Train or bus travel is significantly longer, approximately 7 hours. If flying between Venice and Vienna (within the Schengen Area), there is typically no passport control. However, visa validity checks might occur.
For transportation from Vienna International Airport (VIE) to the city center, options include express trains (like Railjet - RJ) which take about 15 minutes. There is no direct metro line from the airport to the city center, but other train services are available.
