Flight Time from Chicago (ORD) to Florence (FLR)

The 7,533 km between ORD and FLR converts to 9.53 hours of flying under the 850 km/h + 40 min model. The slider's steps are anchored on typical hub dwell times, which is why the totals sit at 13 h and 18 h rather than pure multiples.

Mid-band sectors like ORD–FLR (7,533 km) usually carry both non-stops and cheap one-stop alternatives — compare totals at 13 h before choosing. The clock moves 7 h forward (UTC−6 → UTC+1), so a morning departure can land well into the local evening.

Venice (VCE) is the nearest alternative endpoint, 204 km from Florence — close enough that some fares from ORD price it as the same destination. From ORD, reaching VCE instead takes about 0.9 h — less airborne time than the 9.53 h non-stop, and the surface leg into Florence still has to be won back.

Companion flight-time pages exist for 3 of these alternatives (VCE first among them) — see Related calculators. Ground transfer from the alternative airport back into Florence is the catch for arrivals off the ORD service: the 204 km back-offset is time you must win back in fare savings.

A 10:00 departure works out to roughly 02:32 on the clock in Florence — the 9.53 h airborne leg plus the UTC−6 → UTC+1 shift. Budget the ground side too: a standard day runs $189 in Florence versus $230 in Chicago (hotel, three meals, two transit rides), so the arrival city sets the trip's marginal cost.

Florence undercuts Chicago by $41 a day on the dataset averages; let that shape how many nights you book at each end. With 7 hours gained eastbound, the 7,533 km out to Florence ends in a serious jet-lag bill — plan a quiet first day.
