> from Manhattan to JFK and Newark Liberty Airports cut the travel time from 2-hours to 6 minutes for about the same price as many black cars
A helicopter flight is cool, sure...
...but "2 hours" is complete nonsense. Even if traffic is terrible, you can always take LIRR+AirTrain from Penn Station to JFK for less than $15, and it's basically guaranteed to take 35 min or less, straight to your desired terminal. Heck, I took it this morning, and there was a new train every 10 min.
And most people are going to find it quicker to get to Penn St than to get to the heliport in the first place, so it doesn't even have an advantage there...
