Flight Time from Chicago (ORD) to Lima (LIM)

Non-stop, the ORD–LIM sector prices out at 7.84 hours — 6,093 km at 850 km/h plus 40 minutes of taxi, climb and approach. Each stopover adds ground dwell at the hub, so the totals model out to about 10.8 hours for one stop and 16.8 for two.

The clock moves 1 h forward (UTC−6 → UTC−5), so a morning departure can land well into the local evening.

Cusco (CUZ) is the nearest alternative endpoint, 575 km from Lima — close enough that some fares from ORD price it as the same destination. From ORD, reaching CUZ instead takes about 1.3 h — less airborne time than the 7.84 h non-stop, and the surface leg into Lima still has to be won back.

Where a matching calculator page exists (ORD → CUZ among them) the links are in the Related list below. Ground transfer from the alternative airport back into Lima is the catch for arrivals off the ORD service: the 575 km back-offset is time you must win back in fare savings.

Leave Chicago at 10:00 and the local arrival clock in Lima reads about 18:50, which tells you whether day one is recoverable. Daily spend shifts at landing: $91 in Lima against $230 at home in Chicago, using the dataset's mid-range figures.

On those numbers Lima is the cheaper place to linger — the gap is $139 per day, which over a week funds a second flight. The modest 1-hour eastbound shift keeps the Chicago–Lima trip easy to absorb.
