Technically not a "jet pack" but a lot simpler to use and with a lot more range. It's called a mini-helicopter. Very cool. Eat your heart out James Bond.

I'll wait for a longer range version that is cheaper. $150,000 would buy a pretty decent fixed wing aircraft. But man it would be a blast to just strap it on to get to work in no time. I live less than 7 miles as the crow flies from the terminal so could be there in less than 7 minutes. Imagine running out for milk and bread? LOL!
