Flight Time from Las Vegas (LAS) to Vienna (VIE)

Non-stop, the LAS–VIE sector prices out at 11.81 hours — 9,475 km at 850 km/h plus 40 minutes of taxi, climb and approach. One connection is the realistic worst case for most calendars: expect the total to land near 14.3 hours with a single well-chosen hub, and near 20.3 hours with two.

Past the 9,000 km mark this is an ultra-long-haul sector: the 11.81 hours in the air plus cabin time makes a one-stop routing with a lounge stop worth pricing against the non-stop. Between UTC−8 and UTC+1 you gain a 9-hour head start on the day — worth remembering when you schedule the first dinner or call.

Flexible-flier trick: price LAS against VIE and then against each nearby field below — secondary endpoints within 300 km sometimes clear the fare by a full cabin class. From LAS, reaching BUD instead takes about 0.9 h — less airborne time than the 11.81 h non-stop, and the surface leg into Vienna still has to be won back.

Where a matching calculator page exists (LAS → BUD, LAS → PRG among them) the links are in the Related list below. Ground transfer from the alternative airport back into Vienna is the catch for arrivals off the LAS service: the 214 km back-offset is time you must win back in fare savings.

A 10:00 departure works out to roughly 06:49 on the clock in Vienna — the 11.81 h airborne leg plus the UTC−8 → UTC+1 shift. Daily spend shifts at landing: $191 in Vienna against $210 at home in Las Vegas, using the dataset's mid-range figures.

Vienna undercuts Las Vegas by $19 a day on the dataset averages; let that shape how many nights you book at each end. With 9 hours gained eastbound, the 9,475 km out to Vienna ends in a serious jet-lag bill — plan a quiet first day.
