Hi QuinnPerry, if you can get a direct flight to London Heathrow from Montana, there are many flights to Vienna. Flying time from Heathrow to Vienna is 2hrs 15 mins. There are direct flights to LHR from Denver. Hope this is of some use to you. Dont know whether you have been to Vienna before, but it is the most beautiful and cultured city, places to see are St Peters Cathedral, the Schonbrun Palace, the Vienna Cemetery to see the graves of the composers etc, and call in at Druckers Pattisserie for the most beautiful gateaux and fresh cream cakes and Viennese Coffee. Austria is a stunningly beautiful country I'm sure you will enjoy it.
