it's almost an hour or more in total.
From most places in midtown or lower, it's vastly more convenient to have a black car pick you up and drop you off right in front of your terminal in an hour or so, depending on traffic, while you read, do work, or finish a conference call. You just get in the car, and get out at the other side, clear security once, and go to your gate.
The only time I used it was when I had a meeting a few minutes away from the helipad, I had an international flight I had to make, and traffic was all screwed up due to some major accident, google maps saying it would be 2 hours to get to the airport.
