Flight Time from Las Vegas (LAS) to Florence (FLR)

Block time for Las Vegas → Florence is about 11.97 hours non-stop on the site's cruise model. The slider's steps are anchored on typical hub dwell times, which is why the totals sit at 14.5 h and 18.5 h rather than pure multiples.

The clock moves 9 h forward (UTC−8 → UTC+1), so a morning departure can land well into the local evening.

Flexible-flier trick: price LAS against FLR and then against each nearby field below — secondary endpoints within 300 km sometimes clear the fare by a full cabin class. From LAS, reaching VCE instead takes about 0.9 h — less airborne time than the 11.97 h non-stop, and the surface leg into Florence still has to be won back.

Where a matching calculator page exists (LAS → VCE, LAS → FCO among them) the links are in the Related list below. Weigh each alternative against its back-distance to Florence — from LAS, a cheap fare hundreds of km from your actual destination is rarely cheap once the surface leg is priced.

Put a departure hour on the math: wheels-up at 10:00 from LAS puts you on the ground at FLR around 06:58 local time, once the 9-hour gain is applied. Budget the ground side too: a standard day runs $189 in Florence versus $210 in Las Vegas (hotel, three meals, two transit rides), so the arrival city sets the trip's marginal cost.

Florence undercuts Las Vegas by $21 a day on the dataset averages; let that shape how many nights you book at each end. With 9 hours gained eastbound, the 9,610 km out to Florence ends in a serious jet-lag bill — plan a quiet first day.
