The Munich Airport is 3 hr drive from the venue but the biggest airport to fly in to. It will likely have the best flight options from the United States.
Rental Car
You will likely need a rental car to get from the airport to the venue. You need an international drivers license to rent a car and drive in Austria in addition to the US drivers license. An international drivers license can easily be requested through AAA for 20$. Certain roads in Austria require a "Vignette" which can be purchased at almost every gas station. You should purchase the 10 day one which currently costs 9.40€.
