Google Maps tells me Manhattan to JFK Airport is a 32 kilometre taxi ride and takes three hours, plus it takes two hours to clear security at the airport.
I'm a little astounded by those numbers. Five hours to get from the couch at home to the airport. Astounding. I'm through the airport and in Melbourne city in under 2 hours.
I would definitely pay $100 to reduce that. I think $100 helicopter flights is something I would do with friends just to get a drink across town occasionally. How novel!
